The Bill & Melinda Gates Foundation (BMGF) is the largest private foundation in the world, founded by Bill and Melinda Gates. It was launched in 2000 and is said to be the largest transparently operated private foundation in the world. The primary aims of the foundation are, globally, to enhance healthcare and reduce extreme poverty, and in America, to expand educational opportunities and access to information technology. The foundation, based in Seattle, Washington, is controlled by its three trustees: Bill Gates, Melinda Gates and Warren Buffett. 

From poverty to health, to education, their areas of focus offer the opportunity to dramatically improve the quality of life for billions of people. So they build partnerships that bring together resources, expertise, and vision—working with the best organizations around the globe to identify issues, find answers, and drive change.
