About Us

The Division of Pediatric Endocrinology at Weill Cornell Medicine (WCM) provides state-of-the-art care for children and adolescents with diabetes and pediatric endocrine disorders. Our team, led by Dr. Zoltan Antal, incorporates the expertise of pediatric endocrinologists, certified diabetes educators, nurses, nutritionists, and a pediatric nurse practitioner. In addition, the division provides collaborative care in partnership with child psychiatrists, psychologists, social workers, and other subspecialists in the WCM Department of Pediatrics.

Office Information and Patient Forms

We provide comprehensive care for a full range of pediatric endocrine disorders, including:

  • Congenital Adrenal Hyperplasia (CAH) and other adrenal disorders
  • Type I and type II diabetes mellitus (T1D and T2D)
  • Dyslipidemia
  • Childhood obesity
  • Failure to Thrive (FTT)
  • Growth disorders
  • Pituitary hormone deficiencies (including growth hormone deficiency, diabetes insipidus and hypopituitarism)
  • Irregular menses, hyperandrogenemia and Polycystic Ovary Syndrome (PCOS)
  • Metabolic bone diseases including Osteogenesis Imperfecta (OI, brittle bone disease), McCune-Albright Syndrome (MAS), low bone mass and frequent fractures
  • Calcium and phosphorus metabolism disorders, including rickets
  • Disorders of puberty (early or delayed)
  • Sexual differentiation disorders
  • Thyroid disorders (congenital or acquired)
  • Turner Syndrome (TS)

What Sets Us Apart

  • The first nationally recognized comprehensive care center for CAH.
  • A comprehensive weight loss management program with accreditation as a bariatric surgery center.
  • Extensive experience managing complex metabolic bone diseases in collaboration with colleagues at the Hospital for Special Surgery.
  • Personalized and individualized care management plans for children with diabetes mellitus.
  • Emphasis on use of medical technology and electronic healthcare applications to improve care and communication with patients and families.

Diagnosis & Treatment

Treatments of endocrine disorders are complex and may include oral medication, daily home injections or specialized in-office injections on a recurring basis.

We also offer more detailed diagnostics if needed, including testing for growth hormone deficiency, early or delayed puberty, or adrenal insufficiency. These specialized tests are scheduled separately.

What to Expect

As an academic institution, we are dedicated to training future physicians. At most of your visits, you will find physicians-in-training as your first point of contact. They may be medical students, pediatricians who are completing residency, or endocrinology fellows who have completed a pediatric residency. They are always under the direct supervision of your primary provider, who will be present during all visits.

At all visits, a comprehensive history and examination will be performed. Because much of what we do is ingrained in growth and development, examinations often include staging pubertal development. It may help an older child, or a child who is anxious, to know that we will be examining their entire bodies (their pediatricians likely are, as well).

On occasion, blood tests, x-rays, ultrasounds or MRIs will be required for further evaluation. We offer same-day, on-site phlebotomy and simple radiology studies. However, some tests require specific timing (i.e. early morning) and others require scheduling a radiology appointment, and we may need to schedule your child's testing for a future date under these circumstances.


Weill Cornell Medicine Pediatric Endocrinology researchers engage in a wide range of research activities to expand the understanding of endocrine disorders in children and adolescents, and to innovate more effective strategies for the prevention, management and resolution of endocrine disease. We continue to break new ground in our understanding of conditions including diabetes, congenital adrenal hyperplasia, pediatric growth and metabolism.
