Parker sits at the heart of one of the fastest-growing parts of metro Denver. Douglas County has expanded rapidly over the last two decades, drawing young families, professionals, veterans, and first responders to its mix of newer neighborhoods, top-rated schools, and proximity to both the city and the foothills. It’s also a community that, like much of the Front Range, has lived through more than its share of difficult collective events in recent years—from school violence within the county itself to wildfires and mass casualty incidents elsewhere along the corridor that touched south metro families closely. PTSD shows up across this community in many forms, and it deserves specialty care that’s familiar with all of them.
Our location at 9399 Crown Crest Boulevard, Suite 401 sits just off Parker Road near Parker Adventist Hospital, with easy access from E-470, Lincoln Avenue, and CO-83. Patients coming from Parker, Lone Tree, Highlands Ranch, Castle Rock, Castle Pines, Centennial, Aurora, Franktown, and Elizabeth can typically reach us without crossing into Denver proper—and significantly faster than commuting downtown for specialty care.
Post-traumatic stress disorder is a mental health condition that can develop after a person experiences or witnesses a traumatic event. The triggering event might be a single incident—a serious accident, an assault, a sudden loss, a medical emergency, an act of violence—or it might be repeated exposure to high-stress situations over time, as is common for military members and first responders. PTSD can also develop from being closely connected to an event without being physically present, particularly when the people or places involved were part of your daily life. PTSD affects the brain’s ability to process memories, regulate emotion, and distinguish past danger from present safety, which is why symptoms can feel so overwhelming and so disconnected from current circumstances.
It is important to recognize that PTSD is not a sign of weakness or something you can simply “get over.” It is a treatable neurobiological condition that responds well to evidence-based care. People with PTSD may relive the trauma through flashbacks or nightmares, avoid reminders of the event, feel constantly on edge, or feel emotionally numb and disconnected from the people they love. None of that means something is wrong with who you are. It means the nervous system learned to keep you alive in a moment of extreme threat and hasn’t yet been given the tools to know it’s safe to stand down.
PTSD symptoms vary widely from person to person, but they typically cluster into four areas:
Intrusive memories. Flashbacks, nightmares, unwanted recurring memories, or strong physical reactions to reminders of the trauma. These can feel like reliving the event, not just remembering it.
Avoidance. Steering clear of places, people, activities, or even conversations that bring up reminders of what happened. This can shrink someone’s life significantly, often without people realizing it.
Negative changes in mood and thinking. Persistent guilt or shame, distorted beliefs about oneself or others, emotional numbness, loss of interest in things that used to matter, or feeling disconnected from loved ones.
Heightened arousal. Being easily startled, sleep problems, irritability or outbursts, hypervigilance, difficulty concentrating, or feeling like you can’t relax even in safe environments.
Complex PTSD typically arises from prolonged or repeated trauma—ongoing abuse, captivity, sustained exposure to combat, repeated medical trauma, or childhood adversity. It includes the core symptoms of PTSD but also involves harder-to-shake patterns: difficulty regulating emotion, persistent feelings of shame or guilt, problems trusting others, and a fractured sense of self. Complex PTSD requires a treatment approach that pays attention to relationship and identity, not just symptom reduction.
PTSD also frequently co-occurs with other conditions—depression, anxiety disorders, substance use, chronic pain, OCD, and sleep disorders are all common. When PTSD and another condition show up together, treating only one of them usually doesn’t work; we assess the full picture during your first visit and build an integrated plan that addresses what’s actually present.
Trauma can happen to anyone, but certain patterns show up more often in the communities we serve. Naming them isn’t about defining anyone by their experiences—it’s about reducing the shame that keeps people from asking for help:
Community-wide events and secondary trauma. The Front Range has lived through a series of high-profile incidents in recent years—from school violence within Douglas County itself to events in nearby Aurora, Boulder, and Colorado Springs. Many of our patients weren’t physically present at these events but were closely connected: a parent of a student, a friend of someone who was there, a first responder who showed up, a teacher who returned to class the next week, a community member whose ordinary routines were rewritten by what happened. Secondary or vicarious trauma is real and treatable, and you don’t owe anyone an apology for being affected by something that affected your community.
