Maura LeBaron-Hsieh

Maura LeBaron-Hsieh

Director of Development

Since joining our team in 2019 as Sonrisas’ Director of Development, Maura works with our grant funders, private donors, and the community at large to build awareness about Sonrisas’ work and to grow our impact over time. Her dedication to community-building and creating access to opportunity for those in need drives her work for Sonrisas. Maura holds a B.A., Harvard University, an M.P.H, University of California, Berkeley and was formerly Millbrae Education Foundation Board President. With a background in public health and health care management, Maura has extensive experience in health care program planning, implementation, and measurement. Immediately prior to joining Sonrisas to expand our Development efforts, Maura led her local Education Foundation, a 501(c)3 nonprofit funding educational equity. Maura lives in San Mateo County with her family, greatly outnumbered because even the dog is a boy. She has been hooked on Mad Libs since elementary school, treasures the opportunity to donate to worthy causes, and relishes travel, whether real or by book.

“I joined Sonrisas because I wanted to make a difference by combining my public health and fundraising experience, but I didn’t know much about the oral health care access gap in San Mateo County. Now that I’ve been with the organization for a while, two things stick with me: the incredible need for our services, and the gift of being able to connect with others who would like to share their resources to build a better future.”
