Matthew Baker, LCSW, therapist for OCD, anxiety, and PTSD in Long Beach, Los Angeles, and California

Conditions Treated: OCD, Anxiety & PTSD Therapy Online in CA

Behavioral Exposure-Based Treatment for OCD, Anxiety & PTSD

If you’re struggling with Obsessive-Compulsive Disorder, related anxiety disorders, or PTSD, you’re not alone—and effective, evidence-based treatment is available. I specialize in treating a range of anxiety-related conditions using Exposure and Response Prevention (ERP) and Prolonged Exposure (PE), approaches that are designed to help you face fears, reduce avoidance, and regain control over your life.


I work with adults, children and adolescents across California through telehealth, while based in Long Beach, Los Angeles. Whether your symptoms show up as intrusive thoughts, panic, compulsions, or avoidance, treatment is focused on helping you respond differently to uncertainty and discomfort—so you can move forward with more freedom and confidence.
