OUR VISION

We believe that you deserve more than “merely coping.”

Acheron Psychiatry views symptoms as a sacred calling, and portal to authenticity, meaning, and resiliency. We are devoted to particularly serving the most vulnerable aspects of the self, and of society. Our approach uses depth psychology to treat root causes and supports human potential and thriving.

WE OFFER

Ketamine-assisted psychotherapy, neurocognitive care, medication management, and psychotherapy.

We are committed to helping our patients understand their own deep, meaningful, and complex narratives in an empathic, supportive, and judgment-free atmosphere.
