John C. Norcross is a university professor, clinical psychologist, and board-certified specialist in psychotherapy, behavior change, and self-help.
He is Distinguished Professor of Psychology at the University of Scranton and Adjunct Professor of Psychiatry at SUNY Upstate Medical University. He also maintains a part-time practice of clinical psychology in Scranton, Pennsylvania.
Norcross is author of over 400 publications and more than 20 books. His two self-help books are Changeology and Changing for Good. His approach to therapy has been called pragmatic, inspired in part by his interest in pragmatist philosophy, an interest that dates back at least to his undergraduate years, when he wrote an undergraduate honors thesis on pragmatist philosophers such as William James, John Dewey, and Charles Sanders Peirce.
Among his professional books are Psychotherapy Relationships that Work, History of Psychotherapy, APA Handbook of Clinical Psychology, Leaving It at the Office: Psychotherapist Self-Care, Handbook of Psychotherapy Integration, and Self-Help that Works.
