2023 Board of Directors

The NAACOS Board of Directors works to advance the vision and values of NAACOS, which focuses on fostering the growth of the ACO model of care. Board members represent a diverse range of ACO interests and help shape NAACOS priorities such as educating ACOs in operational and clinical best practices, advocating on behalf of ACOs with Congress and the executive branch, and educating the public about the value of accountable care. Board members serve three-year terms and a third of the committee is comprised of newly elected members each year.
