Margaret McKenna leads the Walmart Foundation, a perch that gives her one of the biggest jobs in US philanthropy, running the charitable efforts of Wal-Mart Stores Inc.
McKenna directs a half-billion dollars a year in giving, focusing on hunger and education. While she tackles issues close to her heart, she has also become an ambassador for the world’s most powerful retail machine, helping to burnish its image and lay the groundwork for its push into urban markets.
