Psychedelic Healing

Compassionate, evidence-informed support for deep healing and lasting change

Psychedelic-assisted therapy is a powerful catalyst for transformation when held with skill, safety, and intention. My work integrates advanced clinical training, years of frontline research experience, and a steady, compassionate presence to accompany you into the quiet terrain of your deepest inner work.

A Leader in the Field

I am a graduate of the first cohort at the California Institute of Integral Studies’ Center for Psychedelic Therapies and Research program in 2016—the first accredited training of its kind. This foundation shaped my commitment to combining rigorous clinical practice with the healing potential of psychedelic medicines.

Since 2010, I’ve specialized in trauma-informed therapy and psychedelic facilitation. My experience includes working as both a therapist and consultant on the MAPS MDMA-Assisted Therapy clinical trials, contributing directly to the development of one of the most groundbreaking mental-health treatments of our time and gaining 

Licensed, Ethical, and Experience-Driven

I am the second person in Colorado to be licensed in Natural Medicine Clinical Facilitation under the state’s evolving state regulated framework. I also founded and operate HAPPY REBEL HEALING the first Natural Medicine Healing Center in Boulder, Colorado, designed to offer legally supported, thoughtfully structured psychedelic-assisted services. Our center was featured in the Boulder Reporting Lab in November 2025, highlighting our who we are and our mission to be a part of bringing psychedelic healing to the world. We hold this work in a deeply sacred and careful manner.

My work includes extensive experience with:

  • Psilocybin – for depression, existential inquiry, and spiritual exploration
  • MDMA – for trauma resolution, relational growth, and deep emotional processing
  • Ketamine – for treatment-resistant depression and acute emotional stabilization

A Safe, Supported Journey

Whether you are seeking relief from long-standing patterns or exploring new dimensions of self-understanding, I offer a therapeutic environment grounded in presence, ethics, and care. Your process is honored at every step—from preparation, to the medicine experience, to integration—so that insights become embodied, sustainable change. I offer both high dose journeys for the deep intense work as well as low dose therapy intensives – combining the mind and heart opening medicine with evidence based treatments such a EMDR and IFS.
