Pediatric Surgery Fellowship

The NewYork-Presbyterian/Columbia University Pediatric Surgery Fellowship Program is a two-year program designed to provide a broad intensive education in all aspects of pediatric general surgery. The education is focused on, but not limited to, pediatric surgical oncology, congenital and acquired conditions of the newborn, non-cardiac thoracic surgery, and all aspects of pre- and post-operative care of infants and children.

Multidisciplinary programs in Trauma, ECMO, Congenital Diaphragmatic Hernia, Oncology, Thyroid disease, Obesity and Esophageal Atresia provide focused education in these areas.  The integrated program in prenatal pediatrics provides the fellow exposure to diagnosis, treatment, and counseling of the fetal patient/family as well.

The goal of our training program is to graduate surgeons who can independently evaluate and treat the full scope of pediatric surgical diseases, manage the consequences of treatment, and know when to seek appropriate consultation and advice.
