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.

I’m a California therapist who specializes in evidence-based treatment for OCD and anxiety disorders, as well as PTSD. I provide structured, hands-on therapy and work actively and collaboratively with adults, teens and children to help them reduce unhelpful responses, face uncertainty, and make meaningful, lasting progress.
Many of the people I work with experience thoughts or images that feel disturbing, confusing, or difficult to say out loud. I’ve worked across multiple treatment settings and approach this material with openness, professionalism, and care. Together, we’ll make sense of what’s happening and move forward with a clear plan and consistent guidance.
