America’s best-known practitioner of youth gender medicine is being sued

JOHANNA OLSON-KENNEDY is among the most celebrated youth gender-medicine clinicians in the world. She has been the Medical Director of the Center for Transyouth Health and Development at Children’s Hospital Los Angeles (CHLA), one of the first high-profile American youth gender clinics and presently the largest, since 2012. A frequent expert witness in court cases who is often quoted in the media, Dr Olson-Kennedy also leads a $10m initiative funded by the National Institutes of Health to study youth gender medicine—by far the largest such project in America. In addition, she is the president-elect of the United States Professional Association for Transgender Health.
