DeKalb County United was founded in 2017 by DeKalb area natives. The club was established in order to unite the communities of DeKalb County and surrounding areas through soccer. Though the club is relatively new to the area, its members, fans, and staff have been dedicated to making an impact both on the pitch, and in their local community. The club made an introduction to the local public when they held a jersey reveal party at a local bar and grille. In April 2017, the club was decided to be not-for-profit, and as such assembled a Board of Directors, which consisted of the team's founders John and Jenny Hall, Colby Newquist, Brian VanBuren and Steve Duran. 2018 SEASON DeKalb County United had a modest first season in the UPSL in 2018, finishing 5th in the Midwestern Central conference, with 12 points, and a record of 4-0-6, with wins coming in both games against Union Dubuque F.C. and Joliet United. 2019 SEASON DeKalb County United began play in the UPSL Midwest Central in April 2019, with matches against Cedar Rapids Inferno, Croatian Eagles SC, Milwaukee Bavarian SC, and Union Dubuque.
