Neurosurgery and Procedures

The Department of Neurosurgery is home to the most innovative medical research and clinical practice available anywhere in Western New York. The team utilizes cutting-edge treatments for patients with disorders affecting the brain, spine, and central and peripheral nervous systems. Their participation in dozens of clinical trials and their work in the development of minimally invasive endovascular techniques - specifically in the treatment of stroke – provide patients with the best chance for positive medical outcomes.

All neurosurgeons are with University of Buffalo Neurosurgery and can be reached at (716) 218-1000 unless otherwise noted.
