It was a privilege speaking with Prof. Diamond whom I managed to interview just before the COVID-19 pandemic (I think we all have an idea of the effect that had on all of us).  Prof. Diamond is a Pediatric Urologist with particular interests in Disorders of Sexual Differentiation, Transgender Surgery and Medical Ethics. He attended Princeton University and received his medical degree from the University of Rochester School of Medicine and Dentistry, and undertook his surgical residency at the University of Vermont and his urology residency at the Johns Hopkins Hospital. He then travelled to the UK for pediatric urology fellowships at the Alder Hey Children’s Hospital in Liverpool,  Great Ormond Street Hospital and Institute of Urology in London. His first faculty position was at the University of Massachusetts Medical School where he rose to Professor. He then joined faculty at Boston Children’s Hospital, Harvard Medical School, and remained for 25 years serving as Urologist-in-Chief for the last nine, before returning to the University of Rochester Medical Center in 2021. He has authored the definitive chapters in the last four editions of Campbell-Walsh’s textbook of Urology. He served as Clinical Ethicist and member of the Ethics Advisory Council at Boston Children’s Hospital in 2002, became Co-Director of the Gender Management Service (GeMS) at Boston Children’s Hospital in 2007, and in 2017 Co-Director of the Gender Surgery Center, the first transgender surgical program based at a children’s hospital in the US.
