I’m a psychologist specializing in the treatment of OCD, PANS/PANDAS, anxiety, hoarding, panic attacks, and school avoidance. I work with children, teens, and adults, offering personalized, supportive care to help each person feel more in control and confident in managing their challenges.
I use CBT/ERP, an active, results-driven approach that provides significant symptom relief, often more quickly than traditional "talk" therapy. This method is particularly effective for issues like OCD, hoarding, and anxiety. As a specialist, I can resolve long-standing challenges in fewer sessions than a more general treatment approach.
Unlike larger treatment centers, I handle every aspect of patient care—from the initial screening and scheduling, to coordination with other healthcare providers. This hands-on approach allows me to deliver the highest level of personalized care. My commitment to you and your family is reflected in the quality of service I provide.
