The Indiana Oncology Society (IOS)

The Indiana Oncology Society (IOS) is a powerful community of oncologists, nurse practitioners, physician assistants, and other allied health professionals who provide a voice for multidisciplinary cancer care teams and the patients they serve.

Founded in 2009 through the unification of the Indiana Medical Oncology Society (IMOS) and the Hoosier Oncology Office Practice Society (HOOPS), IOS is the largest oncology professional organization in the state. Members rely on us to provide innovative resources to help them stay ahead of the shifting healthcare landscape and challenges that directly impact the high-quality care their patients deserve-both locally and on a national level.
