Dan Engle, M.D.
Psychiatrist; Psychedelic-Assisted Therapy Practitioner; Author
One of the most recognized psychiatrists in the psychedelic therapy field — board-certified in psychiatry and neurology, pioneering psychedelic-assisted approaches to traumatic brain injury, PTSD, and treatment-resistant conditions.
Biography
Dan Engle is a board-certified psychiatrist and neurologist whose clinical practice at the intersection of integrative psychiatry and psychedelic-assisted therapy has made him one of the most visible physician advocates for expanded psychedelic medicine access in the United States. His background in both psychiatry and neurology is relatively rare in the field and informs his particular interest in traumatic brain injury (TBI) as a condition that may respond to psychedelic-assisted treatment.
Engle has worked with ketamine-assisted therapy, psilocybin facilitation in retreat settings, and advocacy for MDMA-assisted therapy for PTSD. His clinical work has focused on treatment-resistant conditions — patients who have cycled through conventional pharmacotherapy and psychotherapy without adequate relief — including veterans and first responders with complex PTSD and TBI. His book 'A Dose of Hope: A Story of MDMA-Assisted Psychotherapy' (2021) co-authored with Jason Good, brought the clinical story of MDMA therapy to a broad general audience through a narrative format.
Engle is a prominent speaker and media figure in the psychedelic medicine space, regularly appearing at psychedelic conferences, on major podcasts, and in documentary films. He helped found the Clinician's Coalition for Psychedelic Access to organize physicians advocating for improved patient access to psychedelic therapies. His practice, Full Spectrum Medicine, emphasizes an integrative approach combining psychedelic-assisted therapy with nutrition, exercise, sleep optimization, and mind-body practices.
