William W. Ashley, Jr., M.D., Ph.D., M.B.A., F.A.A.N.S., is a board-certified, fellowship-trained neurosurgeon.

Dr. Ashley graduated from Stanford University with a degree in biology. He earned a medical degree as well as a doctoral degree in physiology and biophysics at the University of Illinois College of Medicine. He also completed an M.B.A. in health care administration from the Loyola University of Chicago. He then completed a neurosurgical residency at Barnes Jewish Hospital/Washington University School of Medicine in St. Louis, followed by a dual fellowship in cerebrovascular and endovascular neurosurgery at the University of Illinois at Chicago Medical Center.

Dr. Ashley specializes in the treatment of all aspects of cerebrovascular disease. He uses open cranial and skull base surgical approaches and minimally invasive endovascular techniques. His areas of expertise include cerebral aneurysms, stroke, brain tumors, arteriovenous malformations, extracranial carotid disease, intracranial atherosclerosis, complex cranial base tumors (including vestibular schwannomas and pituitary tumors), tumor embolization, and balloon occlusion testing. He also treats general neurosurgical conditions such as degenerative disorders of the cervical and lumbar spine.

Dr. Ashley has authored more than 80 peer-reviewed articles, book chapters, and abstracts and acts as an editor for several national and international scientific journals. He is actively involved in basic science and translational research, and his research interests include the molecular basis for brain aneurysm rupture, cerebral vasospasm, stroke and novel neuroprotection paradigms.

Dr. Ashley is a careful and concerned physician and surgeon. His training and expertise gives him the unique ability to combine the most advanced techniques with a personalized, concierge approach to caring for all patients and their families.
