Frank Larson, M.D.
Frank Larson graduated from medical school in 1987 and practiced as a surgeon before pivoting to psilocybin facilitation, now grateful for the opportunity to help people support their mental health through the use of psychedelics. Frank uses a mindfulness-based approach in his facilitation work and assists 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 or to reconnect with spirit.
Frank
Works Best With:
Medical & Clinical Professionals
Those with a medical or professional background who bring intellectual curiosity and health literacy to the process.
Health-Related Anxiety
Clients navigating anxiety connected to health concerns or medical experiences who are ready to explore the roots of their worry.
Complex Presentations
Individuals with a layered or challenging clinical picture who are looking for a facilitator comfortable with nuance.
Deeper Understanding
He helped gather signatures in 2020 to place Measure 109, the Psilocybin Services Initiative, on the Oregon ballot, and has participated in transformative group ceremonies led by a Mazatec healer in Mexico to deepen his understanding of plant medicines and healing. He is a member of the Central Oregon Psychedelic Society, the Psilocybin Facilitator Association, and the Psilocybin Assisted Therapy Association. He comes to this work with humility and respect — for the natural world that shares these plants, for our ability to connect with our inner healer, and for our potential to achieve inner freedom.

Customer Reviews
Really, it feels like I went to wash [away] all my negative feelings and experiences from childhood till now. It is life changing experience.
Frank created a safe environment that was based on my overall requests. Frank took the time to understand my background, my goals, and my concerns. Frank was very respectful and really made this a power and unique experience. Odyssey is a safe and wonderful guide to anyone interested in exploring their inner self beyond the traditional methods of therapy and meditation.
I was nervous about this experience, not knowing what I might find. Frank thoroughly prepared me, giving me the tools to deal with any challenges that might arise. He listened to me during the preparation phase, helped me frame my intentions in a positive light. He was calm and reassuring the day of my journey, and had the perfect playlist that was an integral part of my experience. I had both of my integration meetings now, and that really helped guide me down a path where I could get the most out of my new state of mind. I fully expect to have another journey in the future, and would love for Frank to be my facilitator again!
I feel like Frank really cared about my growth through this experience. I really value the intelligence and wisdom he brings as an MD and experienced facilitator. He really put the time in for me; our prep and integration sessions often ran over an hour and I never felt he was trying to wrap things up. Frank has become an important person in my life and I’m so grateful for that!
“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.”
"Dr. Frank’s demeanor, care, attentiveness, and communication was excellent. I feel like I hit the facilitator jackpot with Frank. This experience saved my life."
"Dr. Larson's calming presence made me feel safe before and after experience. I liked how in depth we went in our [preparation] appointments before the experience. I think the information shared with Dr. Larson helped him understand some of the feelings I was having during the experience. I also loved Bend itself, I felt very calm, safe and grounded there."
"Frank was thoughtful, kind and made me feel safe. I could tell he deeply wanted to heal and meet my goals. His authenticity made me able to be open fully to this journey. I was able to reconnect with my inner light and soul and feel the love and compassion for myself deeply become a part of my way of life."
"Frank has a lot of experience with psilocybin. He was patient. We did a good amount of preliminary work which was important because this was my first time and I was extremely nervous."
"From our initial meeting, I felt like I was in safe hands, and that sense of security only deepened with each interaction we had. Frank struck a perfect balance between being supportive and non-directive, and his sincerity and compassion were evident throughout. I’m really glad that I was able to meet with Frank the day after the session and take a walk around the river. We covered a lot of ground, literally and metaphorically, as we he helped me process and unpack the experience."
"Compassionate and professional, empathetic and grounding - working with Frank created such a deeply nurturing environment for me to expand my consciousness and process suffering. His ability to create and hold space allowed for meaningful and transcendent explorations of my psyche. I always felt safe to explore the limits of what my soul could discover through the vulnerable experience of working with mushrooms therapeutically for the first time. Never judgmental or anxious, Frank exudes a calm, welcoming energy that fueled my experience to its fullest extent."
