Sean Gleeson joined the Tigers football program in March 2024 and serves as an assistant coach, working primarily with quarterbacks. He spent his first season as a senior offensive analyst before being elevated to his current role in 2025.
Gleeson came to Columbia from Northwestern in 2023. Before that, he spent three seasons with Rutgers as an offensive analyst and quarterbacks coach. While with the Scarlet Knights, he mentored two NFL draft picks, Bo Melton (Seahawks) and Isaiah Pacheco (Chiefs), and was named a candidate for the 2020 Broyles Award, which annually honors the top assistant coach in college football.
With Gleeson’s assistance, Rutgers finished as the fourth-most improved team in the nation by scoring offense (+13.4 points per game). The Scarlet Knights scored 81 more points than in 2019 (playing three fewer games), the sixth-best improvement in the nation in total points scored. Additionally, RU was the most improved in the Big Ten in total touchdowns scored (+12) and offensive touchdowns (+9).
Before his stint in Piscataway, New Jersey, Gleeson was at Oklahoma State in 2019 as the offensive coordinator and quarterbacks coach. Under his tutelage, the Cowboys' offense averaged 32.5 points (36th nationally) and 453.9 yards (22nd nationally) per game with two ranked wins and a berth in the 2019 Texas Bowl. The balanced unit (2,985 rushing yards, 2,916 passing yards) also ranked 17th in the country with 229.6 rushing yards per game and 27th with a 64.1 completion percentage. Additionally, he mentored Big 12 Offensive Player of the Year, Doak Walker Award finalist and consensus All-American Chuba Hubbard.
Gleeson spent six seasons at Princeton prior to his time in Stillwater, where he started as the running backs coach (2013-15), before adding special teams coordinator duties in 2016. In his final two seasons at Princeton, he was named the offensive coordinator and quarterbacks’ coach. Engineering one of the most explosive offenses in the Football Championship Subdivision, he helped the Tigers to an undefeated 2018 season.
Coached directly by Gleeson, Tiger quarterback John Lovett excelled as a dual-threat performer to win the 2018 Ivy League Offensive Player of the Year. Lovett, who completed 66.1 percent of his passes with 18 touchdowns, led the Ivy League by averaging 303.0 yards of total offense per game, passing for 203.7 yards per game and rushing for 99.3 yards per contest and became Princeton's first two-time first-team All-American since 1964.
In Gleeson’s six years on staff, Princeton won three Ivy League championships and averaged 36.9 points per game, which marked the program's highest output over a six-year stretch in program history. Three members of the 2018 offense went on to play in the NFL: Jesper Horstad (Bears), Stephen Carlson (Browns) and John Lovett (Kansas City).
Gleeson’s first job after graduation came at Delbarton School in Morristown, where he taught English and algebra and coached football, baseball and bowling. His first job in college football came as offensive coordinator and quarterbacks coach at Fairleigh Dickinson from 2011-12.
A native of Glen Ridge, New Jersey, Gleeson graduated from Williams College in 2007 with a degree in English. While at Williams, he was the highest-rated passer in the New England Small College Athletic Conference in 2005 with a rating of 163.6. His team finished 8-0 in 2006. He received the Farley Award that year, which is presented to the member of the football team who demonstrates superior qualities of dedication, loyalty and sacrifice for the betterment of the team. Gleeson also played first base for the baseball team at Williams.
Gleeson is married to Lauren, and they have three children, Eamon, Patrick and William.
