Brian Leslie Weiss serves as an American psychiatrist and hypnotherapist known for shifting his professional focus toward past life regression. Since 1980, he has documented clinical work involving patients who describe previous existences under hypnosis, a practice he posits provides curative relief for modern anxieties, persistent phobias, and emotional trauma that standard clinical methods fail to address.
Academic Background
Born in New York City in 1944, Brian Weiss pursued traditional medical training. He earned a degree from Columbia University in 1966 before completing his studies at the Yale School of Medicine in 1970. His clinical credentials include an internship in internal medicine conducted at the New York University Medical Center and a two-year residency in psychiatry back at Yale University. He later ascended to the position of Head of Psychiatry at the Mount Sinai Medical Center in Miami.

The transition in Weiss's career originated in 1980 with a patient identified as Catherine. While under hypnosis, she began recalling details of previous lives, which Weiss initially viewed with skepticism. He began verifying these accounts against public records, claiming the accuracy of these details influenced his shift toward believing in the survival of human personality after biological death. He asserts he has facilitated regressions for over 4,000 patients throughout his career.
Therapeutic Theories and Authorship
Weiss advocates for regression therapy, arguing that psychological ailments often originate in past-life occurrences. His written body of work explores reincarnation, future life progression, and communication with beings he labels as Masters, or nonphysical souls. He frequently hosts seminars and workshops across the United States to instruct attendees on self-regression meditation. His publication history includes titles such as Many Lives, Many Masters, Only Love Is Real, and Same Soul, Many Bodies.
Professional and Personal Collaborations
Living in Miami, Florida, with his wife Carole, Weiss has integrated his research into a variety of formats, including meditation CDs and oracle card decks. His daughter, Amy E. Weiss, collaborated with him as a co-author on the 2012 book Miracles Happen: The Transformational Healing Power of Past-Life Memories. He also partnered with Doreen Virtue in 2014 to publish a deck of Past Life Oracle Cards.
