Personal: The son of three-time Olympian Greg Massialas, Alexander became the youngest athlete ever to win a men's foil Division I National Championship at age 16 in 2010 -- a year after competing on his first Senior World Team at 15. Alexander grew up watching fencing and says that when his father started the Massialas Foundation, he decided to take up the sport at age seven.
Not only was Alexander the youngest member of the men's U.S. Olympic Fencing Team in 2012 at 18-years-old, but he was the youngest male athlete from any sport on the team. The anchor of the U.S. Men's Foil Team, Alexander led the squad to a silver medal at the 2013 Senior World Championships -- the first medal ever for the U.S. Men's Foil Team at the event. At the 2016 Olympic Games, Alexander became the first U.S. man to win two medals at the same Games since 1904, earning a silver in the individual competition and a team bronze. He also became the first U.S. foil fencer to win an individual silver medal at the Games since 1932.
Alexander credits his coaches with being the greatest influences on his fencing career: "My father has been there throughout my whole career. He and my other coach, Dean Hinton, have been there for every step."
