Patient Review
“I’ve been living with Complex PTSD and anxiety for most of my adult life. While treatment helped me keep my head above water, I never felt like I was healing. Now, thanks to Ketamine Therapy at Liminal Medicine, I’m not just treading water with my mental health anymore — I’m actually moving forward.” — Patient Testimonial
About Liminal Medicine
Liminal Medicine is a woman- and queer-owned integrative healing center in Sebastopol, California, specializing in ketamine-assisted psychotherapy. The practice takes a relationship-based, whole-person approach that combines modern medicine with individual healing practices.
The clinical team includes Dr. Suegee Tamar-Mattis (Medical Director, board-certified in Family Medicine), Celeste Monnette (Clinical Director, LCSW with 25+ years experience and published KAP research), and additional licensed therapists trained in ketamine-assisted psychotherapy through the California Institute for Integral Studies and Polaris Insight Center.
Treatment typically begins with a free 15-minute phone consultation, followed by medical and psychological intakes, a preparation session, and the KAP session itself. Integration sessions help patients process and apply insights from their ketamine experiences. Group sessions and First Fridays boosters provide ongoing community support.
