In July, Children’s Hospital Los Angeles shuttered its pediatric gender clinic, which she had long run, in the face of threats from the Trump administration. Her bio has since been added to the roster of physicians at the Gender Confirmation Center, where her team, called Prosilio Gender Care, is based in Pasadena, California.

The Gender Confirmation Center of San Francisco and Dr. Scott Mosser, a plastic surgeon who according to his own bio opened the center in 2013, were each named along with Dr. Olson-Kennedy in a lawsuit filed in December by a young woman, Clementine Breen, who received gender-transition interventions from them as a minor and later detransitioned.