Motor vehicle accidents. The south metro’s high-speed suburban corridors—E-470, I-25, Parker Road (CO-83), Lincoln Avenue—carry heavy traffic, and serious MVAs are common. MVA-related PTSD is frequently underdiagnosed and is one of the most treatable forms of PTSD when patients get specialty care.
Military service and combat exposure. The south Denver metro has a substantial veteran population, including service members connected to Buckley Space Force Base and veterans who chose the area for its quality of life. Combat-related PTSD, military sexual trauma, and the cumulative effects of multiple deployments all respond to evidence-based care. We accept Champ VA and coordinate with VA Eastern Colorado HCS when patients are also using VA benefits.
First responder and emergency services exposure. Fire, EMS, law enforcement, and dispatch personnel across Douglas and Arapahoe County—South Metro Fire Rescue, Parker PD, Douglas County Sheriff’s, surrounding agencies—carry repeated exposure to traumatic incidents. Cumulative occupational trauma is real, and the “you signed up for this” framing that often surrounds it makes it harder to ask for help, not easier.
Medical trauma. ICU stays, difficult births, cancer treatment, sudden medical emergencies, and pandemic-era healthcare experiences can all leave lasting PTSD. So can being a healthcare worker—nurses, techs, and physicians at Parker Adventist, Sky Ridge Medical Center, Castle Rock Adventist, and the broader HealthONE and CommonSpirit networks carry their own version of medical trauma.
Wildfire trauma and evacuation experiences. The 2021 Marshall Fire in nearby Louisville and Superior reminded the entire Front Range how quickly fire can move through suburban neighborhoods. For patients whose trauma involved evacuation, property loss, or watching a community burn, the annual wildfire smoke season and the news coverage of new fires can both trigger significant symptom flares.
Assault, abuse, and loss. Survivors of physical or sexual assault, intimate partner violence, childhood abuse, or sudden traumatic loss often live with PTSD for years before getting specialized care. The barrier is rarely the willingness to heal—it’s finding someone who knows how to help.
Our trauma-informed approach is the foundation of everything we do. We build safety and trust from the first session, move at a pace that respects your nervous system, and explain every step clearly so that nothing feels coercive or surprising. Treatment is collaborative—you are always in control of what we work on, when, and how. Choice and consent aren’t checkboxes; they’re how trauma treatment actually works, because the wrong pace can re-create the helplessness the trauma started with.
We work with your timing. Some patients are ready to talk about specific events in early sessions; others need months of stabilization first. Both paths are legitimate, and we don’t push anyone faster than they can sustain.
Parker, Lone Tree, Castle Rock, Highlands Ranch, and the surrounding south metro suburbs are tight-knit communities where neighbors know each other through schools, sports, churches, and shared social networks. Concerns about being seen at a mental health clinic are legitimate and common. We take them seriously. Mental health treatment records are protected by HIPAA, our office is set up to be private rather than visible, and our extended hours (early morning, late evening, and Saturday) make it possible to get care without rearranging your week in ways that prompt questions. You don’t owe anyone an explanation for taking care of yourself.
In-person appointments in Parker provide a valuable opportunity for direct interaction with experienced clinicians who specialize in trauma care. Whether you are commuting from Lone Tree, Highlands Ranch, Castle Rock, Centennial, or further out from Elizabeth or Franktown, these sessions allow for thorough assessments, personalized therapy, and real-time adjustments to treatment.
For trauma work in particular, being physically present matters. Clinicians can observe subtle signs of activation that virtual care can miss, support grounding in real time, and provide the kind of steady presence that helps the nervous system settle. We also pace sessions so you leave each appointment feeling more settled, not more activated.
Living on the Front Range creates conditions that can interact with PTSD symptoms in ways patients in other parts of the country don’t experience. We’ve noticed several patterns worth naming, because patients are often relieved to learn they aren’t imagining the connection:
Wildfire smoke season and fire-related activation. From late spring through early fall, smoke days are a recurring feature of Front Range life. For patients whose trauma involved fire, evacuation, or property loss—including the 2021 Marshall Fire and other recent events—smoke alone can trigger significant symptom flares. We plan ahead with patients each spring so the tools are in place before the air thickens.
