Lauren González (she/her/ella) has spent her career moving through classrooms, afterschool programs, and leadership roles, always anchored by the belief that learning should be joyful, a little messy, and full of wonder. She began in school operations at 18, from processing lunch applications and greeting families at the front desk to leading afterschool programs and teaching mixed-age groups at a local daycare. She went on to teach middle school ELA in Brooklyn before returning to Miami to chair a 6-12 English department. At every stage, her work has been about helping young people see themselves as capable, curious learners who can find magic in the process.
A proud Miami native and daughter of Cuban immigrants, her upbringing was shaped by a culture of family, resilience, and possibility (she’s also fluent in Spanglish!). Lauren will soon become the first in her family to earn a doctoral degree, completing her Ed.D. in Applied Learning Sciences at the University of Miami this December.
Teaching sparked a lasting passion for curriculum design that invites empathy, play, and rigor into the learning process. Her experience bridges classroom instruction, school operations, and program leadership, giving her a broad perspective on how to create environments where students feel safe to take risks, explore, and grow.
In 2025, Lauren joined Mizzen’s Strategic Innovation & Product team as the Manager of Educational Solutions to help bring bold, engaging resources to educators across the country. For her, the work is about opening doors, sparking curiosity, and showing students that learning can be a lifelong adventure.

She lives in South Florida with her partner, Matt, and their dog, Chopper. Outside of work, you might find her leading a spin class, browsing the farmer’s market for fresh finds, getting lost in a novel, tending to her garden, or belting Disney songs completely off-key (Chopper is her biggest fan).

Ridgway White (he/him, él) became president of the Mott Foundation in 2015, as the Flint water crisis was still unfolding.

The Urban Land Institute Michigan and University of Michigan recognized the project with their Development/Redevelopment of the Year Award in 2014.

White is a graduate of Hobart College, where he studied architecture, economics and urban planning. He serves as chair of the board of directors of U.S. Sugar and also serves on the boards of the Council of Michigan Foundations, Council on Foundations, The C.S.
