Peter Barach, PhD

Clinical Psychologist

Welcome! I work with adults and couples. My clinical specialties are the treatment of people with depression, anxiety, panic attacks, PTSD, and dissociative disorders. I often work with work with adult survivors of abuse or other traumas. I’ve been with Horizons since 1985.

I have a relational and experiential approach to therapy. That means that your emotions and other responses during our appointments are pathways to changing patterns of thinking and acting that block you from getting what you need or want. I’m trained in using clinical hypnosis, EMDR, and techniques of Gestalt therapy.

I am currently seeing clients only by telehealth. You’ll need a computer with a webcam or a smartphone, as well as privacy for your appointment times.
