My experience with treating OCD:

I’ve been practicing as a licensed therapist for over twenty five years. My main area of focus is OCD with specialized training in Exposure and Response Prevention (ERP) therapy. I use ERP to treat people with all types of OCD themes, including aggressive, taboo, and a range of other unique types.


About Me

Is your anxiety from unwanted thoughts getting in the way of your life and relationships? Are your obsessions putting a limit on your daily happiness? You shouldn’t have to live this way.I specialize in helping individuals break free from OCD and their struggles with anxiety using Exposure and Response Prevention (ERP) therapy. I want you to own a new way of seeing yourself while facing your worries about the world. Let’s work together so you can enjoy life and relationships again.
