About Sheila

Sheila Hoag specializes in health care reform and insurance coverage, with a focus on children’s coverage and access to care.

Hoag directs several notable projects that aim to increase health care coverage for children, including an evaluation of the KidsWell Campaign, an effort sponsored by the Atlantic Philanthropies to take advantage of policy opportunities afforded by the Affordable Care Act to create universal coverage for children. She also directs a study of an effort to engage city leaders in conducting outreach and enrollment for children and their families eligible for Medicaid, CHIP or Marketplace coverage, also funded by Atlantic Philanthropies. In the arena of broader health care coverage and care delivery, Hoag leads the design and implementation of the process evaluation for Enroll America, a project that aims to help the Robert Wood Johnson Foundation understand how its investments have contributed to program enrollment.

From 2011 to 2014, she directed the Children’s Health Insurance Program Reauthorization Act (CHIPRA) Express Lane Eligibility Evaluation, which evaluated approaches to encourage take-up and retention in Medicaid and CHIP; and from 2010 to 2014, was a lead researcher in the congressionally mandated evaluation of the CHIPRA 10-State Evaluation.

Before joining Mathematica in 1996, Hoag held positions in health care and private industry, including serving as a contract administrator for the University of Pennsylvania Health System. She is widely published in peer-reviewed journals such as Health Affairs, Foundation Review, and Health Care Financing Review. She is a reviewer for Health Affairs and the Journal of the American Medical Association, and served on the board of the Eastern Evaluation Research Society from 2012 to 2014. Hoag holds an M.A. in public policy studies from the Irving B. Harris School of Public Policy Studies and a certification in health administration from the Graduate Program in Health Administration and Policy, both at the University of Chicago.
