Group Fee: $1500
Required Medical Evaluation: $250*
*A brief online medical evaluation is required and may be reimbursable through your insurance.
We partner with Emily Hackenburg, PMHNP/FNP-BC for telehealth medical evals. Each evaluation takes about 45 - 60 minutes. Once you are enrolled in the group, we will connect you to Emily to set up your evaluation.
What Your Group Fee Includes
Your $1,500 group fee includes 10 hours of therapist-led care across one preparation session, two ketamine sessions, and one integration session.
You will also have two trauma-informed therapists supporting the group throughout the program, providing a level of therapeutic support that may not be available through a traditional ketamine clinic.
Medical evaluation and ketamine medication are separate costs and are coordinated with a prescribing physician. Payment plans are available.
More Than Ketamine
One of the unique benefits of group therapy is that you aren't navigating the ketamine experience alone. Many ketamine clinics focus primarily on the medical administration of ketamine and may offer limited or no ongoing psychotherapy.
At Third Nature Therapy, two experienced trauma therapists will be present throughout the group experience, with dedicated preparation and integration sessions to help you make meaning of what emerges.
The group model also makes ongoing KAP more financially accessible while maintaining a high level of therapeutic support, safety, and connection.
Why Group KAP?
Ketamine can open a door—but what happens around the experience matters.
For many people, ketamine treatment ends when the medication wears off. Group KAP offers something different: an opportunity to continue this work within a supportive therapeutic relationship and a community of people doing their own inner work.
Group KAP offers:
Continued access to ketamine therapy at a lower cost than ongoing individual KAP.
Two trauma-informed therapists present during your ketamine sessions, rather than receiving ketamine with limited therapeutic support.
Preparation and integration to help you approach each experience intentionally and bring what emerges into your everyday life.
The healing potential of community—experiencing your own inner process alongside others while remaining focused on your individual journey.
A small, intimate setting where you can build familiarity and trust with your facilitators and fellow participants.
