Dr. Blank is the founder and director of Riverdale Psychology. She received her M.S. and Psy.D. from The Ferkauf Graduate School of Psychology.

Using cognitive behavioral techniques and a psychodynamic conceptualization, I work with children, adolescents and adults in individual, family, group, and couples therapy providing a solution-oriented approach in a comfortable environment that enables you to successfully achieve your goals.

As a licensed clinical psychologist, I have experience treating individuals struggling with anxiety, depression, trauma, interpersonal relationships, and other life stressors. I received my doctoral degree from Ferkauf Graduate School of Psychology, Albert Einstein College of Medicine, after graduating magna cum laude with highest honors from Queens College of the City University of New York.
