Mario Dominguez got hooked on racing when his father took him to the 1986 Formula 1 Grand Prix at the Autodromo Hermanos Rodriguez in Mexico City. He's been a force to be reckoned with in Champ Car since 2002.
Fluent in Spanish and English, he also speaks some Italian and French. Dominguez spent one year at Culver Military Academy in Indiana as a part of his high school education. He marched in the inauguration parade for George H.W. Bush in 1989 as a member of the Black Horse Troop.
