Millersville

A veteran coach with experience at every level of NCAA football, Ralph Clark has made his return to Millersville as the team's defensive coordinator--a position he previously held in 2014-15. 

Clark returned to Millersville as the cornerbacks coach in 2024, and was on the staff from 2013-15 before becoming the defensive coordinator at Seton Hill and then the first head coach for a start-up Alvernia program in 2017. Clark led Alvernia for five years and also served as the offensive coordinator and quarterbacks coach at Albright College. 

In his first stint at Millersville, Clark made significant improvements to Marauders' defenses as its coordinator, helping it rank fifth in the PSAC in total defense and second in passing defense during the 2015 season. It was a dramatic leap as Millersville had ranked no better than 11th in total defense in the eight prior seasons. 

Clark boasts a long career of coaching at both the collegiate and high school levels and working with a variety of position groups. Clark was the assistant head football coach and defensive coordinator at Bishop O’Connell High School in Virginia. He coached linebackers and served as the strength and conditioning coordinator at Virginia Union in 2011. In 2010, Clark coordinated the defense at Saint Francis University. That unit ranked among the NEC leaders in red zone defense, and linebacker Scott Lewis became the school’s all-time leading tackler.

Clark served as linebackers coach, pro scout liaison, travel coordinator, compliance coordinator and academic counselor over two seasons at Northeastern University. From 2006-2008, Clark coordinated the Rose-Hulman Institute defense to a No. 2 ranking in run defense in the Heartland Collegiate Athletic Conference (HCAC). His team also finished second in rushing defense in 2006, holding opponents to just 91.3 rushing yards a game.

Clarks’ collegiate coaching career began at Georgetown University as the secondary coach in 2004 and linebackers coach in 2005. Georgetown ranked No. 4 nationally in passing defense in 2004. Prior to joining the Georgetown staff, Clark coached at three high schools in the Virginia/District of Columbia area from 1998-2004.

Clark earned a bachelor’s degree in communications management from Robert Morris in 1998. He was a four-year letterman for the Colonials. He totaled 1,362 yards and 12 touchdowns as a running back.
