Greg Nunn, Ph.D., BCBA-D

Greg Nunn is a clinical/school/research and forensic psychologist, specializing in applied behavior analysis, cognitive behavioral approaches and instructional leadership. He is board certified as a behavior analyst and is a licensed clinical psychologist, with a subspecialty in neuropsychology.

Working with Nathan Azrin at Anna State Hospital (1971-1974), he designed a general psychological treatment model (HABIT REVERSAL) that has proven effective in treating a variety of anxiety-related problems, including body-focused repetitive behaviors (trichotillomania, skin picking, nail biting, etc., motor and vocal tics, Tourette syndrome, and obsessive-compulsive disorders). His work has been published in various national and international scientific journals, as invited chapters in books and as a co-authored book: “Habit Control.” Greg’s book was selected as one of the Outstanding Books of the Year in the field of behavior therapy by Psychology Today. He has also presented at state, national and international conventions.

Greg’s work in this field continues to grow in popularity and was selected as one of the Best in Behavior Research and Therapy by the editors of The Journal of Behavioral Research and Therapy in 1997. The Habit Reversal Therapy has been selected as the only empirically validated Intervention for these types of disorders. Presently, Habit Reversal Therapy has been incorporated into the Comprehensive Behavioral Intervention for Tics (CBIT) program and is promoted by the National Tourette Syndrome Association, in collaboration with the Centers for Disease Control, as an evidence-based intervention for Tourette syndrome. He was on the board of directors of the California Association for Behavior Analysis from 2004-2009, served as the co-chair of the 2006-2007 Conference Committee and was president in 2008-2009.

Greg’s interests include community development and integrated, collaborative services that can impact the breadth and quality of services available to youth and families, especially children with social, behavioral, emotional, educational, and developmental disabilities. He is particularly interested in the role that policies and practices can have on a community’s health, educational achievement, morale, productivity, and, ultimately, a community’s welfare.

Greg received his bachelor’s degree from the University of California, Los Angeles in 1971, where he worked as an undergraduate research assistant with Ivar Lovaas. He earned his Ph.D. from Southern Illinois University in 1974, with Nathan Azrin as his P.P.S. He also earned credentials in both school psychology, and guidance and counseling in 1999, and received his administrative services credential in 2005.
