Dr. Jeff McNairy, Psy.D., M.P.H., is the Chief Medical Officer of Rythmia, the world's first and only medically licensed ayahuasca retreat, in Costa Rica. He holds a doctorate in psychology and a master's in public health from UCLA, and he ran locked psychiatric units in Pasadena before serving as administrative director of Passages Malibu, the celebrity luxury rehab. Frustrated that the Western model could stabilize patients but rarely heal them, he tried plant medicine himself in 2014 and changed course. For more than 25 years he has worked at the intersection of Western psychology and indigenous medicine, and at Rythmia he has guided 23,000+ guests through a medically screened ayahuasca protocol with a six-month 98% transformation rate. He also leads Rythmia's licensing with the Costa Rican Ministry of Health and is working to expand the model to new locations globally.
