My experience with treating OCD:

My passion is helping those with OCD maximize their quality of life. OCD is debilitating, but I know that receiving the appropriate treatment can bring back your life. I’ve been a licensed therapist for over 30 years. I graduated from the University of Maryland, and have specialized training in Exposure and Response Prevention (ERP) therapy.


About Me

You may have learned that OCD can be extremely time-consuming and takes away your energy. The obsessions and compulsions cause significant emotional distress as it interferes with your day-to-day responsibilities and relationships. OCD is also treatable, and with the right guidance, you can learn to manage it. I can teach you how. It brings me great joy when people tell me how far they’ve come in such a short period of time using ERP therapy. People have said that I conduct sessions with compassion, understanding and acceptance. As your therapist, I will be here to support and encourage you through the entire process. Together, we can overcome your OCD.

Mary was very detailed in her explanation of what ocd is and how the therapy works. She used great examples and analogies to explain.

Just when my OCD has me feeling like there is no way out, she brings hope (without reassurance) to help me get through it
