Zach Hahn Steps Down, Announces Full Retirement From High School Coaching

Zach Hahn announced his resignation March 5 and called the move a "full retirement from high school coaching" after 12 seasons leading Center Grove's boys basketball program and compiling a 176-118 record, the most coaching victories in school history.

The decision follows the Trojans' season-ending 45-32 loss to Southport in Class 4A Sectional 12 at Mooresville, which Hahn cited as the final game of the season. Hahn framed the resignation as a deliberate step away from the high school sideline rather than a midseason departure or an interim move.

Across his 12 seasons at Center Grove, Hahn coached 24 players who went on to play college basketball, and his tenure produced seven Johnson County Tournament championships. Program records set under Hahn include a 16-game consecutive win streak and the best regular-season mark in school history, a 20-2 campaign in 2022-23.

Hahn placed the coaching exit in the context of a longer run in the sport. "This isn’t just a resignation; it’s a full retirement from high school coaching. Over the last 23 years as both a player and a coach, I have experienced every emotion possible. I believe that is the point of life: to feel deeply and to make an impact. I hope I accomplished both. [...] Center Grove has been a blessing for my family. I am profoundly thankful for the opportunity to serve this community and this basketball program. I hope we provided some fond memories during the cold winter months. I am excited to take a step back, let life slow down, and enjoy the little things before they aren’t ‘little’ anymore."

Hahn’s 176-118 ledger and the collection of tournament trophies and college-bound players leave a clear statistical legacy for Center Grove. The Trojans' 20-2 regular season in 2022-23 remains the high-water mark in the program book, and the 16-game streak is the longest run of consecutive wins recorded during his tenure.

With the Trojans exiting at Mooresville after the 45-32 sectional loss to Southport and Hahn stepping away from high school coaching, Center Grove closes a chapter that produced measurable milestones: 176 wins, 24 collegiate players, seven Johnson County Tournament titles, a 16-game streak, and a landmark 20-2 season. The program will move into the offseason without Hahn on the bench and with a roster and record book shaped by his dozen years as head coach.
