Dr Leo Sprinkle, PhD undertook pioneering research investigating the UFO abduction field in the mid-1960s and set the standard for research in this controversial field. He is a member of the American Association for the Advancement of Science, the American Association for Counseling and Development, and the Association for Past-life Research and Therapies.

As a professor at the University of Wyoming and a therapist, Dr Sprinkle conducted over 500 hypnotic regression sessions with individuals wishing to explore their possible UFO contact experiences. Among these were many of the most sensational and well-documented cases of our times. He published the book Soul Samples in 1999, featuring some of his case studies, with a focus on UFO experiences and reincarnation.

Dr Sprinkle has also published several encyclopedia entries, a half dozen book chapters and approximately 50 articles on various topics, including: UFO research, ESP, hypnosis, reincarnation, spiritual emergence, and counseling theory and practice. In 1980, Dr Sprinkle founded the Rocky Mountain Conference on UFO Investigation which ran for two decades. The conference served as a focal point and beacon of hope for hundreds of abductees/contactees/experiencers hoping to come to terms with their experiences.

He has participated in many regional and national television programs, including ABC’s That’s Incredible and NBC’s Tomorrow and has been invited to speak at numerous international conferences. Dr Sprinkle continues to have an active interest in the field of ET contact experience and related phenomena.
