I feel honored and privileged to have families entrust me with the care of the most precious thing they have – their children – and I take that trust very seriously.
Dr. Diesen

Dr. Diesen’s clinical interests include surgical education, clinical outcomes in general and thoracic pediatric surgical conditions and pediatric surgical endocrine disorders, such as pediatric thyroid nodules, thyroid cancer and multiple endocrine neoplasia (MENS). She treats children of all ages – from newborns to young adults – who suffer from a vast array of operable conditions, both congenital and acquired. 

“I feel honored and privileged to have families entrust me with the care of the most precious thing they have – their children – and I take that trust very seriously,” Dr. Diesen says. “It’s very gratifying to be able to treat conditions and allow children to grow up and live normal lives with normal life expectancies.”

After receiving her medical degree at The University of Virginia, she completed her general surgical training at Duke University and her pediatric surgery fellowship training at UT Southwestern Medical Center.

Dr. Diesen has been named a Top Doctor by D Magazine. She is a fellow of the American College of Surgeons and a member of the American Pediatric Surgical Association, the Society of American Gastrointestinal and Endoscopic Surgeons and the Association for Academic Surgery.  

Dr. Diesen lives in Dallas with her two shelter dogs. When she’s not working, she enjoys hiking, open-water scuba diving and traveling. She holds a private pilot’s license.
