Gregory is recognized as a world-class speaker. He has delivered presentations and workshops across America on a variety of topics—everything from practical spirituality to mental health and substance abuse treatment and services delivery—for churches, classrooms, organizational conferences, scholastic seminars and learning groups both large and small.
Whether delivering a stand-alone talk or an extended workshop, his energetic delivery keeps audiences and participants on the edge of their seats. More than anything, he conveys complex concepts and processes with a succinct, easily-comprehended approach. Listeners often comment that the topics may be familiar, but they have come to understand it better than they ever did before.
He has been a guest on several television and radio programs including Larry King Live. In 2003, Gregory became an adjunct lecturer at the University of Tennessee College Of Social Work, teaching Human Behavior in the Social Environment and Psychopathology.
