A continued tradition of excellence

The Division of Endocrinology, Diabetes and Metabolism at Tufts Medical Center (Tufts MC) is home to a team of exceptional endocrinologists, proud of our legacy of innovation and dedicated to providing the best patient care possible. Because the endocrine system controls many different body functions, endocrine dysfunction can contribute to an enormous range of illnesses affecting virtually every organ system of the body. 

Our goal is to understand the basis of these diseases and the endocrine system through research, develop more effective treatments and provide the highest standards of care to improve the lives of patients with endocrine disorders. We are also committed to passing on our knowledge and expertise to generations of future physicians through our Gerald J. and Dorothy R. Friedman Fellowship Program. 

Staff physicians work closely with referring primary care physicians as well as other subspecialty services including Surgery, Neurosurgery, Ophthalmology, Radiology, Nuclear Medicine, Nutrition and Podiatry to coordinate the diagnosis and management of complex endocrine diseases, including: 

  • Pituitary and hypothalamus diseases 
  • Adrenal disease 
  • Islet cell tumors 
  • Diabetes 
  • Lipid disorders 
  • Thyroid disease, including thyroid cancer and thyroid nodules 
  • Osteoporosis and other bone diseases 
  • Hyperparathyroidism and other calcium disorders 
  • Obesity 

We accept patients referred by physicians and individuals who seek help directly.

Training + education

Mission 

The mission of the subspecialty Training Program in Endocrinology in the Division of Endocrinology, Diabetes, and Metabolism at Tufts MC is to provide fellows with the knowledge, skills, attitudes and experience required for all of the competencies needed to function successfully as independent consultants in endocrinology. 

Fellows receive training in a nurturing environment of belonging that allows them to plan and develop their careers in alignment with established and emerging approaches, including digital care, while emphasizing thoughtfulness, forward-thinking and imagination toward high-quality, high-value and patient-centered care that celebrates individuality. This program is designed for fellows whose focus will be clinical practice, those who wish to become clinician-educators and those who want to pursue careers in clinical and basic endocrine research, including careers in the industry. 

Number of fellows 

To ensure close interaction among the fellows and faculty and enhance the educational experience, the program has 4 fellows each year. There are 2 first-year fellows and 2 second-year fellows. Occasionally, a fellow may have elected an educational pathway that includes additional years of training in research (third or fourth year).
