Dr. Taemin Oh is the Co-Director of Complex Pediatric Spinal Neurosurgery and the Director of Pediatric Neurosurgical Scoliosis. His primary focus is guiding young patients through their surgical journey and advocating for their care. As a pediatric neurosurgeon, he has an active practice offering contemporary treatments for common neurosurgical conditions such as hydrocephalus, brain cysts/tumors, aneurysms/arteriovenous malformations, and craniosynostosis. In addition, he has specialized expertise on managing pediatric spinal pathologies, including pediatric scoliosis and spinal deformity, spina bifida, tethered cord, cerebral palsy, spasticity, Chiari malformation, and cervical deformity. He is well-versed in both traditional open surgery and minimally invasive, fusionless surgeries, including vertebral body tethering. After graduating with honors from Yale University, Dr. Oh earned his medical degree from the University of California, Los Angeles, and completed his residency in neurosurgery at the University of California, San Francisco. He is one of the few pediatric neurosurgeons in the country, and the sole one in New York City, who has dual training in pediatric neurosurgery and pediatric spine surgery, completing two highly regarded fellowships at the University of Utah and Shriner's Hospital for Philadelphia. This comprehensive training has equipped him to address pediatric patients' unique challenges. Reflecting on his expertise in pediatric spine surgery, he has a dual appointment with the Department of Orthopedic Surgery at Columbia.Dr. Oh is actively involved in research on motion-preserving alternatives to spinal fusion, such as vertebral body tethering, minimally invasive pediatric spine surgery, and spinal column shortening to relieve tension on the spinal cord in patients with tethered cord syndrome. With more than 70 peer-reviewed publications and an H-index of 32, his research is widely recognized and frequently cited in the field. His work has helped shape the direction of pediatric scoliosis care, vertebral body tethering, and other innovative surgical approaches. By combining his research with his surgical expertise, Dr. Oh is expanding access to fusionless alternatives that improve recovery and preserve mobility for children across New York and beyond. His goal is simple: to make surgery safer, recovery faster, and outcomes better for every patient he treats.
