Emile Allen, M.D.

Boca Raton, FL

Dr. Allen, a retired urological surgeon, is a leading expert in the use of Advanced Clinical Hypnosis to facilitate the resolution of emotional and physical conditions. Based on his observations both as a surgeon and a hypnotist, he has developed a profound belief in the ability of the subconscious mind to heal the body.


His proven methods are founded on the principle that chronic emotional and physical conditions are the result of unresolved emotional traumas that are trapped in the subconscious mind, and therefore, consciously unknown. Through the skilled application of his proven techniques, coupled with the patient's desire to heal, Dr. Allen has helped improve the quality of life for people worldwide who have exhausted all other treatment options.


Dr. Allen is the former Chief of Urology and Vice Chairman of Surgery at Scripps Memorial Hospital-La Jolla, California. Throughout his career, he saw the power the subconscious mind had in helping his patients and their family members cope with emotional and physical crises.
