Marisel Losa is a seasoned healthcare and nonprofit strategist who advises organizations navigating complex community, health, and equity challenges. With more than three decades of executive leadership experience, she helps mission-driven organizations turn complexity into clarity, alignment, and measurable results.

Throughout her career, Marisel has led nonprofits, statewide coalitions, and cross-sector initiatives focused on public and population health, access to care, and systems change. Her work is grounded in communities where culture, language, trust, and lived experience matter as much as data and policy. She brings a deep understanding of how decisions are made at executive, funding, and policy levels and how to ensure community voice is embedded, not sidelined.

She is the founder of the Florida Association of Free and Charitable Clinics, where she built a statewide provider network and secured $9.5 million in recurring public funding. She later served as President and CEO of the Health Council of South Florida, leading regional health data, strategy, and evaluation across a multi-county region.

Marisel also designed and led community data platforms, including Miami Matters and Greenwood Counts, giving leaders shared visibility into community conditions and a foundation for collaboration and accountability.

Today, through her consulting practice, Community Imperatives, Marisel serves as a fractional leader and strategic advisor to health systems, nonprofits, coalitions, and funders. Her leadership has been recognized with honors including the Robert Wood Johnson Foundation Culture of Health Prize, the March of Dimes Humanitarian Award, the Bank of America Neighborhood Excellence Initiative Local Hero Award, induction into the Miami Dade College Alumni Hall of Fame, and the Florida International University Distinguished Alumni Torch Award.
