Endocrinology and Diabetes Fellowship at Mount Sinai Beth Israel

The Mount Sinai Beth Israel Fellowship in Endocrinology, Diabetes and Bone diseases is usually a two-year training program encompassing all phases of endocrinology and metabolism. The Division is supported by a dedicated staff of Attending Physicians, certified diabetes educators, nutritionist and nurse practitioners. As part of the Mount Sinai Health System, the Division is closely integrated with the Mount Sinai Campus and the lead Division and all our Fellows are encouraged to participate in many joint activities.

First-Year Fellows

First-year fellows are responsible for inpatient consultations and participate in Endocrinology Clinic and Diabetes Clinic. They are exposed to a full range of endocrine and metabolic disorders, including: 

  • Type 1 and type 2 diabetes
  • Gestational diabetes
  • Thyroid dysfunction and tumors
  • Lipid Disorders
  • Obesity
  • Osteoporosis
  • Pituitary Disease
  • Parathyroid dysfunction
  • Adrenal gland hypo/hyper activity
  • Diseases of ovaries and testes
  • Fluid/Electrolyte abnormalities

During the first year of training, fellows work with a specialized Diabetes Team of physicians, nurses and nutritionists learning to provide rapid, optimal and comprehensive care to diabetic inpatients and clinic patients.  In doing so, they become familiar with the various modalities of diabetes treatment, including multiple injection therapy, insulin pumps and continuous glucose monitoring.

Second-Year Fellows

  • In the second year, fellows participate in a variety of additional experiences including the following possible rotations:
  • Pediatric Endocrinology Clinic
  • Male and Female Reproductive Endocrinology Clinics
  • Vascular Surgery
  • Parenteral and Enteral Nutrition Therapy
  • Thyroid sonography and FNA Clinic
  • Thyroid cytopathology
  • Thyroid nodule and thyroid cancer clinic at NY Eye and Ear Infirmary
  • Bone density interpretation

The remainder of the second year is devoted to a research project chosen by the fellow in partnership with a large number of potential mentors throughout the Mount Sinai Health System. This choice is best made during the first year so that a full year’s experience can be gained resulting in a useful body of work.

Academic and Educational Resources

All fellows attend various conferences throughout the academic year both at BI and on the main uptown Mount Sinai campus. These include Clinical Case Discussions, Endocrine Curriculum Conferences, Journal Clubs, multidisciplinary Endocrine and Head and Neck Surgery Thyroid/Parathyroid Conferences, Adrenal Conferences, and Pituitary Conferences.  All fellows meet with the Division Chief weekly to discuss patient cases and ongoing projects and to assess progress.
