About Pediatric Neurosurgery

In 2020, Weill Cornell Medicine Pediatric Neurosurgery, directed by Dr. Mark M. Souweidane, merged with the pediatric neurosurgery program at Columbia University. Dr. Souweidane now co-directs the combined program along with Dr. Neil Feldstein of Columbia, and the joint NYP Pediatric Neurosurgery program extends to all NewYork-Presbyterian campuses, including NYP Queens and NYP Brooklyn Methodist. Drs. Souweidane, Greenfield, and Hoffman also treat patients at Memorial Sloan Kettering Cancer Center. In short, if your child needs a top pediatric neurosurgeon in New York City, chances are you will be seen by one of our doctors.
