Bill Zwaan served as head coach of West Chester University for 20 seasons. Over the past two decades, Zwaan has put together one of the most impressive coaching resumes in all of Division II history. He is 162-76 in that span. He has won six Pennsylvania State Athletic Conference Eastern Division titles (2004, 2007,2008, 2015, 2017 and 2018) and in 2018 added an outright PSAC Championship crown to his list of accomplishments.

Additionally, he has been named Coach of the Year five times and guided the Golden Rams to NCAA playoffs, a school-record of 10 times. He has steered the institution to the national semifinal twice (2004 and 2013). His 21 years of service to Golden Rams football is the second-longest stint as the head coach of Ram football in school history.

Overall, Zwaan is 216-90, including his six seasons at Division III Widener University. He still owns the highest winning percentage in school history at Widener and led that institution to the Division III national semifinals.

In the fall of 2021, Zwaan surpassed two coaching milestones for victories when he earned his 200th career win at home against Edinboro in the third game of the season and then became West Chester University’s all-time winningest head coach when he topped College Football Hall of Famer, W. Glenn Killinger, with his 148th win at the school against Bloomsburg on Homecoming Weekend.
