About Premier Psychiatry
Led by Pradeep Thapar, MD, FAPA, owner of the practice since 1999, Premier Psychiatry provides comprehensive, individualized psychiatric care for children, adolescents, adults and older adults.
Comprehensive, individualized psychiatric care.
Premier Psychiatry is a psychiatry practice serving children, adolescents, adults and older adults. Under the leadership of Pradeep Thapar, MD, FAPA, every new patient begins with a comprehensive psychiatric evaluation that reviews symptoms, history, prior treatments and goals before any treatment is recommended.
From there, your provider builds an individualized treatment plan centered on medication management, with advanced options such as TMS and Spravato® when appropriate. Appointments are available in person in Orland Park and Willowbrook and by telehealth.

The Four Pillars of Premier Psychiatric Care
The principles that guide how we care for every patient.
1. Comprehensive Diagnostic Evaluations
Each initial evaluation reviews your history, previous treatments and current symptoms, so we can build an accurate diagnosis and a trusting partnership with you.
2. Advanced Treatment Options
When antidepressants have not helped enough, the practice offers FDA-approved Spravato® (esketamine) nasal spray for adults, given only in a REMS-certified setting with monitoring for at least 2 hours after each dose, and non-invasive Transcranial Magnetic Stimulation (TMS). Your provider can discuss whether either may be appropriate for you.
3. Pharmacogenomic Testing
When clinically appropriate, GeneSight® testing uses a cheek swab to look at genetic variations that can affect how your body processes certain medications. Results can help inform, not dictate, medication decisions.
4. Timely, Accessible Care
Same-day or next-day appointments when available. Our psychiatrists, nurse practitioners and physician assistants see patients in person in Orland Park and Willowbrook and by telehealth. Contact our team to check availability.
