Nerissa Ko, MD, MAS
Professor
Neurology
School of Medicine

Burns School of Medicine at the University of Hawaii, and completed a residency in neurology, followed by fellowships in neurocritical care and vascular neurology at UCSF. She is board certified in both vascular neurology and neurocritical care. In 2002, she joined the UCSF Neurovascular Service, where she is now assistant director and a principle attending at Moffitt-Long hospitals.

Dr. Ko sees patients for consultation on an outpatient basis as well for stroke and complex vascular diseases such as brain aneurysms and arteriovenous malformations.
