About
I specialize in IFS (Level 1), ERP, and CBT to help adults with anxiety, OCD, depression, and PTSD. Many of my clients look like they are doing well but are internally exhausted or overwhelmed. I help my clients address both the presenting symptoms and the root causes of emotional suffering. My approach is warm and calm with a touch of humor. Depending on the problem, I use exposure and response prevention (ERP), Internal Family Systems (IFS), and/or cognitive behavioral therapy (CBT). My goal is for my clients to break patterns and experience lasting change. I work with adults 18 and older and am out-of-network (superbills provided). Please reach out if you have any questions about therapy or how I can help. I offer free 15-minute consultations. Specialties: I specialize in helping adults with anxiety, OCD, and trauma Credentials & Experience: I have advanced post-graduate training in ERP, IFS, and CBT.
