Dorman Gymnasium is the competition home of the Peacock men's and women's basketball, volleyball and wrestling teams. Both basketball teams and the volleyball team also use Dorman Gym for their practice facility.
The building also houses the majority of athletic offices and locker rooms, the Brooke Kerns Athletic Training Room, the Jim Day Suite, the Steve & Diane Harms Conference Room, the Bob & Betty Firth Lobby, the student-athlete computer lab, the athletics weight room, as well as the Upper Iowa Athletics Hall of Fame.
The gym itself can seat 1950 fans. Dorman Gymnasium was most recently renovated in 2007 thanks to the Road to Glory Capital Campaign. The UIU Board of Trustees contributed $250,000, while the Road to Glory capital campaign raised an additional $119,967. The changes to Dorman included renovations of the Football Locker Room (including new wood lockers), the Bob & Betty Firth Lobby, the Harms Conference Room, the relocation of the Wrestling Room to the upper level of the Rec Center, as well as upgrades to the Brooke Kerns Athletic Training Room.
In the summer of 2003, a brand new floor was put in as well as new speakers and lights. In addition, the old bleachers were replaced and chair-back seating was added to the west side. The playing floor was dedicated Prochaska Court as part of the 2003 Homecoming Celebration in honor of Bill Prochaska's years of faithful service to Upper Iowa University and the athletics program. The Jim Day Suite was constructed following the winter sports season and was dedicated the following October on Homecoming 2004.
Dorman Gym opened in 1963 and was named in honor of John "Doc" Dorman and his wife Aurilla Cassidy Dorman, both Upper Iowa alums. Dorman was a 1900 graduate of Upper Iowa and a star athlete during, and due to the lack of eligibility rules, even before his collegiate years. His wife graduated in 1901.
Doc earned his DDS from Georgetown University. A slick-fielding shortstop, Doc turned down a contract offer from the Detroit Tigers before returning to Fayette to open a dental practice. For more than half a century, Doc practiced dentistry in the morning then took his place coaching on campus. While in Fayette, Doc’s name would become legendary in athletics, especially in college football.
