Sarah Oltmann, M.D., is an Associate Professor in the Division of Endocrine Surgery in the Department of Surgery at UT Southwestern Medical Center. She is an endocrine surgeon who uses minimally invasive techniques to treat disorders of the thyroid, parathyroid, and adrenal glands.

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

After receiving her B.A. in biology at Baylor University and her M.D. at Texas Tech University, Dr. Oltmann 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.

Following her fellowship training, Dr. Oltmann joined the faculty of the University of Wisconsin as a clinical instructor. She returned to Dallas in 2014 to join the UT Southwestern faculty.

Among Dr. Oltmann’s many professional activities, she is a member of the American College of Surgeons, the American Thyroid Association, and the American Association of Endocrine Surgeons. She is an ad hoc reviewer for the Journal of Surgical Research, Annals of Surgical Oncology, and the Annals of Surgery, among other prestigious journals.

In 2019 and 2020, Dr. Oltmann was named a Texas Monthly Super Doctor Rising Star.

Meet Dr. Oltmann

As an endocrine surgeon at UT Southwestern Medical Center, Sarah Oltmann, M.D., is specially trained to treat cancers and other disorders of the thyroid, parathyroid, and adrenal glands that require surgery. Her minimally invasive techniques not only reduce the size of the incision and resulting scar, but also decrease swelling and numbness for patients after surgery, resulting in faster recovery.

“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,” Dr. Oltmann says.

For patients with endocrine diseases such as hyperthyroidism, symptomatic thyroiditis, or functional adrenal nodules, surgery is often the preferred treatment because of its rapid result – immediate resolution of symptoms such as hormone overproduction (though some medical preparation prior to surgery is often necessary).

When procedures are performed using minimally invasive techniques, patients are often able to go home the same or next day and resume their normal activities within a week.

“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,” she says.

“Every patient is unique, as is their experience with surgery. I strive to prepare each patient for what surgery will entail, and for what recovery will be like.” 

As a thyroid cancer survivor herself, Dr. Oltmann uses her experience to better help patients know what to expect. She says that when she was a patient preparing for own operation, she found speaking to other patients set her mind at ease. “Reading about it in a book or on a blog is different from speaking to someone in person who has been in your shoes. I hope I can provide that comfort to my patients.”
