Bill Pettit has shared the Three Principles within his psychiatric practice for more than 35 years. Bill was mentored personally for over 26 years by Sydney Banks, and his direct experience with Syd’s teaching closely informs his work. 

His most recent speaking and coaching work has focused on overcoming trauma, and the understanding that there is just one cause—and one cure—for mental illness. 

Bill is board-certified in psychiatry and holds an M.D. from University of Illinois College of Medicine and a B.A. from Creighton University, and has been previously board-certified in mind-body medicine, and twice certified in addiction medicine.  He presently holds an appointment as Associate Clinical Professor in the Department of Psychiatry at Creighton University School of Medicine. 

Bill also served as a physician in the United States Navy for more than 9 years, including 3 years as a Navy Flight Surgeon and 3 years as Chief of Psychiatry of the Navy Nuclear Submarine base at Groton, Connecticut.

Since 1983 Dr. Pettit has been a student and sharer of the Three  Principles, presenting at many national and international programs and conferences, and consulting clients, individuals and organizations both locally and abroad.

Bill and his wife, Linda, now live in Phoenix, Arizona, where Bill continues to practice psychiatry two mornings a week, and devoting the rest of his time and energy sharing the Three Principles through as many avenues as possible.
