The Division of Pediatric Endocrinology, Diabetes and Metabolism performs more than 12,000 outpatient and more than 200 in-house consultations per year.We also perform more than 240 diagnostic endocrine tests per year in our Endocrine Testing Service. The endocrine team consists of 7 board certified pediatric endocrinologist, certified nurse educators, nurse practitioners, nutritionists, social worker, administrator and secretaries. We are a designated site for the NY State Congenital Adrenal Hyperplasia and Newborn Thyroid Screening Program. We have been recognized by NCQA for our quality measures in Pediatric Diabetes care. Only 1 other program in NY State has been certified. Members of our faculty were selected as a Top Doctor listed in Top Doctors: New York Metro Area 16thedition of Castle Connolly’s acclaimed guide to the top medical specialists in the New York metro area, and superdoctors, a nomination process conducted by the national research division of MSP Communications,


Program overview

The fellowship training program in pediatric endocrinology at Cohen Children's Medical Center has trained numerous pediatric endocrinologists who are presently in practice or in academic positions. This is a three-year program certified by the ACGME leading to board-eligibility for the Sub-Board Committee of the American Board of Pediatrics in Pediatric Endocrinology.

The program combines a broad inpatient and outpatient clinical experience in childhood disorders of endocrinology, as well as opportunities for both clinical and laboratory research. Some of the types of diseases the fellow encounters include: growth failure, precocious and delayed puberty, diabetes mellitus, thyroid disease, disorders of electrolyte and fluid balance, pituitary disease, bone and mineral disorders, adrenal disease, parathyroid disease, endocrine consequences of genetic disorders such as Turner syndrome, Klinefelter syndrome, and neurofibromatosis, and endocrine complications of childhood cancer. The fellow’s first 12 months are chiefly clinical.

All inpatient and outpatient encounters are supervised closely by our staff of 7 full-time board-certified pediatric endocrinologists. Fellows in turn learn to play an active role in resident and intern education. 

The fellows' research program, usually pursued in the second and third years of the three year fellowship, has included projects involving clinical trials, animal experimentation, hormone immunoassays, and molecular genetics. Fellows need not have prior experience in lab bench work to acquire these skills. They will receive instruction in commonly utilized lab tools as they apply to a particular endocrinology research project. The American Sub-Board of Pediatric Endocrinology requires that fellows complete a research project resulting in at least one first authored progress report or publication in order to be eligible to take the specialty Sub-Board Examination. 

Fellows are regularly called upon to present clinical cases, reviews of recent articles in the literature, and research-in-progress at regular intervals in rounds and conferences. Fellows also attend one or more annual meetings of medical subspecialty societies pertinent to their fellowship training in endocrinology. They also are expected to attend all regularly scheduled pediatric department didactic lectures, and have a special annual 12-week Fellows' Seminar directed at clinical trial design, reading the literature, statistics, introduction to molecular biology, and organizing a presentation or writing a paper. Twice a year, fellows are evaluated by the program director and staff. 

The high volume, the complexity of cases, the national and internationally renowned faculty, ancillary support, and the children’s hospital environment provides fellows with the best possible setting to gain the highest level of training and expertise. The skills and abilities gained through this program will provide a solid foundation to excel as leaders in the practice of pediatric endocrinology.

Program highlights

  • Pediatric Endocrine Summer School is taught by faculty and fellows to incoming first year fellows over the summer months.
  • Weekly Endocrine Conferences: Endocrine Unit offers weekly mandatory didactic conferences presented by local and other faculty. The Pediatric Endocrine team -rotating residents and students- have the opportunity to attend.
  • The Monthly Journal Club, which is open to the Pediatric Endocrine team, rotating residents and students. Recently published papers are presented and discussed, and the meetings incorporate short tutorials or learning activities to teach about different aspects of clinical research.
  • Monthly Journal Watch attended by the Pediatric Endocrine team, rotating residents and student. A member of the endocrine team presents highlights of a specific journal every month. A quick overview of the currently literature to keep the team up to date, different from the in-depth critical appraisal of Journal Club.
  • Board Review Sessions: The pediatric endocrine curriculum is reviewed over a one-year period at board review sessions held weekly with the Program Director.
  • Neuro-radiology rounds are held every 2 months: Neuro-endocrine cases are reviewed with neuro-radiologists and the endocrine team.
  • Combined Adult and Pediatric Endocrine Grand Rounds are held once a month.
  • Practice Improvement Projects. All fellows are expected to develop a practice improvement project)
  • Fellow Portfolio that includes case logs, records of clinical case conferences, journal club, abstract and manuscript submissions, practice improvement projects and records documenting training in the core competencies
  • Fellows are given opportunities to write chapters and reviews with faculty and are required to complete a research project in the second to third year of fellowship
  • Statistical courses: Multiple statistical courses (Introductory and Advanced), grant writing, research design and ethical Conduct of Research are offered by the Clinical Research Training program: Ongoing courses are offered by the Clinical Research Program.
  • Fellows also attend one or more annual meetings of medical subspecialty societies pertinent to their fellowship training in endocrinology
  • Scholarship Oversight Committees meet semi-annually for each fellow to review ongoing research, and provide expertise, research and career guidance.
  • Clinical Competency Committee: meet semi-annually for each fellow and determine the milestone level for each competency mapped to the 6 common EPAs to be examined. The CCC consists of three or more individuals, at two one of whom is based outside the subspecialty discipline


Rotations are arranged based on the personal interest of the fellow. Rotations with the adult endocrinologist’s team -including pediatric OBGYN and genetics- are available to all fellows during the course of three years. All rotations are done within the hospital and our affiliated premises including Hofstra NSLIJ School of Medicine and the Feinstein Institute for Medical Research.

Based on the fellow’s interest other rotations at an outside hospital can be arranged by the Program Director.


Our division is actively involved in multiple research protocols funded by the NIH, foundations, philanthropy and pharmaceutical companies. Faculty and fellows associated with the Pediatric Endocrinology Fellowship at Cohen’s Medical Center have published over the last year more than 15 papers in peer reviewed journals on topics including adrenal gland, fetal programming of adult disease, Cushing Syndrome, lipids in diabetes, pancreatic development, epigenetics, to name a few. Our research highlights include: phenotypic evaluation of children at risk for Metabolic Syndrome and Type 2 diabetes, initiation of new treatments for type 2 diabetes mellitus, animal studies in the field of fetal programming of adult disease and pancreatic development, endocrine disorders associated with Diamond-Blackfan anemia. Fellows have the opportunity to work in research labs of mentors within Feinstein Institute. Research mentors identify opportunities for fellows in training in grant writing, biostatistics, IRB submission, maintenance of protocol approval and scientific writing.
