Bill Zwaan Sr. and his son Bill Zwaan Jr. have built a football legacy that stretches across two generations, beginning with their early days at West Chester University where they captured multiple PSAC Eastern Division championships and earned an NCAA Division II playoff berth.
During his playing career, Bill Zwaan Jr. earned first‑team All‑PSAC honors in 2007 and was crowned the Maxwell Football Club Tri‑State College Player of the Year, a testament to the talent he honed under his father's guidance.
A shared journey
After two decades at West Chester, where he became the program's all‑time winningest coach, Bill Zwaan Sr. retired, paving the way for his son to take the helm at Delaware Valley University, where he now serves as head coach while his father assumes the role of tight ends coach.
The duo introduced a modern no‑huddle offense, a scheme Zwaan Sr. learned from his son, which has already begun to reshape the team's dynamics and set the stage for a promising season.
Their family extends onto the field as well; Bill Zwaan Jr.'s children, Jack and Billy, regularly cheer from the sidelines, continuing the Zwaan tradition of community involvement and on‑field passion.
The Aggies open their campaign on September 4 at Ursinus College, marking the next chapter in a story that blends coaching expertise, familial bonds, and a shared love of the game.
