Clinical Services at Rush Epilepsy Center Team
Clinical Team

The Epilepsy Center at Rush University Medical Center in Chicago, Illinois, has a multidisciplinary staff that includes epileptologists (physicians specializing in epilepsy), neuropsychologists, physiologists, pediatric and adult neurosurgeons, clinical nurse specialists and social workers. Together, they develop treatment plans to address all aspects of epilepsy as it affects patients — medical, social and psychological — as well as the practical problems of daily life.

Our neurology team is on the leading edge of advances in medicine, whether it's a new minimally invasive technique or a novel drug. Because Rush is an academic medical center, our patients benefit from all of the latest innovations, including some that are unavailable anywhere else in the world.

The neurology program at Rush University Medical Center  is considered among the nation's best. Our Epilepsy Center staff includes the following experts:
