Mark R. Treegoob PhD

I have specialized in anxiety disorders in children ages 9-17, adults, and older adults for many years. About 30% of my practice is working with OCD and growing.

I was trained in undergraduate psychology at George Washington University, and did my graduate training at Indiana State University. I did a post-doctoral fellowship at the Devereux Foundation in Devon, PA. I have treated OCD patients for at least twenty years.
