Who We Are

Our History

The Sant Foundation was founded as a private foundation in 2015 to complement the ongoing work of The Summit Foundation, which had been created by the same founders in 1991, as well as the founders’ personal charitable interests following the wind-down of The Summit Fund of Washington.

In addition to its grant making activities, the foundation seeks to build a portfolio of financial investments that align with the programs and ambition of the Summit Foundation. The Sant Foundation expects that it will ultimately combine with the Summit Foundation.
