Greensboro's Thyroid and Diabetes Specialist

Welcome to Greensboro Endocrinology, the endocrinology, diabetes, and internal medicine practice of Michael D. Altheimer, MD. Board certified in internal medicine and endocrinology, Dr. Altheimer has built a reputation for providing high quality and exceptionally personalized care since establishing his practice in Greensboro, NC, in 1986. 

At Greensboro Endocrinology, we take the time to listen to your concerns. We provide state-of-the-art, evidence-based care, delivered in an individualized and compassionate manner. Most of our patients seek long-term care for diabetes, lipid disorders, thyroid conditions, and/or other endocrine and metabolic problems. Most often, this is done in the form of consultative care—working closely with your primary care physician or other referring provider. In addition, for a smaller segment of our patient population, we provide comprehensive long-term adult primary medical care with a focus on wellness and prevention. We encourage all of our patients to be well-informed and active participants in their own healthcare. Thank you for placing your trust in our practice as we partner in your care.

In order to assure the highest level of personalized service and patient satisfaction, each member of our team is carefully chosen—based on training, experience, competence, and (most importantly) a genuine caring attitude.

Greensboro Endocrinology will soon offer our patients secure, 24/7 online access to important information in their electronic medical records, as well as secure communications, through our patient portal.

Conveniently located off North Elm Street (at the first traffic light north of Cone Blvd), at 7C Corporate Center Court, Greensboro Endocrinology shares space, staff, lab, and support services with Medoff Medical, which is the established gastroenterology practice of Jeffrey Medoff, MD.

We hope you find the information on this website helpful. Please contact us with any questions, concerns, or suggestions.

Dr. Altheimer has been my endocrinologist for several years. Upon my first visit I found him knowledgeable and well informed, and he instilled in me a confidence that he could resolve my medical issues. I have been extremely pleased with my treatment and would not hesitate to continue having him as my physician.
