Brian Leslie Weiss (born November 6, 1944) is an American psychiatrist, hypnotherapist, and author who specializes in past life regression.

[8] Dr. Weiss was astonished and skeptical when Catherine began recalling past-life traumas that seemed to hold the key to her recurring nightmares and anxiety attacks.

His skepticism was eroded, however, when she began to channel messages from her spirit guide/Master who made remarkable revelations about Dr. Weiss’s family and his dead son.

[10] Weiss advocates hypnotic regression as therapy, claiming that many phobias and ailments are rooted in past-life experiences whose acknowledgement by the patient can have a curative effect.

[11] Weiss lives with his wife Carole in Miami, Florida, where he writes and conducts public seminars and workshops on the subject of reincarnation.
