The 2025 season was Brad Schlemmer's 14^th as head coach and 17^th overall with Waubonsee's program, having served as assistant coach for three years prior to taking over from Waubonsee Hall of Fame coach Leslie (Ferguson) Raney. He is the program’s all-time winningest coach with 157 career coaching victories, and has been on the Chiefs’ sideline for 205 victories overall. Over the last 17 years at Waubonsee Schlemmer has been part of five Region 4 titles, three NJCAA District D titles, seven Illinois Skyway Collegiate Conference (ISCC) crowns, four appearances at the NJCAA National Tournament, and seven Region Runner-up finishes. As a matter of fact, Waubonsee has reached the Region 4 title game 12 of the 17 seasons he’s been with the program. Schlemmer has been tabbed the ISCC Women's Soccer Coach of the Year six times overall. 

Schlemmer’s 2014 squad grabbed the ISCC title and Region 4 Division I Championship to earn a berth in the National Tournament. Subsequently, he was tabbed the ISCC and Region 4 Women’s Soccer Coach of the Year. Due to the Covid pandemic in 2020 the Chiefs played an abbreviated 2021 Spring season, but it didn’t limit their success. Led by First Team All-American Olivia McPherson, Schlemmer’s crew captured the ISCC and Region titles to earn a berth in the NJCAA’s first Division II National Tournament, finishing ninth nationally. Waubonsee followed that up in the Fall by going 17-2-1 overall en route to winning the ISCC title and Region 4 crown once again. Consequently, Schlemmer was chosen the ISCC and Region Coach of the Year both seasons. Ranked as high as third nationally, the Chiefs knocked off defending National Champion Phoenix (AZ) College in their final pool play match at the 12-team National Tournament, just missing out of the final four due to the point differential. The last six season’s Schlemmer has guided the Chiefs to five ISCC titles, posting an 26-2-2 mark in league play over that span. During his time with the Chiefs' program nine players have attained NJCAA All-American status, 45 have been named All-Region, 64 have been tabbed All-ISCC First Team and 11 have been chosen the ISCC Player or Keeper of the Year. Under Schlemmer's leadership over 45 players have gone on to compete at 4-year colleges after Waubonsee. 

Schlemmer played three years on the varsity at Glen Oak High School in Canton, Ohio. He was a co-captain his senior year and named the Golden Eagles’ Offensive Player of the Year and earned the school’s Outstanding Senior Award. During his prep career Schlemmer gained a wealth of additional soccer experience competing with the Akron Canton Premier, traveling to play in numerous out-of-state tournaments and overseas in Denmark. He went on to play three years at Walsh University, an NAIA affiliate in Ohio. Coach Schlemmer returned to his high school alma mater as the boys’ varsity assistant and served in the same capacity at Perry High School in Massillon, Ohio, the following year. He has earned the United Soccer Coaches’ Level 2 Goalkeeper Certification and a “D” Coaching License. Schlemmer brings over 35 years of soccer playing, teaching and coaching experience to the Chiefs’ sidelines. In addition, the last four years he has been an assistant coach for St. Charles North High School’s Girls’ Varsity squad, helping the North Stars to a state runner-up finish in the spring of 2024. Schlemmer and wife newly wed bride Lauren, reside in Aurora.
