Scott Leibowitz is a pioneer in the field of transgender health care. He has directed or worked at three gender clinics on the East Coast and the Midwest, where he provides gender-affirming care, the approach the medical community has largely adopted for embracing children and teenagers who come out as transgender.

He also helps shape policy on L.G.B.T. issues for the American Academy of Child and Adolescent Psychiatry. As a child and adolescent psychiatrist who is gay, he found it felt natural to work under the L.G.B.T. “umbrella,” as he put it, aware of the overlap as well as the differences between gay and trans identity.

It was for all these reasons that Leibowitz was selected, in 2017, to be a leader of a working group of seven clinicians and researchers drafting a chapter on adolescents for a new version of guidelines called the Standards of Care to be issued by the World Professional Association for Transgender Health (WPATH).
