Our Clinical Psychologists


Our clinicians spend over 10 years before they join our practice specializing in evidence-based, cognitive-behavioral treatment for anxiety, depressive and behavioral disorders. You will receive the top of the line and most evidence-informed treatment currently available.

Seeing a specialist vs a generalist will be visible in the results you receive. Treatment takes a shorter time (research shows around 3-6 months vs 2-3 years) and will last longer (5-10 years or more).
