The Association for Contextual Behavioral Science (ACBS), a more than 8,000 member international society he helped form, is large focused on work he had a roll in creating. His popular book "Get Out of Your Mind and Into Your Life" was featured in Time Magazine among several other major media outlets and for a time was the number one best selling self-help book in the United States.