Severe thunderstorms, hail, and tornado activity. The south metro sits in hail alley, and severe storms with significant hail damage are a regular feature of spring and summer. For patients whose trauma involved sudden weather events, flooding, or storms during deployment, these can be difficult stretches.
Altitude, sleep, and hyperarousal. Parker sits at roughly 5,900 feet, and altitude affects sleep architecture even for long-time residents. Poor sleep makes every PTSD symptom worse—nightmares, irritability, hypervigilance, emotional reactivity. Prazosin and sleep-focused treatment matter in this climate, and we consider altitude when adjusting medications.
Winter darkness and seasonal mood interaction. Colorado winters bring short days and long stretches indoors. For patients whose PTSD co-occurs with depression—which is common—the seasonal layer can compound symptoms. We screen for this and adjust treatment accordingly.
Year-round outdoor access for recovery. The upside is that south metro proximity to Cherry Creek State Park, Castlewood Canyon, and the Front Range foothills supports the kind of behavioral activation that’s a real part of PTSD recovery. Walking the Cherry Creek Trail, getting back onto a favorite trail, returning to the things you loved before the trauma—recovery from PTSD involves reclaiming the world, not just reducing symptoms.
Our clinic in Parker, CO offers a comprehensive range of PTSD treatments designed to work together. We combine evidence-based trauma-focused psychotherapy, medication management, and advanced neuromodulation to provide care that meets you where you are. Our goal is to reduce symptoms, restore functioning, and help you reclaim the parts of your life that PTSD has narrowed.
PTSD treatment is not one-size-fits-all. Some patients respond well to medication alone, others benefit most from trauma-focused therapy, and many find the greatest relief through a combination of approaches—often layered over time as the nervous system stabilizes and deeper work becomes possible.
Several psychotherapies have strong evidence for PTSD, and the right choice depends on the person and the trauma. We offer or coordinate the three most established approaches:
Cognitive Processing Therapy (CPT). A structured, time-limited therapy that helps patients identify and revise the “stuck points” that trauma often leaves behind—beliefs about safety, trust, control, esteem, and intimacy that no longer match present reality. CPT is typically 12 sessions and works well for patients who prefer a more verbal, structured approach.
Prolonged Exposure (PE). A trauma-focused therapy that involves gradually approaching memories, situations, and reminders of the trauma in a safe, controlled way so the nervous system can learn that the threat is past. PE is highly effective and is delivered at a pace you control.
Eye Movement Desensitization and Reprocessing (EMDR). A therapy that uses bilateral stimulation (typically eye movements) while a patient briefly attends to trauma memories, helping the brain reprocess them so they no longer carry the same emotional charge. EMDR is well-established for PTSD and is often a good fit for patients who find detailed verbal description of trauma too difficult.
The choice between approaches is collaborative. We discuss the options during your evaluation and match the therapy to your goals, your readiness, and the kind of trauma you’re working through.
Medication can play an important role in PTSD treatment, especially when sleep, mood, and hyperarousal symptoms are severe enough to make therapy hard to engage with. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly prescribed for PTSD; sertraline and paroxetine are the two SSRIs with FDA approval specifically for PTSD, though others are also commonly used. These medications can reduce depression, anxiety, irritability, and intrusive symptoms over a course of weeks.
Prazosin deserves special mention. Originally a blood pressure medication, prazosin has been shown to significantly reduce the frequency and intensity of trauma-related nightmares for many patients. For PTSD patients whose nights have become the worst part of their day, prazosin can be transformative—not because it treats the underlying trauma, but because restoring sleep often opens the door to everything else that needs to happen in recovery. We monitor blood pressure carefully when prescribing prazosin and pay close attention to how altitude affects dosing.
Our medication management services in Parker are led by two board-certified psychiatrists, Dr. Heath Canfield, DO, and Dr. Dustin Froehlich, MD, who oversee careful monitoring of dosage, side effects, and overall effectiveness. We prioritize safety, especially around sleep medications, blood pressure considerations with prazosin, and any other medications you may already be taking. Regular follow-ups ensure adjustments can be made promptly.
Transcranial magnetic stimulation (TMS) is a non-invasive treatment that uses targeted magnetic pulses to stimulate areas of the brain involved in mood regulation and trauma processing. TMS is FDA-approved for depression and has shown meaningful benefit for PTSD symptoms, particularly when medication and therapy alone have not been sufficient.
