Experts in endocrinology, diabetes and metabolism
Our world-class team of doctors specialize in the diagnosis, treatment and management of a wide range of endocrine-related conditions, including metabolic disorders, thyroid problems, hormone imbalances and diabetes.

About us

Endocrinology is the branch of medicine dealing with a complex group of glands and hormones, their receptors, pathways and the endocrine diseases and disorders associated with those hormones. An endocrinologist is a doctor specifically trained to diagnose and treat hormone imbalance, endocrine diseases and endocrine disorders.

The Division of Endocrinology, Diabetes and Metabolism is staffed by recognized leaders in clinical endocrinology who are affiliated with the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell. The division offers inpatient and outpatient consultation services as well as ongoing management of endocrinology disorders.

Comprehensive care that’s tailored to you

Our division is highly trusted by local primary care physicians who provide their patients with comprehensive care for the diagnosis and treatment of endocrine diseases and disorders. Through our inpatient and outpatient care facilities, we offer:

  • Ultrasound-guided fine needle aspiration of the thyroid

  • American Diabetes Association-accredited diabetes education program

As members of the nation’s third largest nonprofit, secular healthcare system, our team of experts work closely with other Northwell Health specialists for special consults as needed.
