Narrative of Services:

My practice consists of primarily OCD and OC related disorders. I offer state-of-the-art, empirically-based treatments for these disorders.

Training Description:

I have a PhD in Clinical Psychology from the Cognitive Behavioral Training program at SUNY at Stony Brook. I have worked at MGH for >20 years, the majority of this time in the OCD and related disorders clinic. I routinely run symposia and workshops at ABCT, IOCDF, TLC, etc. on the assessment and treatment of these disorders. I have done extensive research in the field, primarily for OC related disorders. I am on the Scientific Advisory Boards (SAB) of both the IOCDF and TLC (I chair the TLC SAB). I wrote a popular self-help book for treatment of Trichotillomania and have written many other chapters regarding treatment for OCD and other disorders. I was one of the developers of the Internet self-help programs and I am an Associate Professor of Psychology (Psychiatry) at Harvard Medical School.
