Dr. Hershman worked at Four Winds Hospital, a private acute-care psychiatric hospital, in Katonah, New York where he was first a therapist and then a Program Director for over 25 years.

From his early work experience in Pediatrics at St. Luke’s Hospital Dr. Hershman developed an interest and expertise in treating individuals dealing with trauma, illness and loss, and conducted research into the psychological concomitants of injury in adolescents. His work at Four Winds with often severely traumatized patients has enabled him to study how issues of attachment impact each of our relationships and how to use this knowledge to improve people’s relationships with others and with themselves.

Dr. Hershman treats couples dealing with many relationship stressors including blended families, infidelity and divorce, as well as co-parenting. His knowledge of adoption has allowed him to help birthparents, adoptive parents and adoptees deal with the complicated issues of the adoption triangle. Dr. Hershman was part of a panel discussion on the Impact of Adoption on Young Children for the Adoptive Parents’ Committee and co-led a workshop on Introducing Adoption to Children Ages 1-6 for a New York State Adoption Conference sponsored by the Westchester County Adoptive Parents Committee. He has made numerous presentations to community organizations on the effect of loss on children, learning disabilities and the need for structure in raising children and teenagers.

Dr. Hershman uses a variety of treatment approaches including Family Systems therapy, CBT, DBT and psychodynamic therapy depending on the particular needs of a patient. He attends workshops and training seminars to enhance his skills in each of these methods. He practices both short and long-term treatment when indicated.
