About Us

Our Practice

We apply the science of psychology in assisting individuals and families in the pursuit of their goals. We strive to maximize their happiness and to help them live more effective lives. We work with individuals, couples, and families of any race, ethnicity, religion or sexual orientation. We have experience with all age groups including children, adolescents and adults.

We use a cognitive behavior therapy model, which teaches our patients to recognize their dysfunctional thoughts and to change them, allowing them to eventually become their own therapists. We also teach mindfulness, which is an effective treatment for many psychological problems. We have been in practice for over 30 years.

Fully licensed in Maryland, we have written many journal articles as well as having co-written a textbook on Cognitive Behavior Therapy. We were also selected to participate in the groundbreaking NIMH study comparing Cognitive Behavior Therapy to medication for the treatment of depression.
