Dr. Jeffrey Greenfield

Dr. Jeffrey P. Greenfield is a board-certified pediatric neurosurgeon at Weill Cornell Medicine and NewYork-Presbyterian Hospital, where he holds the position of Vice Chairman of Academic Affairs and Associate Professor of Pediatric Neurosurgery. He is the creator and director of the Chiari CARE Program — an internationally recognized multidisciplinary program caring for patients with Chiari malformation, tethered cord, syringomyelia, craniocervical instability, CSF leaks, and hydrocephalus from childhood through adulthood. He is a leading voice in the concept of transitional neurosurgery: treating congenital conditions across the full arc of a patient's life. Dr. Greenfield directs the pediatric skull base surgery, epilepsy surgery, and spasticity surgery programs. He specializes in minimally invasive endoscopic approaches, intraoperative brain and spine mapping, and complex spinal cord conditions including myelomeningocele and spinal dysraphism. As co-director of the Children's Brain Tumor Project at Weill Cornell Medicine, he leads active research into the tumor microenvironment, tumor immunology, and precision medicine for rare and inoperable pediatric brain tumors. His lab completed the first-ever genomic sequencing of a gliomatosis cerebri tumor in 2011. He is co-author of Common Neurosurgical Conditions in the Pediatric Practice: Recognition and Management (Springer) — a textbook built for primary care providers. Dr. Greenfield trained at Amherst College (magna cum laude, Neuroscience), Weill Cornell Medical College (MD/PhD), NewYork-Presbyterian/Weill Cornell (residency and chief residency), and The Children's Hospital of Philadelphia (fellowship).
