Charles Best leads DonorsChoose.org, a nonprofit website which enables anyone to help a classroom in need. Charles launched the organization in 2000 at a Bronx public high school where he taught history for five years. To date, teachers at more than 80% of all the public schools in America have created classroom project requests on DonorsChoose.org, and more than 3 million people have given to those projects. DonorsChoose.org is one of Oprah Winfrey's "ultimate favorite things" and made the cover of Fast Company as one of the "50 Most Innovative Companies in the World," the first time a charity has received such recognition. In this episode, we talk with Charles about the trajectory and evolution of DonorsChoose.org, Charles’ advice on leadership and advocacy, and DonorsChoose.org’s partnership with NAESP.
