About Dr. Klein

I am a clinical psychologist who treats individuals, families, and couples. After graduating from Princeton University, I earned a doctorate in Clinical Psychology from the University of Virginia. I completed my clinical internship at New York University -- Bellevue Hospital in New York City.
My graduate education included specialty training and practicum work in both family therapy and substance abuse. I am intensively trained in Dialectical Behavior Therapy (DBT), and received training and supervision on the use of Motivational Interviewing (MI).
I worked at Freedom Institute in New York City coordinating the DBT program, co-leading groups for adults, and seeing both individuals and families struggling with addiction and substance abuse issues.
After moving to Connecticut, I developed and served as director of the Intensive Outpatient Program (IOP) for adolescents at Silver Hill Hospital. I launched my New Canaan private practice in 2015, which is now my full time focus.
