For John Koufis, hockey has been a life-long passion. A mainstay on the adult hockey scene, Koufis has played an integral role in the growth of the game in the Chicago area.

Koufis has laced up the skates for the Chicago Sharks adult hockey team, skating with the Sharks in USA Hockey’s Adult National Championships for a number of years, including during the 2024 tournament, where the Sharks, led by Koufis, took home the 50+ Tier 1 Championship.

In addition to playing, Koufis helps manage the Sharks program, recruiting players and organizing teams to compete not only locally, but nationally as well.

Koufis represented Greece in five IIHF Division III Men’s World Championships and two IIHF Division III Men’s World Championship Qualifiers, winning a silver in 2010. Most recently, he also served as the general manager for Team Greece for the 2024 IIHF Development Cup in Bratislava, Slovakia.

Prior to the 2023-24 season, Koufis, who is the majority investor in the Tomahawks Hockey Partners, LLC investor group, purchased the Johnstown Tomahawks of the NAHL. He currently serves as the CEO and governor of the Tomahawks. 

A 1987 graduate of DePaul University with a degree in accounting, Koufis also serves as the chief financial officer at General Kinematics Vibrating Equipment.
