Charles Best is the CEO and founder of DonorsChoose.org, the leading platform for giving to public schools. Charles launched the organization in 2000 out of a Bronx public high school where he taught history for five years. Teachers across America use the site to create projects requesting resources their students need, and donors of all sizes give to the projects that inspire them. To date, teachers at 82% of all the public schools in America have created classroom project requests, and over 3 million supporters have given $800 million to those projects.
