In 2017, Dr. Dewey left the Feinstein Institute and moved to the Department of Psychiatry at the New York University, School of Medicine.

Dr. Dewey started an outreach program in 1994 bringing his research findings to school districts throughout Long Island and the tri-state area. His informative message has reached hundreds of thousands of school-age children, parents, teachers, administrators, and counselors. “Dr. Dewey’s message is science-based, objective, and delivered with a sense of urgency, compassion and caring that commands attention,” stated former LICADD Executive Director, Dr. Jeffrey Reynolds.
