Eric Nussbaum, MD, and Leslie Nussbaum, MD, PhD

At the National Brain Aneurysm & Tumor Center, our neurosurgeons Eric Nussbaum, MD, and Leslie Nussbaum, MD, PhD, are highly subspecialized and dedicated to treating and caring for patients with complex problems including brain aneurysms, vascular malformations, carotid artery narrowing, and complicated brain and skull base tumors. Instead of trying to do everything in the specialty of neurosurgery, we focus exclusively on these complex problems. We treat a high volume of cases and, as a result, we offer outcomes that rival the best centers in the world.

Our approach and results have garnered recognition from top centers throughout the United States and internationally. Complex cases are referred to us on a regular basis for consideration, particularly those that have failed treatment or been turned down for treatment elsewhere.
