The Health Care Systems Research Network (HCSRN), formerly the HMO Research Network, is led by Executive Director Sarah Greene. She is the first-ever Executive Director of the HCSRN, and is responsible for all strategic and operational activities as overseen by the HCSRN Governing Board.  The all-volunteer Board operates as a democratic constituency, guided by a set of agreed upon bylaws.

Together, these visionary leaders are helping shape the future of the HCSRN and health systems-based research.
