Columbia Neurosurgery is pleased to announce that Alexander Ramos, MD, PhD, a fellowship-trained endovascular neurosurgeon, is now seeing patients at ColumbiaDoctors in Tarrytown, New York, expanding access to specialized neurovascular care for patients throughout Westchester County and the Hudson Valley.

Dr. Ramos specializes in the diagnosis and treatment of conditions affecting the blood vessels of the brain and nervous system.

With advanced training in endovascular neurosurgery, Dr. Ramos offers minimally invasive, image-guided approaches to treating complex cerebrovascular conditions.

Patients in Westchester and surrounding communities can now receive specialized consultations, evaluations, second opinions, and follow-up care closer to home while remaining connected to the comprehensive resources of Columbia University Irving Medical Center and NewYork-Presbyterian.

Dr. Ramos brings extensive clinical and research experience to his practice. He earned his MD and PhD from the University of California, San Francisco, completed his neurosurgical residency at NewYork-Presbyterian/Weill Cornell Medical Center and Memorial Sloan Kettering Cancer Center, and pursued additional fellowship training at Weill Cornell. His research focuses on developing innovative techniques for delivering therapeutics to the central nervous system.

By expanding his practice to Tarrytown, Dr. Ramos is helping bring Columbia's expertise in cerebrovascular and endovascular neurosurgery closer to patients who need highly specialized care.
