Providers
The Southlake Psychiatry PC team creates a welcoming, nonjudgmental atmosphere for our patients. Our goal is to provide the best psychiatric care with a deep understanding that patients are not merely "cases" or "diagnoses", but instead, are people with unique experiences of their symptoms and individual paths to their recovery. Our belief is that medication can be instrumental in recovery, yet often only one part of a person's treatment. We help patients find the next logical step in their recovery, gaining and maintaining their improvement for the long-term. We wish to share knowledge and experience with our patients regarding available options in order to help everyone make the most informed, productive and collaborative treatment decisions as they move towards well-being.
For continuity of care and support, your initial provider will be YOUR provider throughout your care at Southlake Psychiatry PC.
