The New Job: Head of the Dikembe Mutombo Foundation
For nearly two decades, Dikembe Mutombo was a big name (and a big man) in the world of the NBA. Over his time on the court, he racked up a number of records, including having been a eight-time all star and having lead the league twice in rebounds. At the conclusion of his career, Dikembe founded the foundation that bears his name, which offers humanitarian aid to his home country, the Democratic Republic of Congo.
