Jack Pransky, Ph.D., has been involved with the Three Principles since 1991; his primary teachers Syd Banks, George Pransky and Roger Mills. Prior, Jack had worked in the field of Prevention since 1968, had been conducting prevention trainings all around the U.S. and authored the book, Prevention: The Critical Need, the first book to translate the research about what worked to practical application.

Once exposed to the Three Principles his entire approach changed to prevention from the inside-out. After leaving the Prevention field Jack established The Center for Inside-Out Understanding (formerly, NorthEast Health Realization Institute,) where he conducted Three Principles trainings and consultations internationally, which then also evolved into individual counseling and coaching.

Jack authored nine well-respected books on the Three Principles, including Somebody Should Have Told Us!, which many practitioners recommend as one of the best introductory books on the Principles; Seduced By Consciousness, which, along with Somebody…, many people have told him changed their lives; Modello: A Story of Hope for the Inner-City and Beyond, which won the Martin Luther King Storyteller’s Award for the book best exemplifying Dr. King’s  vision of “the beloved community”; Parenting from the Heart;  Hope for All; and Paradigm Shift about the history of the Three Principles.

Among these are two coauthored children’s books and a curriculum for middle school students.

Jack is now semi-retired but runs mentoring groups and is a coach of coaches and trainer of trainers.
