PSYCHIATRIC SERVICES

We offer a variety of treatments to meet the needs of every patient in search of psychiatric care, including options such as:

TMS Therapy
Transcranial magnetic stimulation (TMS) is a safe, non-invasive treatment option for depression, OCD, PTSD, anxiety, and other mental illnesses.

Ketamine Infusion
In recent years, ketamine therapy has emerged as an extraordinarily successful treatment for those who have not experienced lasting results from other treatment options.

Medication Management
Medications such as antidepressants are a common mental health treatment. Many patients find symptom relief with medication, but it’s important to find the most effective medication or combination of medications for your condition. A professional psychiatrist can help you to determine your best options.

ADHD Testing
At Serenity, we use the QbTest to diagnose children, adolescents, and adults with ADHD.

PSYCHIATRIC CONDITIONS WE TREAT

Serenity offers TMS and ketamine therapy as a treatment option for many mental health conditions, including:

Depression
There are many distinct types of depression, including major depressive disorder (MDD), postpartum depression, treatment-resistant depression, seasonal affective disorder (SAD), and more.

Anxiety
Anxiety disorders include diagnoses of panic disorder, social anxiety disorder, specific phobias, or obsessive-compulsive disorder.

Obsessive-Compulsive Disorder (OCD)
Compulsions can manifest in the form of excessive cleaning, repetitive actions, arranging things in a precise way, repeatedly checking things such as light switches or locked doors, and compulsive counting.

ADHD
ADHD contains three subtypes: primarily inattentive, primarily hyperactive-impulsive, and combined, which includes symptoms of both inattentive and hyperactive-impulsive. ADHD treatment options such as medication management can help patients to manage symptoms.

Serenity also treats other conditions such as post-traumatic stress disorder (PTSD) and bipolar disorder.
