John C. Norcross, PhD, is a professor, psychologist, and 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.
Dr. Norcross is author of over 400 publications and more than 20 books. His two self-help books are Changeology and Changing for Good (the latter with James O. Prochaska and Carlo C. DiClemente). 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 his undergraduate honors thesis on pragmatist philosophers such as William James, John Dewey, and Charles Sanders Pierce.
Among his professional books are Psychotherapy Relationships that Work, History of Psychotherapy, Leaving It at the Office: Psychotherapist Self-Care, and Self-Help that Works. He has also coauthored ten editions of the Insider's Guide to Graduate Programs in Clinical & Counseling Psychology and eight editions of Systems of Psychotherapy: A Transtheoretical Analysis (with Prochaska).
