Home / San Tan Valley, AZ / ADHD Testing and Treatment
San Tan Valley is a fast-growing community of young families, working professionals, first responders, healthcare workers, retirees, and commuters who travel far for work. ADHD shows up across all of these populations. In kids and teens, we see it in the J.O. Combs USD, Florence Unified, Queen Creek Unified, and surrounding district students who are bright but struggle with focus, follow-through, or organization. In adults, we see it in patients who have built compensatory strategies over decades and finally hit a wall—a new job, a new baby, a long commute, a divorce, a missed deadline that wasn’t supposed to happen. The diagnosis is liberating for many adults, and it changes outcomes for kids when caught early.
Our location at 36457 N. Gantzel Road, Suite 102 sits near Gantzel and Combs, easily accessible from the SR-24 connector, Hunt Highway, and the broader SVT/Queen Creek road network. Patients coming from across the Southeast Valley and Pinal County—Queen Creek, Florence, Apache Junction, Gold Canyon, Coolidge, Casa Grande—can typically reach us without driving into Phoenix. We’re open Monday through Friday from 6:00 AM to 9:00 PM and Saturday from 7:00 AM to 7:00 PM, with same-week appointments available.
ADHD (attention-deficit/hyperactivity disorder) is a neurodevelopmental condition that affects the brain systems responsible for attention regulation, impulse control, working memory, time perception, and executive function—the set of skills involved in planning, starting, and completing tasks. ADHD is biological, it’s heritable (running strongly in families), and it persists across the lifespan in most people who have it. It is not caused by parenting, sugar, screen time, or moral failure.
There’s no blood test for ADHD, but it’s one of the most well-studied conditions in psychiatry, and diagnosis through careful clinical evaluation is reliable when done properly. The challenge is that ADHD symptoms overlap with many other conditions—anxiety, depression, sleep disorders, trauma history, learning disorders, autism spectrum, thyroid problems, and the ordinary stresses of modern life—which is why a careful diagnostic process matters more than a quick checklist.
ADHD presents in three main patterns, and people often shift between them across the lifespan:
Predominantly inattentive presentation. The pattern that used to be called “ADD.” Difficulty sustaining attention, easily distracted, trouble finishing tasks, disorganization, forgetfulness, losing things, appearing to not listen when spoken to, daydreaming. This presentation is most often missed in girls, in quiet kids, in high-achieving students who compensate hard, and in adults who appear functional but exhaust themselves doing so.
Predominantly hyperactive-impulsive presentation. Fidgeting, restlessness, difficulty staying seated, talking excessively, interrupting, blurting out answers, difficulty waiting, acting before thinking. This is the most visible pattern and the one most likely to get noticed early, especially in boys. In adults, the physical hyperactivity often quiets into internal restlessness while the impulsivity remains.
Combined presentation. Significant symptoms across both inattentive and hyperactive-impulsive categories. This is the most common presentation in patients formally diagnosed.
In children, ADHD often shows up first at school, where the demands of sustained attention, organized work, and impulse control are highest. Common signs include:
Attention and focus. Difficulty paying attention in class, careless mistakes, trouble following multi-step directions, losing homework and supplies, appearing to not listen, daydreaming, difficulty finishing tasks they started.
Activity and impulsivity. Fidgeting, getting out of seat, running or climbing when it’s not appropriate, talking excessively, interrupting, blurting out answers, difficulty waiting turn, acting without thinking.
Organization and executive function. Difficulty managing time, trouble starting homework, losing things, forgetfulness, messy backpacks and lockers, missed deadlines, last-minute everything.
Emotional regulation. Frequent frustration, emotional intensity that seems out of proportion, difficulty handling transitions, big feelings that come on fast and pass quickly. Emotional dysregulation isn’t in the formal DSM criteria for ADHD, but it’s one of the most common features.
Social and family impact. Conflicts with siblings, difficulty with peer relationships, parental exhaustion from the daily management, homework battles that take three hours for thirty minutes of work.
