Oberlin College Athletics

Thomas Klosowski enters his third season with the Oberlin College men's lacrosse program in 2025-26 after he was named assistant men's lacrosse coach in June of 2023. He will serve as the team's defensive coordinator, face-off coach, and recruiting coordinator.

Kloswoski made his return to the NCAC known to his opponents in 2024, coaching up a defense that finished with a conference-best penalty-killing percentage of 75.8%. Klosowski's defense also excelled at forcing turnovers, with the Yeomen defense averaging over 12 caused turnovers per game, good for second in the conference and a top-thirty rank in all of Division III. Coaching a USILA All-American honorable mention in 2025, Klosowski helped the Crimson and Gold earn NCAC Coaching Staff of the Year honors and directly worked with three All-Conference honorees. 

Prior to Oberlin, Klosowski spent the 2023 season as the assistant men's lacrosse coach at Bates College. Before his time in Lewistown, Klowsowski served as an assistant coach at Kenyon from 2019-2022. During his time in Gambier, Klosowski helped lead the Owls to the NCAC Tournament each season, including runner-up finishes in 2022 and 2021. Guiding the third-ranked defense in the country in 2022, Klosowski’s rearguard led the NCAC in caused turnovers, man-down goals, scoring defense, and goals allowed.

The historic 14-win season in 2022 also featured Kenyon’s first-ever NCAC playoff win and highest finish in school history. Throughout his tenure, he helped mentor 29 All-NCAC selections, including 2022 NCAC Defensive Player of the Year Mayo Amorello. Furthermore, he instructed three USILA All-Americans and six USILA Scholar All-Americans.

Klosowski brings additional experience as a former high school and club head coach and is also the owner and operator of TK Athletics LLC (Miami, FL), an organization intended to build youth, middle, and high school developmental programs in South Florida.

The 2010 Miami-Dade Player of the Year out of Gulliver Prep in Miami, Klosowski went on to earn All-American honors at Onondaga Community College (Syracuse, NY) where he won two National Junior College Athletic Association championships. He would later play at The Ohio State University before transferring to the University of Miami to earn a Bachelor of Science in Sports Administration. 

A former member of the Polish National Team, his playing career would continue professionally as he spent time with the Florida Launch of the MLL, and he also played for the Columbus Crows of the IBLA.
