ThedaCare and Bellin Health in Green Bay have announced a partnership of cardiovascular services. The group will be comprised of about 50 cardiology providers covering nine hospitals and nearly 20 outreach centers across 17 counties in Northeast and Central Wisconsin and Michigan.

The partnership will have a common administrative leadership structure and allow for more specialized services.

In 2008, the organizations formed an accountable care organization, BellinThedaCare Healthcare Partners. In 2017, they formed Robin by HealthPartners, which the systems use to self-insure employees and their dependents. Robin also offers group health plans for large and small employers, as well as Medicare options and insurance plans.
