Director, Center for Minimally Invasive Endoscopic Spinal Surgery

Albert Telfeian, MD, PhD, leads the endoscopic spine surgery program. A world-renown leader in endoscopic spinal surgery with national and international patient referral base, has been also appointed as the Director of newly established Center for Minimally Invasive Endoscopic Spinal Surgery at Rhode Island Hospital/Brown University. He is board certified by The American Board of Neurological Surgery and is an Associate Professor of Neurosurgery at The Warren Alpert School of Medicine at Brown University. Previously he was an assistant professor of neurosurgery at Children’s Hospital of Philadelphia and associate professor of neurosurgery at Texas Tech University Health Sciences Center.

Dr. Telfeian also serves as Vice Chair for Quality Improvement to improve the quality of care for patients.

He is a graduate of the MD/PhD program at The Warren Alpert Medical School of Brown University and completed a postdoctoral fellowship at Yale University and his neurosurgical residency at the Hospital of the University of Pennsylvania. He also completed fellowship training in spine and functional epilepsy surgery at Switzerland’s Centre Hospitalier Universitaire Vaudois and a pediatric neurosurgery fellowship at Children’s Hospital of Philadelphia.

Dr. Telfeian has published extensively in the areas of epilepsy, functional and spine surgery and is currently involved in the research and development of ultra-minimally invasive endoscopic techniques. He was the recipient of the American Association of Neurologic Surgeons Stereotactic and Functional Neurosurgery Research Award, the American Epilepsy Society Young Investigator Award, and the J. Kiffin Penry Pediatric Epilepsy Award, and was named one of the nation’s 15 leaders in neurosurgery in the October 2011 edition of Newsweek.
