Biography - Catherine A. Dinauer, MD

Catherine Dinauer, MD, is a pediatric endocrinologist who cares for patients from newborns to young adults. She specializes in pediatric thyroid disorders, including hypothyroidism, hyperthyroidism, thyroid nodules, and thyroid cancer, as well as general pediatric endocrinology disorders such as pituitary, adrenal, and growth problems. 

“I love getting to know my patients and their families over time, and watching children with complicated disorders grow up and become healthy young adults,” says Dr. Dinauer. “Endocrinology involves helping children reach their full potential in the setting of chronic or underlying disease processes, and I enjoy the intellectual challenge involved in that. It’s like solving a puzzle, putting together symptoms, growth patterns, the physical exam, and lab and imaging findings to make a diagnosis.”

Dr. Dinauer says Yale offers children with endocrine disorders the best of all worlds, providing them with a multidisciplinary team that includes pediatric and endocrine surgeons, radiologists (with expertise in pediatrics, ultrasonography, and nuclear medicine), and pediatric and endocrine pathologists. 

Before joining Yale Medicine, Dr. Dinauer was an attending physician at Walter Reed Army Medical Center in Washington, DC, and assistant chief of the department of clinical investigation at the Uniformed Services University of Health Sciences in Bethesda, MD. She was a co-author on the American Thyroid Association’s Management Guidelines for Children with Thyroid Nodules and Differentiated Thyroid Cancer, published in 2015.
