Biography

Biography

Growing up in Spain and Mexico, Ximena Lopez, M.D., spent a great deal of her time hospitalized for severe asthma. That experience informs her daily work as a physician.

“I was impressed by the physicians who took care of me, and I have wanted to be one ever since,” she says.

Dr. Lopez focused her studies on the endocrine system, the collection of glands and organs that produce and regulate hormones in the bloodstream to control many functions of the body, including metabolism, growth and sexual development.

“Most endocrine conditions can be successfully treated, and that is extremely gratifying,” she says.

Dr. Lopez joined Children’s Health℠ in 2010 and quickly established herself as an advocate for gender diverse and transgender children and adolescents. These individuals might suffer from gender dysphoria, the distress that arises from having a gender that is not consistent with the gender assigned at birth.

Dr. Lopez founded the GENder Education and Care, Interdisciplinary Support (GENECIS) program at Children’s Health in 2015. It is the first such program in the Southwest that provides comprehensive mental and endocrine care for youth with gender dysphoria.

Management of children with gender dysphoria is complex and requires a collaborative focus, as well as an intricate attention to detail. Dr. Lopez finds her work captivating.

“I am constantly inspired by my patients and their families,” she explains. “It is extremely gratifying to see a child who is depressed blossom and become a happy individual with the adequate support and treatment.”

Dr. Lopez has participated in more than 40 international, national and local presentations as speaker on this topic, including a TED Talk.

In addition, Dr. Lopez is the principal investigator for a study evaluating the changes in psychological outcomes in adolescents with gender dysphoria followed in the GENECIS program, most of whom are on endocrine therapy.

Dr. Lopez earned her medical degree from Universidad La Salle in Mexico. She completed her pediatric residency at the University of Illinois at Chicago in 2005; her pediatric endocrinology fellowship at Massachusetts General Hospital and Harvard Medical School; and her clinical research fellowship at Joslin Medical Center and Harvard Medical School in 2008.

She is certified by the American Board of Pediatrics and its Board on Pediatric Endocrinology, and is a member of the American Academy of Pediatrics, the Pediatric Endocrine Society and the World Professional Association for Transgender Health.

She is also an associate professor of pediatrics in the Pediatric Endocrinology Division at UT Southwestern.

Outside of her practice, Dr. Lopez enjoys family activities outdoors with her son, husband and dog. She likes to go hiking and looks forward to opportunities to travel and explore new places.
