Dr. Stephen B. Moss, PhD


I thoroughly enjoy providing friendly, down-to-earth, and goal-focused counseling. Using forthrightness, knowledge, humor and hope, my connections to my clients is deep, committed and 24/7. No matter how badly mental health, addiction, family trauma, or various life circumstances have trapped individuals or couples in a dark place, I firmly believe that recovery and health is almost always attainable. We as a profession have the tools it takes to help people address their issues and find their paths to their “healthiest self.” Being part of this process makes my clinical work a true joy. As a senior psychologist, I am comfortable treating most mental health disorders and all addictive disorders. Professionally, I have also consulted to the federal government, state governments, and published several books and articles.

Whom I Treat

I have substantial expertise and a passion for treating all addictive disorders. This is surely rooted in my sister’s long-ago struggle with and ultimate death from heroin addiction. Recovery is always possible; act now to get help! More specifically, I treat adults and teens with alcohol problems, opiate addiction, marijuana dependence, and any other drug addiction. Additionally, I treat sexual addiction, compulsive gambling, videogame addiction, and most other behavioral addictions.

I also specialize in providing marriage and couples counseling, and also working with teen and young males “in trouble. With couples, I generally focus on building trust with both partners; improving communication skills; building conflict resolution capabilities; enhancing emotional and sexual intimacy; and helping couples recover from recently discovered addiction or infidelity. With male teens and young adults, I strive to build trust, address untreated mental health or substance abuse problems, improve family relations, build motivation for improving life success, and improve their motivation to become their “healthiest self.

More generally, being a clinical psychologist with decades of experience, I very much enjoy and am highly competent flexibly helping most adults and teens understand and treat their depression, anxiety, bipolar disorder, ADHD, or other mental health or life disorders.


Professionally, I’ve had a highly diverse career. Along with decades of counseling experience, I directed statewide services in Massachusetts, provided consultation to the federal government and all 50 states, and wrote a handful of influential health policy books. I am now fortunate to own and manage a mental health group practice, the Moss Group, that helps hundreds of children and adults on an ongoing basis.

My Offer To You

No matter how dire your circumstances, change, recovery, and health is possible. You are not alone; know that you can get help. Allow me to help you “become your healthiest self.”
