Building on a lifetime of public service, President Clinton established the Clinton Foundation on the simple belief that everyone deserves a chance to succeed, everyone has a responsibility to act, and we all do better when we work together. For more than two decades, those values have energized the Foundation’s efforts to address big challenges, create new opportunities, and make a difference in people’s lives across the United States and around the world. As an operating foundation, our programs and the partnerships we build work to expand economic opportunity, improve public health, confront the climate crisis, and inspire citizen engagement and service. The Foundation also operates the Clinton Presidential Center in Little Rock, which enhances these efforts by providing year-round educational and cultural programming and is home to the Clinton Presidential Library and Museum.
