Gary R. Spiegel, M.D. is a board-certified Interventional Neuroradiologist with CAST accreditation in Neurointerventional Surgery specializing in the treatment of brain AVMs by liquid embolic occlusion, endovascular occlusion and exclusion of brain aneurysms and emergent embolectomy and revascularization for acute stroke. He is an Associate Professor in the Department of Neurology and the Director of Endovascular and Interventional Neurology at McGovern Medical School at The University of Texas Health Science Center at Houston. He received his medical degree from McGill University in Montreal, Canada and completed his residency in diagnostic radiology at New York University Medical Center in New York City.

Dr. Spiegel is fellowship trained in surgical neuroangiography and diagnostic neuroradiology. His practice encompasses the full scope and breadth of adult and pediatric neurointerventional treatments for brain, spine, head and neck conditions, with a focus on endovascular treatments for brain aneurysms, brain and spinal arteriovenous malformations and stroke. Upon entering professional practice, he initiated and directed neurointerventional surgery programs at Yale University’s Hospital of Saint Raphael in New Haven, Connecticut, and later at Hartford Hospital, where he co-directed the Stroke Center. Dr. Spiegel’s efforts led the Hartford Hospital Stroke Center to become the most active acute stroke care and endovascular aneurysm treatment center in New England.

Dr. Spiegel has held teaching appointments at Yale-New Haven Hospital in New Haven, Connecticut, and at the University of Connecticut’s John Dempsey Hospital in Farmington, Connecticut. His clinical research efforts led Hartford Hospital to be the third leading enrolling site in the MERCI trial, establishing the first mechanical treatment for acute stroke. He has authored articles published in Neurology, Spine and Stroke and coauthored the textbook, Ischemic Stroke: An Atlas of Investigation and Treatment.

Dr. Spiegel seeks to provide exceptional clinical care to his patients and their families.
