Lucy Marcil is an Associate Professor of Pediatrics at Boston University and Associate Director of Economic Mobility for the Center for the Urban Child and Healthy Family at Boston Medical Center. She co-founded and is the Executive Director of StreetCred, which provides an integrated economic bundle of evidence-based, underutilized services to low-income families as a routine part of pediatric primary care in the first year of life. Her work has led to over 6,000 families claiming over $14 million in tax returns.

Dr. Marcil is nationally known for her work on improving health equity through economic justice. Her motivation for this work is rooted in her childhood experience with financial instability and her experience with patients who have expressed that having access to just a little bit of cash – to pay a bill, repair a car, find childcare – could be transformative to their financial well-being and mental and physical health. She has spent nearly a decade pioneering Medical Financial Partnerships and leading national efforts to study the impacts and scale this work, including StreetCred’s Health by Wealth Collective, an open-source technical support service that has 18 members in 10 states and D.C. For her work, Dr. Marcil has been recognized with the American Academy of Pediatrics Anne E. Dyson Child Advocacy Award, Aspen Institute Ascend Fellowship, and TED Fellowship. Her TED talk has over 1.4 million views.

Dr. Marcil completed her MD at the University of Pennsylvania, MPH at Johns Hopkins School of Public Health, and pediatrics training at the Boston Combined Residency Program (Harvard University, Boston University). Prior to entering medical school, Dr. Marcil served as a PEPFAR HIV/AIDS volunteer in the Peace Corps in Namibia.
