Mt. San Antonio
As a freshman and sophomore at Mt. San Antonio College, Hageman played football, as a placekicker and a punter, and competed in track and field. As a football player, he was named first-team all-conference and recorded a long field goal of 43 yards, making 19 of 20 attempts alongside 54 of 56 PATs.
San Diego State
As a junior, Hageman transferred to San Diego State, where he started all thirteen games as the placekicker and three also as the kickoff specialist. His 20 field goal makes (from 25 attempts) broke a SDSU school record, and he was a perfect 37/37 on PATs (only three prior SDSU kickers have made more PATs without a miss). He was named the Most Valuable Special Teams Player after the season.
As a senior, Hageman was named to all-MWC preseason first-teams by Phil Steele, Athlon Sports, ESPN, and other publications. He started all 14 games for the Aztecs, making all 57 of his attempted PATs and 17 of his 22 attempted field goals. Though San Diego State's website noted that he "can also punt if need be", Hageman never recorded a punt during his two years with the team.
In his 27 games with the Aztecs, there were only six in which he never recorded a point, and nine in which he recorded more than 10 points.
