The Wisconsin Stroke Net (WSN) is based at the University of Wisconsin, Madison focusing research efforts on stroke prevention, treatment, and recovery. WSN is comprised of adult and pediatric vascular neurosurgeons, neurologists, endovascular surgeons, neuroradiologists, anesthesiologists, physiatrists, emergency physicians, and research specialists. Over 30 health care entities from throughout the region and serving diverse populations are represented within the WSN.
