I am a psychotherapist and licensed clinical social worker (LCSW) based in Corvallis, OR, with a bachelor’s in comparative literature from Harvard and a Master of Social Work (MSW) from Smith College. I have worked as a mindfulness-based psychotherapist in many clinical settings including Oregon State University, Asian Counseling and Referral Service, and the PTSD Outpatient Clinic in the Puget Sound VA.

For my psychedelic training, I am grateful to have learned from underground guides, Sheree M. Godasi of PsychedeLiA, and offerings from the Portland Psychedelic Society.

My own path to healing and freedom began in earnest when depression, anxiety, and a gnawing sense of existential emptiness inspired me to take a leave of absence from college and begin practicing meditation. Over the next 14 years, I continued to meditate and sit retreats in Zen, Burmese, and Tibetan Buddhist traditions, including a kyol che retreat at Musangsa Temple in South Korea with Kwan Um Zen Master Dae Bong.

While my meditation practice offered relief from my distress as well as meaningful insights, it wasn’t until I paired meditation with the awakening potential of psychedelics that I finally realized: I am not a person in a body in the universe; instead, subjectively speaking, “universe,” “body,” and “person” are constructions within the indivisible continuum of nondual awareness.

If you’re curious to open up to your own true nature as awareness, I would love to point you to what is there right now, even as you read this sentence. And whatever else your goals and needs may be, my passion and purpose are to help support you contemplatively, emotionally, and psychologically through your own path of sensemaking and liberation.


How I work with clients

I offer in-person and online therapy and coaching sessions to anyone exploring or curious to explore expanded states of consciousness (via meditation and/or psychedelics) along their psychological, emotional, and spiritual path. When it comes to mental health challenges, I specialize in treating depression, anxiety, trauma, veteran or servicemember issues, grief, relationship distress, and end of life concerns.

For contemplatives, I offer a nonjudgmental space for meditation troubleshooting and nondual awakening guidance. I help meditators to process and integrate openings and awakenings—or alternately, to heal from Dark Night experiences, distressing retreat drop-outs or aftermaths, abuse within spiritual communities, discouragement, derealization, depersonalization, spiritual bypassing, rigid “meditator” ego structures, shadow repression, and other concerns.

For explorers of psychedelic healing, I provide therapeutic support for microdosing as well as pre/post integration counseling for journeys with psilocybin, 5-MeO-DMT, N,N-DMT, ayahuasca, MDMA, LSD, mescaline, ketamine, iboga, and others. I’m particularly interested in supporting clients exploring the cross-pollination of meditation and psychedelics along the path of nondual awakening.

In my role, I serve as a therapeutic integration specialist for clients using psychedelics on their own, with guides, or in legal clinical trials and settings. I do not provide psychedelic-assisted sessions or access to psychedelics.

My primary therapeutic modalities are Mindfulness, Acceptance & Commitment Therapy (ACT), Nondual Therapy, Narrative Therapy, Voice Dialogue, Gestalt, Psychodynamic, and Jungian. I enjoy working with clients from a wide variety of backgrounds, so familiarity with these particular approaches is by no means a prerequisite for working with me.

If you’re curious about whether we’ll be a good match, I offer an introductory 20-minute session. My therapy and coaching services are free of charge, and there are no fees for reserving, rescheduling, or canceling appointments. I work on a gift economy model and simply request donations. Suggested donations are $20 for the 20-minute introductory session and $150 for each 50-minute session, but there is no minimum required amount for either. This system is rooted in generosity and trust, and is designed to improve access and foster equity for those facing financial barriers. I also accept Oregon Health Plan, and I am an out-of-network provider for all other insurance plans. Superbills for claiming out-of-network benefits are available upon request. To start our journey together, use the booking tool on my website (see link above) to schedule your first appointment.
