About Us

Governance

Asante Health Network’s governance structure includes a Board of Managers, a Quality Committee and a Finance Committee. Members of these committees reflect a blend of our independent and employed physicians and other health care leaders. They are recognized thought leaders who have a long-term vision for the health and prosperity of the communities we serve. There are ongoing opportunities for physicians and administrative leaders to participate in AHN governance.
