Kate Lewis-LaMonica

Kate is a principal in Bridgespan’s New York Office. She helps lead the organization’s work with high-net worth individuals and families. Since joining Bridgespan in 2015, she has worked with a wide range of philanthropic and nonprofit clients in climate, K-12 and higher education, early childhood education, and housing and homelessness.

In her recent years at Bridgespan, she has supported several family foundations, both place-based and national, and organizations supporting philanthropy, including donor collaboratives and donor-advised funds. Her work focuses on supporting donors to structure, scale, and evolve their giving over time, often transitioning from individual generosity to sophisticated family and multi-generational giving models. She is a co-author of the articles, “Inflection Points in Family Philanthropy: Start Up, Scale Up, Tune up” (Bridgespan.org, 2025) and “How America’s Most Generous Philanthropists are Giving Big” (Bridgespan.org, 2024).

Prior to joining Bridgespan, Kate worked at the Boston Consulting Group. She also worked in DC public education for several years, leading strategy research at CityBridge Foundation— the family foundation of David and Katherine Bradley—as well at their family office. Kate earned her MBA from the Haas School of Business at University of California-Berkeley and her BA in public policy from Princeton University.
