Monnica T Williams, MA, PhD, ABPP, Psychologist in Mansfield Center
I provide research-based treatment for anxiety disorders, including obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD). I use Exposure and Ritual Prevention (ERP) for OCD, and supervise other therapists using these techniques. I help couples in distress and offer family counseling, especially when a family member suffers from major mental illness. I also work with people struggling with ethnic identity issues. I have published multiple research papers on anxiety disorders and conduct trainings at national conferences. I am on the Scientific Advisory Board of IOCDF and BTTI Faculty. I am a member of ABCT, ADAA, and APA.
Much of my practice is devoted to the treatment of OCD, including phobias, checking, sexual obsessions (HOCD), health anxiety, hoarding, and unwanted thoughts. I use behavioral techniques to achieve rapid results. I also work with people who want to improve the quality of their relationships.
I am licensed to practice psychology in three states. I studied at MIT, UCLA, and University of Virginia. I was a professor at the University of Pennsylvania, where I trained under Dr. Edna Foa, and am I currently faculty in the Department of Psychology at the University of Connecticut.