Adult ADHD often looks different than childhood ADHD. The hyperactivity that was visible in kids becomes internal restlessness in adults, while the attention and executive function challenges remain or become more disabling as life demands grow. Common adult patterns:
Work and career. Procrastination on important tasks (with last-minute scrambles), missed deadlines, difficulty starting projects, trouble with sustained focus during meetings, brilliant work followed by stretches of unproductivity, hitting a career ceiling because the executive function demands have outgrown your compensatory strategies, repeated job changes when the novelty wears off.
Time and planning. Chronic lateness despite trying, underestimating how long things take, difficulty managing multiple deadlines, the experience of time as “now and not-now” rather than as a continuous progression.
Home and relationships. Household tasks pile up, finances slip through the cracks, partners frustrated by uneven contribution, important things forgotten, the persistent guilt of being “supposed to be better at this.”
Emotional patterns. Rejection sensitivity (intense reaction to perceived criticism or rejection), emotional intensity, difficulty regulating mood across the day, restlessness when not stimulated, the need for novelty and the boredom of routine tasks.
Self-perception. A lifetime sense of underperforming relative to potential. The exhausting work of compensating. The feeling of being “lazy” or “broken” that doesn’t match how hard you’ve actually been trying. For many adults, getting an accurate diagnosis is the first time someone has named what’s been going on—and that recognition itself is significant.
Adult ADHD is one of the largest patient populations we see, and the path to diagnosis often follows recognizable patterns:
The child-diagnosed pathway. Many parents bring their child in for evaluation, hear the symptoms described, and realize they recognize themselves. ADHD runs strongly in families—if your child has it, there’s a meaningful chance you do too. We see this regularly, and it’s often the start of much-needed adult treatment that should have happened years earlier.
The wall-hit pathway. Compensatory strategies that worked in your twenties—coffee, deadline pressure, a partner who handled the organization, the structure of school—stop working in your thirties or forties when life demands grow. A new job, a new baby, a divorce, a promotion, a parent who needs care, a partner who isn’t picking up the slack anymore. The system breaks, and the underlying ADHD becomes impossible to mask.
The treatment-resistant pathway. Many adults have been treated for years for anxiety or depression that didn’t fully respond, with the underlying ADHD never identified. About half of adults with ADHD have a co-occurring mood or anxiety condition, and treating only the depression or anxiety usually doesn’t work. When we identify ADHD in patients already in treatment for something else, we adjust the plan to address the actual full picture.
The grief and relief of late diagnosis. Many adults experience a complicated mix of feelings after diagnosis—relief at finally having an explanation for decades of struggle, grief for the time and energy lost to undiagnosed ADHD, and sometimes anger at having been mislabeled as lazy, scattered, or unmotivated for years. These reactions are normal and worth discussing as part of treatment.
It’s not too late. Patients sometimes worry that diagnosis in their 40s, 50s, or 60s is “too late” to matter. It isn’t. Treatment improves daily function, work performance, relationships, and quality of life at any age. The patients we see most often tell us that they wish they had come in years sooner—and that the only thing they wish they’d done differently was to come in faster once they suspected.
Childhood and adolescent ADHD typically gets identified first by parents and teachers who notice patterns at school or at home that don’t fit the usual developmental trajectory. We treat kids and teens across the Pinal County school districts—J.O. Combs USD, Florence Unified, Queen Creek Unified, and the surrounding districts—and our approach involves:
Careful diagnostic evaluation. A thorough assessment that includes parent and teacher input, standardized rating scales, careful screening for co-occurring conditions (anxiety, depression, learning disorders, autism spectrum, sleep problems), and—when appropriate—the QbTest for objective measurement of attention and impulsivity.
Family involvement throughout treatment. Parents are an essential part of pediatric and adolescent ADHD care. We coach parents on the behavioral strategies that support kids with ADHD, the communication patterns that reduce conflict, and the ways to advocate for accommodations at school without inadvertently increasing pressure.
Coordination with schools. ADHD diagnosis is often a starting point for IEP or 504 accommodations that can include extended time on tests, preferential seating, organizational support, or reduced homework loads. We provide the diagnostic documentation; you and the school work out the specifics.