TMS sessions are conducted in a comfortable clinical setting, easily accessible from E-470, Parker Road, and the south metro corridor. The procedure is typically well-tolerated, requires no sedation or recovery time, and patients can drive themselves home and return to normal activities the same day. Many patients report improvements in sleep, mood, and overall emotional reactivity over a course of treatment.
Ketamine is a newer, fast-acting option for PTSD, particularly for patients with treatment-resistant symptoms or significant depression alongside their PTSD. Unlike traditional antidepressants, which work through serotonin and can take weeks to show effect, ketamine acts on the glutamate system and can produce noticeable symptom relief within hours or days.
Ketamine therapy is delivered under medical supervision in a series of carefully monitored sessions. In Parker, we integrate ketamine into a broader treatment plan—typically alongside trauma-focused therapy, because the window of reduced symptom intensity that ketamine opens can be a powerful time to do the deeper psychological work that trauma recovery requires. Ketamine is not appropriate for everyone, and we’ll have a clear conversation about whether it’s the right fit during your evaluation.
People whose trauma comes from service to others often face their own set of barriers to care: cultural expectations of toughness, concerns about how treatment will affect a career or security clearance, and the legitimate sense that civilian providers don’t always understand the work. We take all of that seriously.
For veterans and service members, including those connected to Buckley Space Force Base, we approach treatment with respect for the culture and complexity of military service. We accept Champ VA and coordinate with VA Eastern Colorado HCS when patients are also using VA benefits. For first responders—South Metro Fire Rescue, Parker PD, Douglas County Sheriff’s, Lone Tree PD, and surrounding agencies—we understand cumulative occupational trauma and the unique challenge of treating PTSD in someone who still has to go back on shift. For healthcare workers and medical trauma survivors at Parker Adventist, Sky Ridge Medical Center, Castle Rock Adventist, and elsewhere, we recognize the particular layer of trauma that comes from being both witness and participant in critical moments.
We’re not a VA clinic and not a peer-support program, but we work alongside both, and many of our patients use multiple resources together. What we add is specialty-level psychiatric and trauma care delivered close to home.
Our Parker clinic is led by two board-certified psychiatrists, both with training in mood, anxiety, and trauma-related disorders:
Dr. Heath Canfield, DO — Board-certified Psychiatrist. View profile.
Dr. Dustin Froehlich, MD — Board-certified Psychiatrist. View profile.
Our Parker team takes a trauma-informed, patient-first approach grounded in evidence-based practice: treatment plans built around your specific symptoms and goals, transparent conversations about what each option can and can’t do, and a steady pace that respects your nervous system. With extended hours, same-week appointments, and Champ VA accepted, we’re committed to delivering the same caliber of specialty PTSD care available in any major metro—right here in the south Denver suburbs.
Starting PTSD treatment can feel daunting, and we know that walking through the door is sometimes the hardest part. 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.
You won’t be asked to describe your trauma in detail at the first visit unless you choose to. We’ll talk about what’s bringing you in, how symptoms are affecting your life, your history, and your goals. The actual trauma work, if and when you decide to do it, happens at a pace and a moment that you and your clinician choose together.
The comprehensive evaluation includes a detailed clinical interview, standardized PTSD assessments, screening for co-occurring conditions (depression, anxiety, substance use, sleep disorders, OCD), and—when appropriate and with your permission—input from family members or other healthcare providers. This process helps identify the full picture of what you’re carrying, which is the only way to build a treatment plan that actually addresses it.
We also explore your history with PTSD, any previous treatments, and the strategies you’ve already been using to cope. That history matters; it tells us what’s been tried, what’s helped, and what to do differently this time.
Following the evaluation, we collaborate with you to create a personalized treatment plan that aligns with your needs and preferences. This plan outlines the recommended therapies, medication options, and any additional supports that may be beneficial. Goals in PTSD treatment often start practical—better sleep, fewer nightmares, less reactivity—and expand from there into the broader work of reclaiming the life you want.
We encourage open communication and ongoing feedback so that treatment stays responsive to your evolving needs. Recovery from PTSD is not linear; we expect that and adjust the plan accordingly.
