Ketamine-Assisted Therapy (KAT) in Bozeman, Montana

If you looking for deeper, more lasting mental health counseling support for depression, anxiety, grief or trauma…


At Sub Rosa Therapy, we offer a unique form of psychotherapy called Ketamine-Assisted Therapy (KAT) — a structured, research-informed treatment that combines counseling with psychedelic medicine to support meaningful change. KAT is offered only when clinically appropriate and always grounded in strong therapist relationships that support integration of expanded state experiences.

What is Ketamine-Assisted Therapy?

KAT is not a quick fix. It’s therapy enhanced by expanded states of consciousness and integrated into life through therapy.

Ketamine is a legal psychedelic with fast-acting antidepressant effects. When used in conjunction with therapy, it can reduce mental rigidity, soften defenses, and bring deeper emotional truths to the surface — all within a safe, therapeutic relationship with a skilled mental health therapist.

At Sub Rosa, therapy remains central. Ketamine is a supportive tool, not a standalone treatment.

Who Is KAT For?

KAT may help if you're experiencing:

  • Depression or anxiety

  • Trauma or PTSD

  • Grief, numbness, or shame

  • Recovery from addiction

  • Obsessive or rigid thinking

  • Emotional stuckness or spiritual crisis

Before starting, all clients complete:

  • A mental health evaluation with a psychiatric mental health NP

  • A medical screening with a licensed provider

Together we determine whether KAT is the right fit for your needs.

How KAT Works at Sub Rosa

KAT is delivered as a structured series over 4 to 16 weeks. Each series includes:

  • Preparation sessions to build safety and intention

  • Ketamine sessions via intramuscular (IM) administration

  • Integration sessions to help you process and apply insights

You can work with a Sub Rosa therapist or continue with your existing counselor during the series.
