As part of our Lecture Series, we were honored to host a virtual Zoom event featuring a presentation by Katie Marrotte, MSW, LCSW, on Wednesday, October 22, 2025, at 7:30 pm.
Katie, a licensed clinical social worker who specializes in the treatment of OCD, discussed the topic of Inference-Based Cognitive-Behavioral Therapy for OCD. Inference-based CBT (I-CBT) is an evidence-based treatment of choice for OCD. I-CBT is an upstream modality that targets the obsessional doubt of the OCD cycle. When the obsessional doubt is resolved, then the anxiety and compulsive aspects of OCD do not take place.
Katie is a local therapist and OCD trainer with lived experience. She believes that those suffering from OCD deserve more evidence-based treatment options than just Exposure and Response Prevention (ERP).
She has a Master’s degree in Social Work with a concentration in Health and Mental Health from the University of St. Joseph in West Hartford, Connecticut. Social work focuses not just on pathology, but also examines human development through a lens of policy, social justice, and social welfare, providing a more comprehensive view of factors affecting people on a broader scale. This background in social justice contributes to Katie’s passion for pursuing a more robust set of skills for treating OCD, as well as advocating for multifaceted treatment approaches and competency for OCD specialists.
Katie also runs a private practice (katiemarrotte.com) offering Inference-Based CBT and Exposure Response Prevention for OCD. She believes that the most effective approach for treating OCD should be evidence-based, multifaceted, and, most importantly, informed by the client’s needs.
Katie is also a co-founder of the OCD Training School, a group that offers training for treating OCD and related disorders.
