Sarah Catherine Oltmann, MD $$

Pediatric Endocrine Surgeon

Associate Professor at UT Southwestern Medical Center

UT Southwestern Pediatric Group


Sarah Oltmann, M.D., is an endocrine surgeon at Children’s Health℠ who uses minimally invasive techniques to treat disorders of the thyroid, parathyroid and adrenal glands. Dr. Oltmann uses her experience as a thyroid cancer survivor to help patients know what to expect.

Dr. Oltmann earned her medical degree at Texas Tech University. She then trained as a general surgery resident at UT Southwestern where she also completed a research fellowship in the Division of Pulmonary Vascular Biology in the Department of Pediatrics. She then received advanced training in endocrine surgery through a fellowship at the University of Wisconsin.

Dr. Oltmann’s clinical research interests include the kinetics of intraoperative parathyroid hormone monitoring, expansion of surgical indications in thyroiditis, surgical management of hyperthyroidism, improving patient experience after thyroid and parathyroid procedures, and surgeon decision-making regarding surgical approach to adrenal lesions.

Dr. Oltmann is a member of the Society of Surgical Oncology, the American Thyroid Association, and the American Association of Endocrine Surgeons. She also is an ad hoc reviewer for the Journal of Surgical Research, Annals of Surgical Oncology and the Annals of Surgery, among other prestigious journals.

“With endocrine procedures, I know my patients will start feeling better rapidly after surgery, without a prolonged recovery time – which is not always the case for other surgical procedures,” Dr. Oltmann says. “When incision size can be decreased and safely achieve the same result as traditional options, the patient’s recovery is easier. That’s something I strive for with each procedure.”
