Oncology Alliance

Oncology Alliance was a prominent independent oncology practice network based in the Midwestern United States, primarily serving the Wisconsin and Florida regions. The organization provided comprehensive cancer care services, including medical oncology, hematology, radiation oncology, and access to clinical trials. At its peak, it was one of the largest community-based oncology groups in the Midwest, operating multiple treatment centers and collaborating with major research networks. In 2013, the company was acquired by 21st Century Oncology (now part of GenesisCare), integrating its clinical operations into a larger national network of cancer care providers.
