Ketamine-Assisted Psychotherapy

Ketamine has been FDA-approved since 1970 and is the one psychedelic medicine that can be offered legally in psychotherapy today. I offer it in three forms, always inside a genuine therapy relationship, with preparation and integration.

Low-dose lozenge KAP

Ketamine-assisted talk therapy in 50-minute sessions at my Gramercy Park office. A gentle, sublingual low dose softens defenses while leaving you able to speak, feel, and work, therapy first, medicine in service of it.

Moderate-to-psychedelic dose KAP

One-on-one intramuscular ketamine sessions at InnerMost, a non-ordinary state therapy, training, and research center in Manhattan, where I serve on faculty. Deeper journeys, with medical support, full preparation, and integration.

How I Work

Medicine inside a relationship

Ketamine-assisted psychotherapy can be a meaningful catalyst to therapy: it loosens defenses, helps access feeling, and can be a method to new understandings. My approach draws on the EMBARK model, with attention to the existential, spiritual, embodied, emotional, relational, and emergent processes that may come up in the work.

Research suggests ketamine can meaningfully reduce depression and anxiety for many people; it also has limits and risks, which we discuss honestly before any treatment. KAP isn't right for everyone, and a careful medical and psychological screening comes first.
