Ketamine
Assisted Psychotherapy

Ketamine-Assisted Psychotherapy

Ketamine-assisted psychotherapy is a groundbreaking, integrative, trauma-informed experience that can be used to improve a wide range of mental health symptoms. Ketamine has a completely different mechanism of action from any other antidepressant medication and offers hope to the millions of people who have not found adequate help through therapy and medication alone.

Ketamine is a medicine that helps you access deeper parts of your psyche, and in the context of therapy, may help you understand this material in ways that may have been inaccessible in traditional talk and trauma therapy. Ketamine-assisted therapy is effective because we will create a safe and intentional “set and setting,” which refers to the environment and context in which you take the medicine, as well as the preparation and integration experiences.

What is Ketamine?

Ketamine is an FDA-approved "dissociative anesthetic", since 1970, for the purpose of surgical anesthesia in high doses. Since the early 2000’s, when used in low dosage, Ketamine has been found to be extremely safe and highly effective in treating depression, anxiety, PTSD, and addiction as an FDA “off-label” use, in combination with psychotherapy. Similarly, ketamine supports personal growth and self-exploration, tapping into one’s inner healing wisdom.


Ketamine normalizes the brain’s default mode network (DMN) activity. Think of the DMN as your brain’s usual mode of operation. The DMN is active when you are in wakeful rest such as daydreaming or mind wandering. It is also active when you are thinking about others, thinking about yourself, remembering the past, and planning for the future. Resetting the DMN can create an opportunity to get unstuck from negative thinking patterns and establish hope for a healthier future.

Ketamine also enhances neuroplasticity by significantly increasing Brain-Derived Neurotrophic Factor (BDNF). Increased neuroplasticity can help undo the loss of neural connection commonly caused by long-term depression. Ketamine also blocks receptors for glutamate, a neurotransmitter associated with brain inflammation and excitotoxicity. Inflammation is another common factor in people with long-term depression.

These mechanisms are not found in other antidepressants and appear to help explain the rapid, powerful antidepressant effects of ketamine.

Ketamine-Assisted Psychotherapy As A Deeply Curated Healing Experience

Ketamine-assisted psychotherapy is not a quick medical intervention. It can be tempting to join an online ketamine program or try a sterile IV clinic, but these lack something that only ketamine-assisted psychotherapy with a trained therapist can provide: safety, intentionality, ceremony, and depth. It is a deeply intentional, trauma-informed psychedelic experience designed to support emotional healing, nervous system regulation, and expanded self-understanding. Every session is thoughtfully curated with ample time to prepare, journey, and integrate.

This work is ideal for individuals healing from:

  • Narcissistic abuse

  • Complex trauma and PTSD

  • Debilitating anxiety and fear

  • Attachment wounds

  • Spiritual crisis or identity transitions

  • Depression resistant to traditional therapy

  • Or simply feeling like you are stuck in therapy or "life" and need a fresh approach

 

Unlike brief clinical ketamine sessions, this model honors the full arc of the experience.​​​

A Slower, More Intentional Approach

Abstract Swirling Colors
Preparation

We clarify your intentions, explore emotional readiness, and design a container that feels safe and aligned.

 

A minimum of 1-4 preparation sessions are required to assess your appropriateness for ketamine-assisted psychotherapy, to identify mental health and trauma history, and goals for treatment.

 

Some people with complex trauma or anxiety about the session may need more time to prepare.

 

We will not begin until you are ready. 

Ceremony & Ritual (Optional)

All sessions are created with intention and care to create the right "set" (prepare your mindset for the journey) and "setting," or a safe, quiet place created specifically for your journey. Headphones and eyeshades are provided, along with a curated music playlist. 


Depending on your needs and beliefs, sessions may include:

 

  • Grounded, heartfelt ceremony

  • Creation of an altar

  • Spiritual or archetypal framing, tarot cards, poetry readings

  • Energy clearing

  • Neutral but intentional opening and closing rituals

  • Breathwork, meditation, journaling

This is collaborative. Some clients prefer sacred language. Others prefer psychological language. Both are welcome.

The Medicine Experience


You are supported in a calm, private setting with music and therapeutic presence while you are under the influence of the medicine, lasting 2–3 hours.

 At therapeutic doses, ketamine can create a deeply relaxing, perspective-shifting state that supports insight, emotional release, and expanded awareness.

Integration & Lingering

There is unhurried time to reflect, process, and gently return. The integration period is just as important as the journey itself.
