My Approach to Helping

“What happened to my happy child?” Parents often come to me feeling overwhelmed and confused by their child’s obsessive compulsive disorder (OCD) or anxiety. Often it starts with a small fear – about something bad happening to Mom or Dad, about getting sick, about failing a quiz – but the anxiety grows over time and keeps your child from the calm and joy you wish for them. Your child may retreat and avoid people and situations that used to bring them happiness. Many parents do their best to help them regain control of their thoughts and emotions, but they become disheartened when their efforts seem to make no difference.

The good news is we can stop OCD and anxiety from being in control. Proper assessment and therapy can help you understand your child’s difficulties and provide manageable steps towards healing. Beyond practical tools, clients and their families develop a new stance towards their anxiety or OCD that allows them to feel confident facing future challenges. Following therapy, I often hear parents say, “I never understood how all the pieces fit together until now,” or a child or teen tell me, “I didn’t think I’d feel this way again.”

Facing our fears is challenging work - if this was easy, you would’ve done it already! I will be with you along the way, providing support, humor, validation, and encouragement - and, of course, to celebrate your child and family’s big and small steps towards relief.

More Info About My Practice

I am a Licensed Clinical Psychologist who specializes in child and adolescent anxiety and OCD treatment and assessment. I received my B.A. in Psychology from Williams College and my Ph.D. in Clinical Psychology from UCLA, where I trained at the UCLA Child and Adolescent OCD Program. I then completed my Predoctoral Internship at UCSDRady Children’s Hospital and my Postdoctoral Fellowship at the UCSD School of Medicine.

I am passionate about providing evidence-based care for anxiety and OCD for youth and families in San Diego and for helping other professionals bring these treatments to the families they serve. I provided consultation for clinicians in the Rady Children’s Hospital Anxiety and OCD Clinic, and I have led workshops and invited lectures for mental health providers and psychiatrists at SDSU, Rady Children’s Hospital, and UCSD. I have also served as Clinical Supervisor at Rogers Behavioral Health San Diego and Los Angeles.
