Wisconsin Emergency Medicine expert witnesses are board-certified physicians practicing in Level I trauma centers in Milwaukee and Madison, rural critical access hospitals, and urgent care networks across the state. They often hold faculty roles at institutions like the Medical College of Wisconsin and UW Health, with subspecialty experience in trauma, toxicology, pediatric emergencies, and prehospital care. Their opinions address standards of emergency care, triage decisions, diagnostic timing, stabilization, transfer protocols, and outcomes in both urban and rural Wisconsin settings.
