In 1975, John Kehoe went to live in the forests to study and comprehend the internal mechanisms of the human brain for three years away from civilization. Drawing information from a wide variety of scientific and spiritual sources, as well as relying on personal observations and experience, Kehoe developed his first simple and very successful program for the development of brain power. In 1978, on the basis of the developed principles, he began to educate people, and by 1980 his lectures had enjoyed tremendous success around the world. Keho has been teaching for the past twenty years. He and his wife currently live on the Pacific Northwest coast, continuing to publish books and give lectures.
