It is my privilege to serve as Chief for the Division of Endocrinology, Diabetes and Metabolism. While our medical specialty is not new, our section was redeveloped in 2007. We are continuing to grow our discipline and expand our partnerships and collaborations as the fields of medicine become increasingly intertwined.

Lawrence J. Mandarino, PhD
Professor of Medicine
Chief, Division of Endocrinology, Diabetes and Metabolism


The physicians and medical professionals in the Division of Endocrinology, Diabetes and Metabolism are specially trained in the medical science, diagnosis and treatment of diseases of the endocrine system and its related conditions.

The most common concern we treat is diabetes and all its complications. These include heart disease, kidney disease, retinopathy (vision) and limb pain that are associated with this malfunction in the body’s glucose or blood sugar levels.

Other endocrine conditions our patients may face, which are handled by our team in conjunction with other specialists, include:

  • Thyroid disorders
  • Lipid disorders
  • Endocrine surgery, tumors
  • Metabolic bone disease
  • Adrenal and pituitary disorders
  • Pregnancy-induced diabetes
  • Male and female hormonal disorders
  • Hospital consultations
  • Parathyroid conditions

In addition to our clinical and educational outreach responsibilities, we train future endocrinologists and are engaged in biomedical research. See our Research webpage to learn more about topics our faculty are studying to bring you better answers for your health care needs and a brighter future.

For our patients and their families, we offer an ongoing series of free diabetes workshops and wellness educational events at the Diabetes Prevention and Education Center (DPEC), which is hosted by the Banner – University Medicine Endocrinology and Diabetes Clinic next to Banner – University Medical Center South. Although the center’s physical facilities are not open to the public during the COVID-19 pandemic, the DPEC includes a large cooking demonstration kitchen and classrooms.
