A 19-year coaching veteran who has presided over explosive offenses during his eight seasons as a coordinator, Sean Gleason is in his first season as Kansas State’s offensive coordinator in 2026.

Gleeson comes to Manhattan from Missouri where he spent the last two seasons working with the Tiger quarterbacks. This will be his second tour of duty in the Big 12 having served as offensive coordinator and quarterbacks coach at Oklahoma State in 2019. He left Stillwater to be the offensive coordinator for three seasons at Rutgers. Prior to that, Gleeson was the offensive coordinator at both Princeton (2017-18) and Fairleigh Dickinson (2011-12).

Last season, Gleeson helped Missouri produce an 8-5 record while working with two different quarterbacks throughout the season due to injury. Those players, Beau Pribula and true freshman Matt Zollers, combined to throw for 2,444 yards and 15 touchdowns. The year prior, Missouri went 10-3, which included a win over Iowa in the Music City Bowl. The Tigers finished the 2024 season ranked fifth nationally in fewest passes intercepted (5), 10th in red zone offense (92.0%) and 16th in third down conversions (46.4%).

Gleeson went to Missouri after spending one year as a senior offensive analyst at Northwestern. It was his fourth year in the Big Ten as he spent the three previous seasons as the offensive coordinator and quarterbacks coach at Rutgers. A 2020 candidate for the Broyles Award – which is given annually to the top assistant coach in the nation – Gleeson mentored two NFL draft picks in wide receiver Bo Melton (Seattle) and running back Isaiah Pacheco (Kansas City), the latter of which was on Super Bowl winning teams in 2022 and 2023.

Under Gleeson control, Rutgers finished as the fourth-most improved team in the nation by scoring 13.4 more points per game in 2020 than the year prior to his arrival. Despite the fact that the Scarlet Knights played in three fewer games due to the COVID-19 pandemic, Rutgers scored 81 more points than in 2019, which was the sixth-best improvement in the nation. Additionally, RU was the most improved in the Big Ten in total offensive touchdowns (plus-9) in only 10 games. During his time guiding the offense, four players earned All-Big Ten honors.

Gleeson spent the 2019 campaign at Oklahoma State, helping the Cowboys to an 8-5 record – including a pair of ranked wins – and an appearance in the Texas Bowl. Under his tutelage, the Cowboy offense ranked 17th nationally in rushing offense (229.6 yards per game), 21st in total offense (453.9 yards per game) and 35th in scoring offense (32.5 points per game).

He helped guide running back Chuba Hubbard, a Consensus All-American who led the nation in rushing yards (2,094) and all-purpose yards (179.54 yards per game), while he was third in rushing touchdowns (21) and eighth in scoring (9.8). Hubbard, the 2019 Big 12 Offensive Player of the Year, eventually went on to be selected in the fourth round of the 2021 NFL Draft by Carolina.

Prior to his time at the Power 4 level, Gleeson spent six seasons at Princeton as the running backs coach (2013-15), special teams coordinator (2016) and offensive coordinator/quarterbacks coach (2017-18). Engineering one of the most explosive offenses in the FCS, he helped the Tigers to an unblemished 10-0 campaign in 2018. Under Gleeson, Princeton finished that season first in the FCS in scoring offense (47.0 points per game) and second in total offense (536.8 yards per game). Three members of the 2018 offense went on to play in the NFL in Jesper Horstad (Chicago), Stephen Carlson (Cleveland) and John Lovett (Kansas City).

Lovett, the Tigers’ quarterback, excelled as a dual-threat performer under Gleeson en route to 2018 Ivy League Offensive Player of the Year honors. Completing 66.1% of his passes with 18 touchdowns, Lovett 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, while he became Princeton’s first two-time First Team All-American since 1964.

Gleeson’s unit wasn’t only one of the best in the FCS during his time as offensive coordinator. In fact, over the 2017 and 2018 seasons, Princeton ranked fourth in the country among all FBS and FCS teams by averaging 42.6 points per game, while the Tigers ranked sixth with 509.9 yards per game.

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.

Gleeson began his coaching career at Delbarton School in Morristown, New Jersey, where he coached football, baseball and bowling from 2007 through 2010. His first job at the collegiate ranks came in 2011 and 2012 when he was the offensive coordinator and quarterbacks coach at Fairleigh Dickinson.

A native of Glen Ridge, New Jersey, Gleeson played quarterback at Williams College, a Division III program in Williamstown, Massachusetts. He was the highest-rated passer in the New England Small College Athletic Conference in 2005 with a rating of 163.6, and a year later he led the Ephs to an 8-0 mark. Gleeson received the Farley Award in 2006, 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. He also played first base for the baseball team at Williams.

Gleeson obtained his undergraduate degree in English from Williams College in 2007. He and his wife, Lauren, have three children, Eamon, Patrick and William.
