    About Tonja S. Duvardo, Psy.D.

    I am a clinical psychologist with over 20 years of experience specializing in treating adults in inpatient as well as outpatient clinical settings. My work is based on the belief that that people want to be happy, effective and successful in their lives and that they have within themselves the resources to achieve these goals. I believe that psychotherapy can help individuals most effectively use their resources to increase self-understanding, to improve decision-making, to solve problems, and to create paths to the lives they want.
