Compassionate Medical & Clinical Healers

Keith Heinzerling, MD

Keith is a physician board certified in Internal Medicine and Addiction Medicine and Director of the Treatment & Research in Psychedelics (TRIP) Program at the Pacific Neuroscience Institute (PNI) in Santa Monica. Prior to joining PNI, Keith was a physician and faculty researcher at UCLA and has over 20 years of experience leading research and doing clinical trials. He is a nationally recognized and published expert in Addiction Medicine and Psychedelic-Assisted Therapy. As TRIP Program director, working with Karina Sergi LMFT and Daniel Kelly MD, Keith has been Principal Investigator or Co-Investigator for clinical trials of psilocybin and LSD with upcoming trials with MDMA and 5-MeO-DMT in preparation.

Keith completed the psychedelic therapist training program and received the CIIS Certificate in Psychedelic Assisted Therapies and Research. He has guided patient treatment sessions with psilocybin and LSD and has completed several hundred ketamine-assisted psychotherapy sessions with patients. As the lead physician on the psychedelic therapy team, his priority is to maximize the safety and minimize potential risks for patients undergoing psychedelic therapy.

Keith grew up in the Angeles National Forest, went to Stanford for undergraduate and medical school, and did his medical residency at NYU and Bellevue Hospital before returning to California to study and work at UCLA. The outdoors and nature have always been a source of peace and sustenance for Keith and he lives now with his wife in the Santa Monica Mountains. His motivation in co-founding the Rewild Medicine program is to unite psychedelic therapy and nature to help patients connect with themselves, others, and the planet to better heal themselves and our environment.

Daniel F. Kelly, MD

Dr. Kelly is a practicing neurosurgeon and neuroscientist for over 25 years, and Director of Pacific Neuroscience Institute (PNI), a multispecialty neuroscience group with over 35 physicians in Santa Monica, CA. While Dr. Kelly is considered a world leader in advancing minimally invasive and endoscopic neurosurgery for all types of brain tumors, over the last 5 years, he has become increasingly involved in addressing mental health disorders with a specific interest in the potential of psychedelic-assisted therapies. He was the creative force behind the development of the Pacific Treatment & Research in Psychedelics (TRIP) program established at PNI in 2019. In 2021, he completed the Certificate in Psychedelic-Assisted Therapies and Research at California Institute of Integral Studies. In collaboration with TRIP Program Director, Dr. Keith Heinzerling, and psychotherapist Karina Sergi, TRIP has successfully completed two clinical trials with psilocybin-assisted therapy and offers ketamine-assisted therapy.

Dr. Kelly grew up in Colorado and has been a lifelong nature lover, camping, hiking and exploring the wilderness of the Colorado Rockies and California. He attended Claremont McKenna College from 1978 to 1982 and after graduating from Georgetown University School of Medicine in 1986, he completed neurosurgical training at George Washington University in 1993. He returned to Los Angeles to join the faculty of UCLA Division of Neurosurgery until 2007 when he joined Saint John’s Health Center and the Saint John’s Cancer Institute to develop a neuro-oncology and neuroscience program.

Dr. Kelly’s formative years in Colorado and California, his appreciation of the healing and grounding power of nature, and the potential synergy of nature with psychedelic-assisted therapy have led him to this collaboration with Keith and Karina in forming ReWild Medicine.
