Mike Pollio announced his retirement Tuesday after eight years as commissioner of the Mid-South Conference.
His retirement is effective July 1.
"I have enjoyed every day I have been commissioner of the Mid-South Conference," Pollio said. "The relationships I have had with the presidents, athletic directors, coaches and staff at each school make this a bittersweet decision."
A national search will be conducted to find Pollio's replacement.
"Commissioner Pollio has done an outstanding job for each of the Mid-South Conference's member schools," Campbellsville University President Michael Carter said. "He has brought a wealth of experience and knowledge to the commissioner's office. His professionalism and ability to be fair in his work across the various sports has made each of our schools stronger."
Under Pollio's leadership, MSC football grew from nine to 14 members, making it the NAIA's largest football conference. Because of its size, the conference now receives two automatic bids to the NAIA playoffs.
Pollio also developed the NAIA's only conference-run radio network and forged TV and Internet deals for the league.
Before becoming Mid-South commissioner, Pollio spent 27 years as head basketball coach at Eastern Kentucky, Kentucky Wesleyan and Virginia Commonwealth and as an assistant at VCU and Old Dominion. He also spent time as associate athletics director for external affairs at Louisville.
