Ketamine Assisted Psychotherapy (KAP)


Ketamine is a dissociative anesthetic medicine which can produce consciousness expanding experiences. Using ketamine in a therapeutic container can catalyze change in a unique way. Often people report the breaking of patterns and opening of the heart.  Safely altering consciousness invites us into a world beyond our everyday understanding, providing sensations and material that are finally new, or bring a felt sense of something lost being found.  Some common changes as a result of  KAP are:

  • decreased sense of fear
  • decreased negative self talk
  • increased frustration tolerance
  • increased compassion for self and others
  • spiritual growth
  • a break from rumination

Please contact me for more information on the KAP process.

A comprehensive resource for learning about ketamine and KAP is KRIYA Institute.


Psychedelic Integration


Psychedelic experiences can range from elating to traumatic.  Through a connective integration process, these experiences can both settle and grow. Gaining insight about the psyche’s journey and getting support for the feelings evoked may lead to an enlivening and heartfelt process that can be  lived out in a daily way.  


Individual Therapy


I work deeply and psychodynamically with an anti-oppression lens.  Through inner exploration and collaboration in therapy,  we can make sense of some of life’s complexities and the suffering they may cause. In the process, relationships with self and others can ultimately become more aligned and more loving. I deeply believe that the therapy process can unfold meaning, connection and internal freedom, bringing us closer to who we really are. My specialties include trauma, grief and LGBTQ issues.

Couples Therapy


Relationship therapy can uncover new insights and burgeon better communication.  I work with couples to uncover truths that may be masked in old dynamics. Intimacy and compassion can evolve through a deeper understanding of these inner workings.  Whether the couple is searching for a lifeline, wanting to explore and grow, or preparing to dissolve the partnership, couples therapy can make transitions smoother and more meaningful.
