Jim Mastrich

Jim Mastrich operates from a straightforward conviction: people already know what they want for their lives, and therapy works best when it clears the path between a person and that knowledge. A Licensed Psychologist based in Kingston, New Jersey, he draws on decades of private practice to bring the concrete, results-oriented tools of sport and performance psychology into everyday clinical work — applying the same discipline an athlete uses to cut through distraction to help adults and adolescents quiet the noise, including the compulsive pull of a phone that never stops demanding attention, and get back to what actually matters to them.

His practice spans two poles of human experience: the treatment of addiction — alcohol, drugs, and other compulsive behaviors — and the cultivation of peak performance across athletic, academic, creative, and professional pursuits. He works with teenagers and young adults, couples, men, and women navigating issues that range from anxiety and substance use to career transitions, relationship communication, and self-esteem.

Mastrich has authored several books on character development, codependency, parenting in dysfunctional family systems, and athletic integrity. Across all of it, his measure of real progress is less about what someone stops doing and more about the honesty, directness, and self-awareness they step into. Online sessions are available.