Adolescents specifically. Teens with ADHD face increased academic demands, social complexity, and the early emergence of decisions about driving, substance use, and relationships—all of which interact with ADHD in important ways. ADHD treatment in adolescence is associated with better long-term outcomes across many domains, including reduced risk of substance use problems and motor vehicle accidents.
ADHD frequently shows up alongside other mental health conditions, and treating only one usually doesn’t work. About half of adults with ADHD have a co-occurring anxiety or depression diagnosis. ADHD often accompanies learning disorders, autism spectrum, sleep disorders, and substance use disorders. Many adults have been treated for anxiety or depression for years before someone notices the ADHD underneath—and the depression or anxiety often improves significantly when the ADHD is properly addressed.
During your first visit, we assess the full picture rather than just the most obvious symptom. Treatment plans that address the actual constellation of what’s going on tend to work better than plans that target one diagnosis in isolation.
Beyond the standard presentations, certain patterns show up frequently in our SVT patient population. Naming them isn’t about defining anyone by their stressors—it’s about recognizing that some of what people are carrying is shaped by the realities of life here:
Adult ADHD in the commuter community. Many SVT residents commute long distances daily to work in the broader Phoenix metro. Long commutes are particularly difficult for adults with undiagnosed ADHD—sustained driving attention is exactly the kind of task ADHD makes harder, and the fatigue of compensating during the drive amplifies symptoms once you arrive at work or home. We see this pattern often, and treatment can meaningfully reduce both daily strain and driving safety risk.
First responder ADHD. SVT has a substantial first responder community, and ADHD is notably common in this population. Many adults with ADHD self-select into fire, EMS, law enforcement, or military careers because the constant variability, real stakes, and immediate-action structure of the work matches their neurology. Diagnosis often happens later in career—when administrative demands grow, when promotion creates desk responsibilities, or when the body can no longer compensate for accumulated sleep deprivation. ADHD treatment helps with the administrative and home-life dimensions while preserving the operational strengths.
Healthcare worker ADHD. Similar self-selection happens in healthcare—nursing, EMS, surgical roles, and clinical work all have ADHD-friendly elements. Documentation requirements, charting, and the administrative dimensions of healthcare are often where ADHD becomes disabling for clinicians who are otherwise excellent at patient care.
Pediatric and adolescent ADHD in young-family Pinal County. The SVT area has a heavily young-family population. Pediatric ADHD evaluation is one of the most common reasons families come to us, often starting with concerns raised by teachers in elementary or middle school. Early diagnosis and treatment significantly improve academic, social, and family outcomes.
Late-life ADHD diagnosis in the retiree community. Some of our older patients are getting their first ADHD diagnosis in their 60s or 70s, after a lifetime of compensatory strategies that stopped working in retirement. Without the external structure of work and the partner-and-family scaffolding that retirement sometimes thins out, undiagnosed ADHD becomes more visible. Treatment can substantially improve quality of life and reduce frustration in late-life patients.
Living in the Southeast Valley creates conditions that interact with ADHD in ways patients in milder climates don’t experience:
Heat and sleep disruption. Arizona summer heat affects sleep quality, and sleep deprivation amplifies every ADHD symptom—attention falls, emotional regulation worsens, impulsivity rises, executive function degrades. For kids and adults with ADHD, the four-to-five-month stretch of high heat can be the hardest part of the year for symptom management.
Indoor confinement and stimulation hunger. Kids and adults with ADHD often rely on physical activity and outdoor stimulation to regulate. When summer heat keeps everyone indoors, the absence of normal physical outlets can make ADHD harder to manage. Indoor activity, structured exercise, and stimulant medication scheduling around the indoor stretches all matter.
Outdoor recovery in the cooler months. The upside of the Arizona climate is that October through April offers excellent conditions for the outdoor activity and physical movement that support ADHD management—San Tan Mountain Regional Park, the Superstitions, broader Southeast Valley trails. Movement matters for ADHD, and our climate supports it for two-thirds of the year.
