Oliver Luck was general manager of two World League of American Football teams before becoming president of the league, so Andrew spent his early childhood in London and Frankfurt, Germany, where he attended Frankfurt International School. He is the oldest of four children, including sisters Mary Ellen and Emily and brother Addison. Mary Ellen is a Stanford graduate who played volleyball there, Emily is a current Stanford student, and Addison lived in Morgantown, West Virginia before their father's job took him to the Indianapolis area. In London, Andrew attended The American School in London. As a result of his childhood in London, he is a fan of soccer. Although supporters of London clubs Arsenal and Tottenham have reached out to him believing he was a fellow fan, Luck said, "I try to support as many of the American fellows playing [in the Premier League] as possible. " Luck said the Houston Dynamo was the "number one team in my heart" because his father was the club's founding president and general manager.
