For fellow tennis pros, Andre Agassi an example off the court, too-- for philanthropic endeavors that include $550m partnership for charter schools.
"These days, everyone who's anyone in tennis — and some who struggle to fit that description — has established a charitable organization. They range from little-known players such as doubles specialist Eric Butorac to household ones such as Maria Sharapova and Novak Djokovic. Whether directly or from afar, it's not a stretch to say most were influenced by Agassi. He's the pied piper of giving back and a role model for athletes across an array of individual and team sports." -- Douglas Robson, USA Today
