A gold medal winner in 2004 and 2008, May-Treanor and teammate Kerri Walsh keep it green. Says Misty: “I do everything I can to support eco-friendly living.” The Los Angeles-native, one half of the winningest team in the history of beach volleyball, has enjoyed a prolific career. She appeared on “Dancing with the Stars” in 2008 before bowing out to injury. May-Treanor and Walsh are the only beach volleyball team to repeat as gold medalists. Maybe they’ll make that a triple in London!
