About Mary

Mary Harrington’s expertise lies in health care programs and policies for low-income families and uninsured people. She has evaluated primary care transformation, Medicaid and Children’s Health Insurance Program (CHIP) coverage reforms, and impacts on safety net delivery systems. She is highly skilled in using qualitative and quantitative methods to evaluate policies and assess implementation experiences.

Harrington’s experience includes leading a large team studying the experiences of primary care practices in transforming how the practices deliver care under the Comprehensive Primary Care Plus initiative. She is also evaluating an initiative focused on helping safety net providers prepare for value-based payment and care arrangements as well as a state Medicaid waiver program to improve oral health outcomes among children.  

Previously, Harrington led a congressionally mandated evaluation of CHIP that included a large 10-state survey of CHIP and Medicaid enrollees and disenrollees, case studies in the same 10 states, and a census survey of state CHIP program administrators. Her other experience includes directing a study to recommend options for monitoring the impact of coverage expansions on safety net providers and several evaluations of Medicaid managed care programs, including two that examined safety net provider strategies for coping with managed care and other delivery system changes.

Harrington has published her work in peer-reviewed journals and produced numerous policy pieces and briefs. She completed coursework and candidacy requirements in health services organization and policy from the University of Michigan’s School of Public Health and holds an M.P.P. from the University of Michigan’s Ford School of Public Policy.
