He grew up in Illinois, and later in Vernon, Connecticut, where he graduated from Rockville High School, a public secondary school. He has credited his interest in politics to his eighth grade social studies teacher, Jim Tyler, who "inspired him to work for social and political change during the tumultuous year of 1968." He was class president for three years at Rockville High School and hosted a weekly pick-up basketball game at his house, "a tradition that continues today."Warner graduated from George Washington University (GWU), earning his Bachelor of Arts in political science in 1977.

He went on to serve as Dodd's senatorial campaign manager during his freshman year of law school. When his parents visited him at college, he got two tickets for them to tour the White House; when his father asked him why he didn't get a ticket for himself, he replied, "I'll see the White House when I'm president."Warner then graduated from Harvard Law School with a Juris Doctor in 1980 and coached the law school's first intramural women's basketball team. Warner then took a job raising money for the Democratic Party based in Atlanta from 1980 to 1982.
