Welcome to Long Island Neurosurgical Associates
Dedicated to Exceptional Pediatric and Adult Neurosurgical Care
Long Island Neurosurgical Associates (LINA) serves as the Pediatric Neurosurgery Division for Cohen Children’s Medical Center, part of Northwell Health. Our surgeons provide advanced care for infants, children, adolescents, and adults, combining surgical precision with a compassionate, family-centered approach.
We understand how overwhelming it can be when a child or any loved one needs neurosurgical evaluation. Our mission is to offer clarity, support, and world-class expertise every step of the way. From initial consultation to treatment and recovery, we work closely with families, pediatricians, neurologists, and referring physicians to deliver the highest standard of care.
Long Island Neurosurgical Associates, P.C. (LINA) was incorporated in 1973 and has since grown into one of the most established and respected neurosurgical practices in the New York region. Over the course of its history, 14 neurosurgeons have been part of LINA, reflecting a long legacy of clinical excellence, leadership, and service to the community.
