Dr. Lucy Marcil

Pediatrician. Social Entrepreneur. Policy Advisor. Speaker.

Dr. Marcil creates innovative solutions buffering kids and their families from the adversity faced growing up in poverty. Her motivation for this work is rooted in her own childhood experience with financial strain 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 a decade pioneering Medical-Financial Partnerships and leading national efforts to study the impacts of and scale this work.
​
She co-founded and is the Executive Director of StreetCred, which integrates evidence-based, underutilized economic resources into routine prenatal and infant health care; it has returned >$10 million in economic resources such as tax credits, food supports (SNAP, WIC), and paid family and medical leave, to over 3000 families in Boston. She also founded and is the Executive Director of the Health by Wealth Collective (HxWC), a national open-source, technical support community scaling medical financial partnerships; it supports 35 health centers and systems in 11 states and D.C. HxWC partners have collectively returned $35 million in tax refunds to >20,000 families. 
 
In 2023-2024, Dr. Marcil worked on federal family economic and maternal-child health policies in the Office of the Democratic Whip, Rep. Katherine Clark (D-MA) as a Robert Wood Johnson Health Policy Fellow at the National Academy of Medicine. Internationally, she has led pediatric health-systems innovation and strengthening in Namibia, Bangladesh, and Kenya.
