More than 400 doctors and health care professionals signed a letter addressed to two Dallas hospitals decrying the closure of the state’s only comprehensive medical program for transgender children, The Dallas Morning News has learned. Addressed to leadership at the University of Texas Southwestern and Children’s Health and sent in late November, the letter urges the hospitals to reverse course on shuttering the clinic. The News exclusively obtained the letter from sources involved in its drafting. “As Texan health care providers, we are writing to you to express grave concerns regarding recent news that there are plans to shut down the Genecis clinic, which provides treatment for transgender and gender-diverse youth,” the letter’s signers said. “The mission of Children’s Health is to make life better for children. How can this decision possibly be in line with your mission?” they asked. “The values of UT Southwestern are excellence, innovation, teamwork and compassion. How can this decision possibly be in line with your values?”
