The Orange County Anxiety Center was founded to help individuals through both direct clinical services and research. Additionally, we act as a hub of knowledge and experience to help local clinicians seeking information on anxiety disorder treatment. OCAC was created by Dr. Curtis Hsia as a result of his love for his specialty and the countless patients he has encountered who spent too much of their life receiving insufficient treatment.

Here at OCAC we use empirically supported treatments tailored to each individual to help overcome anxiety and related disorders. In addition to providing clinical services, we stay heavily involved in the community and the field of psychology. The clinicians at OCAC frequently give pro bono lectures to local schools, parent teacher associations, churches and professional groups, and offer a monthly support group. We are dedicated to contributing to the body of knowledge through which therapy is improved. As such, we continue to engage in research and actively publish and presents findings at national and international conferences.

Please feel free to contact Dr. Hsia for a free consultation.