ADHD diagnosis done well isn’t a 15-minute conversation and a prescription. Our evaluation process includes:
Detailed clinical interview. A thorough conversation about current symptoms, lifetime history (ADHD by definition shows up by age 12, even when diagnosis happens decades later), school history, work history, family history, and the specific ways symptoms have affected your life.
Standardized rating scales. Validated questionnaires that you complete (and that parents and teachers complete for kids), which help structure the diagnostic picture.
QbTest computer-based assessment. A 15-20 minute computer-based test that objectively measures attention, impulsivity, and activity. The QbTest doesn’t diagnose ADHD by itself, but it adds objective data to the clinical picture and is particularly useful in distinguishing ADHD from anxiety or other conditions that can mimic it.
Screening for co-occurring conditions. Anxiety, depression, learning disorders, autism spectrum, sleep disorders, substance use, and medical conditions like thyroid problems that can mimic or contribute to ADHD symptoms.
Rule-outs. Sleep disorders (especially obstructive sleep apnea, which can present like ADHD), thyroid problems, medication side effects, substance use, and other conditions that can cause attention symptoms in the absence of ADHD.
Diagnostic feedback. A clear conversation about the findings—what we see, what we don’t see, and what we recommend—rather than a one-line diagnosis and a prescription.
Once we have an accurate diagnosis, treatment is highly individualized. The main components:
Stimulant medications are the most extensively studied and most effective first-line treatment for ADHD in both kids and adults. There are two main families: methylphenidate-based medications (Ritalin, Concerta, Focalin, and others) and amphetamine-based medications (Adderall, Vyvanse, and others). Both families work by enhancing the activity of dopamine and norepinephrine in the brain’s attention and executive function systems. About 70-80% of patients respond to one of the two families, and finding the right medication, formulation, and dose often takes some trial.
Short-acting versus long-acting. Short-acting formulations last 3-5 hours and may be used for specific high-demand parts of the day. Long-acting formulations last 6-12 hours and provide steady coverage across a school or work day. The choice depends on the patient’s life and preferences.
What patients typically notice. Improved ability to start tasks and sustain attention, reduced procrastination, less internal noise, more ability to follow conversations and meetings, less emotional reactivity, and a general sense of being able to access executive function that was previously out of reach. Most patients describe feeling more like themselves on medication, not less.
Patients often have legitimate questions about stimulants—about safety, dependence, personality changes, side effects, controlled substance considerations, and the recent national stimulant shortage. We treat these questions seriously.
Safety and addiction. Properly prescribed, monitored, and taken stimulants have a strong safety profile in patients with ADHD. Despite their classification as controlled substances, prescription stimulants taken as directed for ADHD do not produce the addiction pattern seen with recreational stimulant misuse. Importantly, treated ADHD is associated with lower rates of substance use disorders than untreated ADHD—the self-medication risk runs in the other direction.
Side effects. Common side effects include reduced appetite, difficulty falling asleep, headache, mild increase in heart rate or blood pressure, and—occasionally—irritability or emotional flattening that signals the dose is too high. Most side effects are manageable with dose or timing adjustments. We monitor closely, especially in the first few months.
National stimulant shortages. Ongoing supply issues with several stimulant medications have made things harder over recent years. We can’t guarantee a specific medication will be available at a specific pharmacy on a specific day, but we work with you on alternative formulations, on pharmacy options across the Southeast Valley and Phoenix metro, and on bridge plans when shortages affect your refill. We don’t write a prescription and disappear when problems arise.
Controlled substance prescribing. Stimulants are Schedule II controlled substances, which means specific federal regulations around prescribing, refills, and monitoring. There are no automatic refills; we typically see patients regularly for medication management, and we follow standard practices around responsible prescribing. This is not a barrier to care—it’s how we provide care that’s actually accountable.
For patients who don’t tolerate stimulants well, who have specific medical contraindications, who prefer to avoid controlled substances, or who haven’t responded to multiple stimulant trials, non-stimulant options are available:
Atomoxetine (Strattera) works through norepinephrine rather than dopamine, takes 4-8 weeks to reach full effect, and provides 24-hour coverage. Particularly useful for patients with co-occurring anxiety or for those who don’t want a controlled substance.
