Meet Our Providers
Meet our team of experienced psychiatrists, nurse practitioners, and physician assistants caring for patients across Orland Park, Willowbrook, and telehealth.
An experienced team of psychiatric providers.
At Premier Psychiatry, our clinicians do not practice in isolation. Led by Pradeep Thapar, MD, FAPA, our psychiatrists, nurse practitioners, and physician assistants work in close clinical consultation.
Whether you need careful medication adjustment, an evaluation for treatments such as Spravato® and TMS, or ongoing medication management, our team works together on your care. Our online scheduler shows each provider's current availability.
Why Our Provider Team Stands Apart
- Comprehensive Evaluations: A thorough review of your history before treatment is recommended.
- Academic Rigor: Training at UIC, Northwestern, Wayne State, Loyola, and the Edward Hines, Jr. VA Hospital.
- Treatment Options: TMS is offered at our Orland Park office, and Spravato® at both our Orland Park and Willowbrook offices.

Finding the Right Clinician for You
A strong working relationship with your clinician matters. When you contact Premier Psychiatry, it can help to think about three things:
Your Clinical Needs
If you are interested in Spravato® or TMS, ask our office about eligibility and next steps. TMS is offered at our Orland Park office, and Spravato® at both our Orland Park and Willowbrook offices.
Demographic & Age
Pradeep Thapar, MD, FAPA, completed a Child and Adolescent Psychiatry Fellowship. Ask our office which providers see patients in your age group.
Modality Preference
Ask about in-person visits at our Orland Park or Willowbrook offices or telehealth video visits. Telehealth video visits are available for patients located in Illinois or Indiana during the visit. Availability varies by provider, and our office will confirm whether a video visit is right for you.
