We are stronger together! Based in Milwaukee, Versiti Blood Center of Wisconsin (formerly BloodCenter of Wisconsin) combines the strength of blood centers in Wisconsin, Indiana, Illinois, Michigan and Ohio with state-of-the-art diagnostic laboratories, physician services, and a world-renowned Blood Research Institute. Your blood will always stay local first, but now we will have even more access to rare and unique blood types to help meet the needs of Wisconsin hospital patients in need. Together, with you, we promise to continue our mission: we are a beacon of hope.