Guanfacine (Intuniv) and clonidine (Kapvay) are alpha-2 agonists originally used for blood pressure that have been shown to help with ADHD, particularly with the hyperactive-impulsive and emotional regulation features. Sometimes used alongside stimulants for combination effect.
Bupropion (Wellbutrin) isn’t FDA-approved specifically for ADHD but has good evidence of effectiveness, especially in adults with co-occurring depression.
Viloxazine (Qelbree) is a newer non-stimulant option approved for both kids and adults.
Medication addresses the neurochemistry; behavioral approaches and skills training address the practical realities of living with ADHD. Both matter, and combination treatment usually works better than either alone. For adults, this often includes structured approaches to time management, task initiation, organization, and the emotional regulation features of ADHD. CBT specifically adapted for adult ADHD has good evidence and is often the right next step alongside medication.
For kids and teens, behavioral approaches involve coaching parents, structuring routines, working with schools, and—when appropriate—direct skill-building with the child. ADHD-focused therapy can substantially improve outcomes when combined with medication, and we provide referrals to trusted local therapists when therapy is the right next step.
ADHD diagnosis is often the foundation for formal accommodations that can substantially improve outcomes. At school, this typically means an IEP (Individualized Education Program) or 504 Plan that can include extended time on tests, preferential seating, organizational support, reduced homework loads, or other modifications appropriate to the student. At work, ADA accommodations can include flexible scheduling, written instructions, quiet workspaces, or other reasonable adjustments. We don’t run the accommodation process for you, but we provide the diagnostic documentation that supports your case.
Our medication management services in San Tan Valley are led by Jason Adams, PMHNP, and Colleen Fornear, PMHNP, both experienced psychiatric nurse practitioners who oversee careful monitoring of dosage, side effects, and overall effectiveness. We prioritize finding the right medication at the right dose with minimal side effects, which often takes some adjustment. Regular follow-ups ensure changes can be made promptly, and—particularly important for controlled substances—we maintain the kind of ongoing relationship that responsible stimulant prescribing requires.
Starting ADHD evaluation can feel uncertain—especially for adults who have wondered for years whether ADHD might explain things but have hesitated to find out. Your first visit is designed to be welcoming, thorough, and unhurried. Most first appointments run 60 to 90 minutes—long enough to actually hear your story without rushing through it.
We’ll talk about what’s bringing you in, your current symptoms, your lifetime history, what’s been tried before, and your goals. Diagnosis isn’t usually completed in one visit; we typically gather additional information through rating scales, the QbTest when appropriate, input from family or teachers (with your permission), and rule-outs before reaching a final diagnostic picture. For parents bringing children, the first visit includes both parent interview and time with the child appropriate to age and the situation.
The comprehensive evaluation is what makes specialty ADHD diagnosis different from a primary care checklist. It includes a detailed clinical interview, lifetime history review, standardized rating scales (often completed by you and a partner or parent), screening for co-occurring conditions, careful rule-outs of conditions that can mimic ADHD, and—when appropriate and helpful—the QbTest for objective measurement.
The goal isn’t to assign a diagnosis quickly; it’s to develop an accurate picture of what’s actually going on so that treatment addresses the real problem. ADHD can look like anxiety, depression, trauma response, sleep disorder, or learning disability, and treating it as ADHD when it’s something else doesn’t work. We take the time to get this right.
Following diagnosis, we collaborate with you to create a personalized treatment plan that fits your needs and preferences. The plan outlines recommended treatments, expected timeline, and how we’ll measure progress. Goals in ADHD treatment often start practical—better focus on work or school, fewer missed deadlines, less procrastination, better follow-through, less day-end exhaustion—and expand from there into the broader work of building a life that fits how your brain actually works.
We encourage open communication and ongoing feedback so that treatment stays responsive to your evolving needs. ADHD treatment isn’t always linear; we expect that and adjust the plan accordingly.
