Early life and education

Norcross was born in 1957 at Cooper University Hospital in Camden, New Jersey, the son of George E. Norcross, Jr. and Carol C. Norcross. He and his three brothers, George Norcross III, Congressman Donald Norcross, and attorney Philip A. Norcross, were raised in Pennsauken and Merchantville, New Jersey.

He earned a B.A. in psychology from Rutgers University (magna cum laude), followed by an M.A. and Ph.D. in clinical psychology from the University of Rhode Island. He completed his clinical psychology internship at the Brown University School of Medicine.

Career

Norcross joined the University of Scranton faculty in 1985, progressing from assistant professor to associate professor and professor before being named Distinguished Professor.

He holds clinical professorships in psychiatry and behavioral sciences at SUNY Upstate Medical University and clinical sciences at Geisinger Commonwealth Medical College.

He also served as a research fellow in the University of Rhode Island Self-Change Laboratory early in his career.

Norcross has been elected as president of the American Psychological Association Division of Psychotherapy, the Society of Clinical Psychology, the Society for the Exploration of Psychotherapy Integration (SEPI), and the International Society of Clinical Psychology.

Research

Norcross has been involved in research on therapeutic relationships and personalizing psychotherapy. His work with colleagues has led to meta‑analytic summaries that describe how therapists can personalize treatments to individual client characteristics, such as culture, attachment style, preferences, coping preferences, and stage of change, to optimize therapy effectiveness.

Norcross's scholarship concerns behavior change, both within and outside of formal psychotherapy. He has published on the processes by which individuals initiate, sustain, and relapse in change efforts, drawing on the transtheoretical model and systematic studies of populations attempting self‑change.

Norcross's research also encompasses psychotherapy integration, an area that seeks to unify diverse therapeutic approaches by identifying shared mechanisms and principles of change. His edited volumes and handbook chapters elaborate ways to integrate specific ingredients of different therapies with common‑factor processes, proposing principle‑based models supported by empirical research.
