COACHING BACKGROUND
Bill Harmsen began leading the Dordt Defender women’s program in 2018-19 after serving several years at Western Christian High School (Iowa). In 2025 he began working with Athletic Advancement & Development along with his coaching responsibilities.
His 2018-19 Dordt team proved to be record-breaking and historic as it posted a 20-12 season record with a 13-9 mark in the Great Plains Athletic Conference which was good for fourth place. The team earned an at-large berth to the NAIA Division II National Basketball Championship where its season ended in the first round of the 32-team field. The bid was the first ever for the Defenders and capped a season where they spent most of the year in the top-20 of the rankings and started the year with a 15-4 record.
Harmsen coached the team to a program best 80.3 points per game and topped the nation in defensive rebounds (31.96) and was 9th in scoring average.
The 2019-20 team followed up with another record-setting performance by posting a 24-8 overall record and a 15-7 GPAC mark. The Defenders spent the entire season ranked in the top-12 of the national poll. The Defenders also advanced to the semifinals of the GPAC post-season tournament for the first time in program history. Dordt qualified for the NAIA Division II National Championship field but didn't get a chance to play as the event was canceled due to the COVID-19 pandemic.
The 2019-20 team matched the previous year's points per game average with an 80.3 average and the team out-rebounded teams 42.8-33.1 with that margin ranking 7th in the NAIA. The team also converted 46.1 percent of its field goals which was 6th.
In 2020-21 the Defenders posted a 15-11 record and a 14-8 GPAC record, marking the third season in a row Dordt posted a winning record with Harmsen coaching. The team dealt with injuries early on in the season before going on a run from December 5-January 9 when it won nine out of ten games.
Dordt’s 2021-22 season featured a 15-game winning streak from December 18-February 12 and the team posted a 16-6 GPAC record that was good for a runner-up finish. For the third time in four years the team qualified for the NAIA National Championship field and advanced to the finals of the event before claiming runner-up honors. The team featured two All-GPAC first-team honorees and Ashtyn Veerbeek was named the GPAC Player of the Year—the first time a Dordt women’s basketball player has earned the honor.
The 2022-23 team won the school's first-ever women's basketball GPAC regular season championship and the team was 20-2 in GPAC play and 30-4 overall after starting the year 16-0. The Defenders were awarded a NAIA National Championship Opening Round Host Site berth and won two games in the field before falling in the Round of 16. They had two All-GPAC first-team performers in Karly Gustafson and Beiley Beckman and Harmsen was named Co-Coach of the Year by the GPAC for the second time in his career.
The 2023-24 team won its first 12 games before a setback to South Dakota State on December 12. The Defenders then won 14 games and ended the season with the regular season GPAC championship. Dordt then won three games to claim the GPAC postseason tournament and hosted the NAIA National Championship First and Second Rounds for the second straight season. Dordt proceeded win its four games in Sioux City to claim the program’s first ever National Championship. Harmsen was named GPAC Coach of the Year for the third time and the NAIA National Coach of the Year for the first time. The Defenders had four CSC Academic All-District performers, two first-team all-GPAC members and Macy Sievers was a first-team All-American and Karly Gustafson was a third-team pick.
Harmsen has coached nine first-team All-GPAC performers, two first-team NAIA All-Americans, three second-team NAIA All-Americans, two third-team NAIA All-Americans and four CoSIDA Academic All-American selections. The 2018-19, 2019-20, and 2020-21 teams had the best cumulative grade point averages for teams in their divisions with scores of 3.82, 3.82, and 3.83. The 2021-22 team posted a 3.77 gpa. Harmsen has a career 153-46 record and a career .769 college winning percentage.
Harmsen is also the co-director of Dordt’s Coaching for Transformation program launched in 2021 which is designed for Christian high schools who want to establish a mission for their athletic departments.

COACHING PHILOSOPHY
I feel coaching athletes is a way to get to know individuals on a personal level. To see student-athletes at their highest of highs and lowest of lows. This is where spiritual and emotional mentoring can take place. It is my goal every woman that is a part of the Dordt University women's program will be equipped with the spiritual, social, and emotional skills to prosper in the workplace as well as establish homes built on Jesus Christ.