In-person appointments in San Tan Valley provide a valuable opportunity for direct interaction with experienced clinicians. Whether you are coming from across SVT, Queen Creek, Florence, Apache Junction, or further out in Pinal County, these sessions allow for thorough assessments, real conversations about treatment options, and the kind of steady, present care that virtual visits can’t fully replicate.
For ADHD evaluation in particular, being physically present matters. Clinicians can observe the subtle signs—movement, attention shifts, eye contact patterns—that help round out the clinical picture. For controlled substance prescribing specifically, the in-person relationship is part of how we provide responsible care.
Our San Tan Valley clinic is led by two experienced psychiatric nurse practitioners with training in mood, anxiety, ADHD, and related conditions:
Jason Adams, PMHNP — Psychiatric Nurse Practitioner.
Colleen Fornear, PMHNP — Psychiatric Nurse Practitioner.
Our San Tan Valley team takes a patient-first, evidence-based approach: careful diagnostic evaluation, transparent conversations about what each treatment option can and can’t do, and a steady pace that respects how you’re actually doing. With same-week appointments, extended hours, AHCCCS and Tricare accepted, and responsible controlled substance prescribing, we’re committed to delivering specialty ADHD care that’s both rigorous and genuinely accessible.
Our clinic is located at 36457 N. Gantzel Road, Suite 102 in San Tan Valley, AZ 85140, near Gantzel and Combs in the heart of the SVT community. We serve patients from across the Southeast Valley and Pinal County, including Queen Creek, Florence, Apache Junction, Gold Canyon, Coolidge, Casa Grande, and the surrounding communities.
Both. Adult ADHD is one of the largest groups of patients we see. Many adults come to us after their child is diagnosed and they recognize the same patterns in themselves, after years of feeling like they’re working twice as hard for the same results, or after coping strategies that worked in their 20s stopped working in their 30s or 40s. Adult ADHD is real, common, often missed, and very treatable. We also treat children and adolescents across J.O. Combs USD, Florence Unified, Queen Creek Unified, and the surrounding Pinal County school districts.
No, it’s much more than a checklist. Our ADHD evaluation includes a detailed clinical interview about current symptoms and lifetime history, standardized rating scales, screening for co-occurring conditions (anxiety, depression, learning disorders, sleep problems, substance use, autism spectrum), review of medical history that can mimic or contribute to ADHD symptoms, and—when appropriate—the QbTest, a computer-based objective measure of attention, impulsivity, and activity that adds objective data to the clinical picture. For kids, we typically also include input from parents and teachers; for adults, we often include input from a partner or family member if you’d like.
We understand this concern. National stimulant shortages have made things harder over the last few years, and we can’t promise a specific pharmacy will have a specific medication on a specific day. What we can do is prescribe responsibly, work with you on pharmacy options across the Southeast Valley, consider alternative formulations or non-stimulant options when stimulants aren’t available, and provide the kind of ongoing relationship that controlled substance prescribing requires. We don’t write a script and disappear; we work with you to keep treatment going.
No—and this is one of the most common concerns we hear, especially from parents considering medication for their child. Properly dosed ADHD medication doesn’t change who you are; it helps the executive function systems that are already part of you work more reliably. Most patients describe feeling more like themselves on medication, not less. Side effects exist and we monitor them carefully, but the personality concern is largely a misconception.
ADHD diagnosis is often a starting point for IEP or 504 accommodations at school, which can include things like extended time on tests, preferential seating, reduced homework loads, or organizational support. We can provide diagnostic documentation that supports your child’s case for accommodations at J.O. Combs USD, Florence Unified, Queen Creek Unified, or any other district. We don’t run the accommodation process for you, but we provide the clinical foundation it rests on.
We are in-network with most major insurance plans including Aetna, Blue Cross Blue Shield, Cigna, Optum, United Healthcare, Tricare West, AHCCCS (Arizona Medicaid), Banner Health, and many others. Please contact our San Tan Valley office at 480-956-5720 to verify your specific coverage before your first appointment. Some elements of testing (like the QbTest) may have separate coverage considerations; we’ll walk through that with you.
