Frank Larson, M.D.

Frank began his career in health care when he graduated from medical school in 1987. Previously a surgeon, he's now grateful for the opportunity to help people support their mental health through the use of plant medicines to achieve greater insight and awareness.

He helped gather signatures in 2020 to place Measure 109, the Psilocybin Services Initiative, on the Oregon ballot that November. Frank is a member of the Central Oregon Psychedelic Society, the Psilocybin Facilitator Association, and the Psilocybin Assisted Therapy Association. He also participates in regular peer review with psilocybin facilitator colleagues.

He uses a mindfulness-based approach in his facilitation work and enjoys assisting all those drawn to plant medicines. This includes those challenged with substance use, anxiety (including end-of-life), depression, PTSD, those who feel stuck in their life, and those who desire personal growth and/or to (re)connect with spirit.

To further his understanding of plant medicines and healing, Frank has participated in transformative group ceremonies led by a Mazatec healer in Mexico. Through his work, he’s discovered valuable connections in his life between the past and present and established priorities that help him focus on living mindfully. His free-time activities include hiking, kayaking, snowboarding, gardening, yoga, and meditation.

Frank’s goal is for your experience to be meaningful and safe. He comes to this work with humility, and also respect – for the natural world that shares these medicines, for our ability to connect with our inner healer, and for our potential to achieve inner freedom.

“I was a psilocybin newbie and Frank was a great guide. He offered thoughtful help before, during, and after my experience. And beyond that, I found Frank to be kind and compassionate. I won’t hesitate to work with Frank again.”  (E.F.)

“After my wife’s passing in 2022 I became immersed in, what I call, a gauntlet of grief. Suffice to say, mind/body manifestations of this complicated grief were debilitating for me while I pursued grief counseling, extensive reading, and countless YouTube and TED Talk videos. Although I intellectually evolved in my understanding of grief I had reached an impasse with an ability to align my spiritual connection with my deceased wife with my conscious debilitating ruminations and inability to realize self-forgiveness.

Although I casually heard about the potential benefits of psychedelics for depression, substance addictions and more, it wasn’t until I searched peer review healthcare journals to realize that a psilocybin experience may help me bridge my impasse and hopefully align my spiritual awareness by overcoming ruminations and hopefully achieving self-forgiveness. Although my psilocybin journey profoundly transformed and healed my psyche, it would be overly simplistic and even disingenuous to attribute this simply to the “mushroom.” If it wasn’t for the hours of preparation with Frank and his nonjudgmental, sincere and compassionate guidance to know about me and help me determine my journey intentions, the psilocybin experience would have been nothing more than a recreational “trip.”

During the hours of my psilocybin experience Frank was with me with, once again, mindfulness and support. Days later we met for an integration session as I described my experience, transformation and affirmations. As during the preparation sessions, Frank was nonjudgmental and embraced my journey and expressed his own joy about my attainments. I can’t emphasize enough the importance of psilocybin experience preparation and thank Frank Larson for guiding me on this journey.” (D.R.)

"Frank Larson’s non-directive approach created an environment of complete trust and freedom. He allowed me to navigate my inner landscape autonomously, without imposition or expectation. This empowered me to delve into profound insights and revelations, fostering a deep sense of self-discovery and personal growth. Frank embodies the true essence of facilitation, allowing individuals to unfold their unique journey with grace and authenticity." (C.P.)
