A comprehensive evaluation, then a plan built around you.
Every new patient begins with a comprehensive psychiatric evaluation. Your provider reviews your concerns, history, past treatment and goals, and you decide on an individualized treatment plan together.
Your evaluation
- A review of your symptoms, history, past treatment and goals
- Pharmacogenomic (genetic) testing when your provider thinks it may help
- A clear explanation of your diagnosis and treatment options
Your ongoing care
- Medication management and follow-up visits with your provider
- In-person or telehealth appointments
- Advanced options such as TMS and Spravato® when appropriate

When antidepressants are not enough.
Premier Psychiatry offers two advanced treatment options for depression that has not improved enough with antidepressants: Spravato® (esketamine) nasal spray and TMS therapy. Whether either is right for you is decided after an evaluation. TMS is offered at our Orland Park office, and Spravato® at both our Orland Park and Willowbrook offices.

Spravato® (Esketamine) Therapy
A nasal spray taken in a REMS-certified healthcare setting under the direct observation of a healthcare provider. Spravato is FDA-approved for adults with treatment-resistant depression (on its own or with an oral antidepressant) and, together with an oral antidepressant, for depressive symptoms in adults with major depressive disorder who have acute suicidal thoughts or behavior; it has not been shown to prevent suicide or to reduce suicidal thoughts or behavior. Its boxed warning covers sedation, dissociation, respiratory depression, abuse and misuse, and suicidal thoughts and behaviors.

Transcranial Magnetic Stimulation (TMS)
A non-invasive, FDA-cleared treatment that uses magnetic pulses to stimulate brain circuits involved in mood. No anesthesia is needed. The most common side effects are discomfort where the coil sits, scalp or face tingling and mild headaches; seizures are possible but the risk is low.
Suboxone® treatment for opioid dependence.
Outpatient treatment for opioid dependence, delivered with dignity and respect. Suboxone® can reduce withdrawal symptoms and cravings as part of a complete treatment plan.
Call our office to ask about current availability for a consultation.
