University Neurosurgeons are involved in all aspect of neurological care, including brain and spine surgery. The conditions we treat include aneurysms, AVMs, epilepsy, tumors and Parkinson's disease. Neurosurgeons also specialize in minimally invasive approaches to spinal stenosis, disc herniation and other degenerative spine conditions. Our neurosurgeons collaborate with neurologists, neuroradiologists, critical care nurses and other specialists to address the full scope of problems affecting the brain, spine and nervous system. The highly skilled multidisciplinary team at Rush provides compassionate, personalized care in what are often complex situations, and dedicates itself to enhancing patient care through research both in the lab and in the clinic and education. Recent additions to our neurosurgical staff demonstrate our commitment to innovation, collaboration, growth and excellence.
