Psychiatric Services

Capstone employs one part-time psychiatrist and three full-time Physician's Assistants (PA). These providers work with patients and their mental health therapist (if applicable) to diagnose and treat mental health conditions with the use of psychotropic medications. The provider will meet with each patient for an evaluation appointment to create the best individualized treatment plan.
