About Us

The clinicians at the OCD & Anxiety Program of Southern California, located in Los Angeles, deliver individualized evidence-based treatment for individuals struggling with Obsessive-Compulsive Disorder (OCD), anxiety disorders, Obsessive-Compulsive Spectrum Disorders, phobias, and depression. The therapists specialize in Cognitive-Behavioral Therapy (CBT), particularly Exposure and Response Prevention (E/RP), which is considered to be the gold standard for the treatment of anxiety and related disorders. The treatment team also utilizes other effective treatment interventions, such as mindfulness and Acceptance and Commitment Therapy (ACT). Additionally, in the Fall of 2023 and Spring of 2024, our entire treatment team was also trained in delivering Bergen 4 Day Treatment and in using the effective treatment techniques that are used in that treatment format.

Most recently, in the Fall of 2023 and Spring of 2024, our entire treatment team was also trained in delivering Bergen 4 Day Treatment and in using the effective treatment techniques that are used in that treatment format.

Patients and staff work collaboratively. The cognitive-behavior therapist and patient design the treatment plan together and then work to implement it in realistic situations. Home visit options are also available. By engaging in treatment in real life settings the therapists maximize treatment effectiveness and build confidence in the individual to maintain treatment gains post discharge.

We offer Outpatient and Intensive Outpatient Services:

  • The Intensive Outpatient Programs are designed for clients who are either unable to access outpatient treatment or are not benefiting from their current outpatient treatment.
  • The Outpatient Clinic at the OCD & Anxiety Program of Southern California provides diagnostic and treatment consultations, and evidence-based individual CBT for children, adolescents, and adults.

Part of the OCD & Anxiety Program of Southern California’s mission is to advance treatment outcome research in the field of anxiety disorders. These findings demonstrate that our clients, in general, benefit greatly from receiving treatment in our treatment programs that are designed to fit their individual needs.

Clients Testimonials

Before the four treatment days in June each day was about surviving, now each day is about living.

When I heard about the Bergen 4-Day Treatment I didn’t believe it was possible – after all, I had lived with my OCD for 14 years and had been through years and years of different therapies. During the four days I was challenged, but never forced and gave 100% effort to battle my OCD. After four days in 2015 my life and my childrens’ lives have been changed forever. I have just one word: magical.

This program has been amazing and life-changing for me. All of the therapists are amazing, thoughtful, kind, and incredibly talented.

The Bergen 4-Day Treatment has finally set me free! I have struggled with anxiety and OCD for nearly 20 years and in 4 days this team has helped me break the cycle and really take my life back. I have learned that my OCD is not me, and that I have the power to live my life on my terms without being controlled by symptoms. I will forever be grateful for this treatment and my new OCD-free life!

June 1st was my first day out of the Bergen 4-Day OCD Treatment and my world has gone from a grayscale of predictable despair to bright beautiful technicolor in literally four days

I’m a doctor and I have suffered from OCD since I was a kid. Four days with the OCD team in 2014 changed my life. Since then I have been able to complete my training as a cardiologist, and I have followed their research and been part of their Scientific Advisory Board. All I can say is: If you suffer from OCD and get the opportunity be a part of the Bergen 4-day treatment: Take it!
