Pediatric Endocrinology Fellowship

Mariano Castro-Magana, MD
Program Director's Message

The hallmark of Winthrop-University Hospital's Pediatric Endocrinology Fellowship is its access to uncommon as well as common endocrine disorders. The extraordinarily challenging case mix includes relatively large numbers of Prader-Willi Syndrome patients, growth hormone deficient patients, and those with intersex problems. The relationship between the clinical disorders and the underlying genetic causes is actively pursued by fellows as they rotate between clinical practice and the Endocrinology Laboratory. Our fellowship is a model of bench-to-bedside-to-bench exploration. In this strong academic environment, pediatric endocrinology fellows are encouraged to attend both national and international conferences, where they have presented research findings. Post fellowship graduates are routinely recruited to positions in academic medical centers.



  • Approximately 400 growth hormone-deficient patients per year and approximately 200 Prader-Willi Syndrome patients per year; Prader-Willi practice is one of the largest in the country
  • Specialized expertise in the treatment of intersex problems
  • Educational focus on genetic aspects of endocrine diseases
  • Faculty internationally recognized in their areas of expertise
  • Active involvement in ongoing research in Winthrop's Endocrine and Metabolism Laboratory
  • One-on-one mentoring with a faculty that has diverse and complementary areas of expertise
  • Generous house staff benefits, including heavily subsidized housing and complimentary meals



A three-year fellowship is emphasizing clinical skills as well as basic and clinical research. The fellow participates in the care of children and adolescents with a wide range of endocrine disorders, including: growth hormone deficiency, diabetes mellitus, thyroid diseases, adrenal and gonadal disorders, ambiguous genitalia and intersex problems, abnormal pubertal development and hirsutism.
