Overview

Summit Charitable Foundation Inc., operating as The Summit Foundation, was established in 1991 by Roger and Victoria Sant. Roger Sant is Chairman Emeritus and co-founder of AES Corporation, an international power utility. Both founders have committed to The Giving Pledge, pledging to give away at least half of their wealth to philanthropy. In 2023, the Sant Foundation merged with The Summit Foundation, consolidating their philanthropic efforts.

The foundation is a multigenerational private family foundation committed to promoting the health and well-being of the planet—its people and its natural environment. Currently led by President Lex Sant (who has served as trustee since 1991 and president since 2018), the foundation distributed over $9.3 million in grants in 2023 across 118 awards. The foundation pursues its mission through three distinct programme areas: Equality for Women and Girls, Resilient Mesoamerican Reef, and Sustainable Cities.
