Rees was born to Bill and Susan Rees in Los Angeles, California and grew up in Lake Bluff, Illinois. His father played college football at Ohio Wesleyan and served as an assistant coach at Northwestern and UCLA. Tommy played football at Lake Forest High School where, as a senior in 2009, he completed 215 of 308 passes for 2,572 yards and 23 touchdowns, including a 526-yard, six-touchdown performance against Bradford. His brother Danny Rees played football at UCLA. Rees was rated a three-star recruit by ESPN and Rivals.com, and signed with the Notre Dame Fighting Irish in July 2009.
College career
2010 season
As a freshman at Notre Dame, Rees saw limited action in games against Michigan and Navy, before being forced into action early against Tulsa when starting quarterback Dayne Crist ruptured his patellar tendon. Rees finished the game with 334 yards and four touchdown passes, but threw a costly interception in the waning minutes of the game which sealed the victory for the Golden Hurricane. Rees led the Irish to victories in his first four starts at quarterback, including upsets of Utah and USC, culminating in a 33–17 victory over Miami in the Sun Bowl. He finished the season with 1106 yards passing, 12 touchdowns and 8 interceptions.
2011 season
In the 2011 season, Rees passed for 2,869 yards, 20 touchdowns, and 14 interceptions. Notre Dame went 8–4 in the regular season with a bowl loss. Andrew Hendrix and Everett Golson competed with Rees for the starting QB position in the 2012 season. After Michigan's comeback in the September 10 rivalry game, the derisive nickname "Turnover Tommy" began to circulate, which stuck with Rees following his performance in 2011, and through his college career. Despite this reputation, Rees would finish the season with a completion percentage of 65.5%, a second to the Irish record of 68%, held by Jimmy Clausen. Rees' 14 interceptions this season was a tie for 11th in the FBS.
2012 season
Rees was suspended by head coachBrian Kelly for the first game of the 2012 season after the junior quarterback was arrested and charged with resisting law enforcement and illegal consumption of alcohol by a minor after fleeing from an off-campus party. Everett Golson was named the starter for the opening game against Navy in Dublin, Ireland. Golson played most of the second game of the 2012 season against Purdue but was injured leading Rees to come in. Rees entered the game to a cascade of boos yet exited after piloting the game-winning drive, which ended in a winning field goal for Notre Dame. However, after the game, Coach Brian Kelly indicated that the team was staying with their initial starter, Golson, for the third game of the 2012 season at Michigan State. Rees would go on to start two games that year as Notre Dame made the BCS title game.
2013 season
On June 5, 2013, it was announced Rees would start at quarterback for the 2013 season.
