Leonsis was born on January 8, 1957, in Brooklyn, New York. Born to a family of working-class Greek immigrant parents and grandparents who were mill workers, who worked as a waiter and a secretary. When his high school guidance counselor evaluated his skill set, the counselor concluded that young Ted was destined to work in a grocery store. Leonsis also reflects on his working-class roots that being a grocery store manager was all his dad aspired him to be. During his youth, Leonsis mowed lawns for extra money. One day when mowing, he stumbled upon mowing the lawn owned by a wealthy stockbroker and Georgetown alumus named Jim Shannon. Impressed by Leonsis, he helped Leonsis gain admission into Georgetown University.
