Bill started his athletic career at Westford Academy by joining the football team as a freshman in 1961. The following year, as a sophomore, he would see a lot of varsity action on Westford’s first undefeated state champion football team. A week after the fall season ended, Bill was called down to the AD’s office to meet with his football coach Chet Steele, who also happened to be the wrestling coach. Coach said that the wrestling team needed a 110 pounder and then proceeded to tell Bill, “Welcome to the team.”

In Bill’s very first match, he appeared to pin his opponent before a technicality erased the victory and ultimately, he suffered a defeat in that initial bout (to 2010 Hall of Famer Stephen Henry). However, that would be his only loss of the season; Bill went undefeated over the rest of the season, winning both the Sectional and State championships. In doing so, he not only became Westford’s first State champion but Bill also led the team of six individual champions to the 1963 State team title. Following the state meet, Westford was ruled ineligible to participate in the New England Tournament, which brought its season to an end.

As a junior, Bill was a two-way starter on Westford’s second undefeated, state champion football team. In the winter, he moved up two weight classes to 121 pounds, went undefeated in dual meets, and finished second in both the Sectional and State tournaments. As a senior, at 127 pounds, Bill went undefeated, capturing his second Sectional and State titles. Along with teammates Roger Hall (three-time State champ) and Lee Zwicker (State runner-up), the trio led Westford to a second place finish in the team standings. Shortly thereafter, during Bill’s only trip to the New Englands, he earned a third place medal. Hall and Zwicker earned New England titles at that same tournament and the combined efforts of the three medalists propelled Westford to a third place finish. Following in Bill’s footsteps, his three brothers (Wayne, Kevin, and Dana) competed in wrestling at Westford.

In 1967, Bill married his high school sweetheart, Christine, and they had three children: daughters Kimberly and Kerry, and son Billy. Bill began his coaching career in 1980, when he served as a volunteer coach with the Westford youth program. He stayed with that program for more than 30 years, coaching kids from 1st to 8th grade. When the Westford head coaching job opened up in 1983, Bill applied for and was offered the position; he then proceeded to serve in that role for the next 22 years. Two years into his term at Westford Academy, with the help of assistant coach Todd Lobo, the team won the 1985 Division 2 State Championship; in the process Bill was honored as Division 2 Coach of the Year. The 1993 Westford Academy team won the Division 2 North Sectional title, led by son Billy, who was a two-time Sectional champion; Coach Corr was named Sectional Coach of the Year in 1993.

Bill was inducted into Massachusetts Coaches Association Hall of Fame in 1998 and into the Westford Academy Hall of Fame in 2001. His 1985 state championship team was inducted into the Massachusetts Chapter of the National Hall of Fame in 2010. Bill joined the Massachusetts USA Wrestling coaching staff under Rick Freitas in 1984. In 1987, Bill and Jeff Goor took over the leadership of Massachusetts USA Wrestling and for next decade they would be involved in every aspect of the program. They led a cultural exchange team to Europe in 1989, where they wrestled teams from Germany, Belgium and Holland. In 1993, Bill was honored as Massachusetts USA Man of the Year.

Although Nashoba Valley Technical High School in Westford dropped their wrestling program in 1998, supporters worked closely with Principal Matt Ricard to get the sport reinstated in 2015. Bill took over the new program and was fortunate to coach his two grandsons, Kevin and Kenny Keins, with son Billy as his assistant coach. During the 2020 season, Coach Corr joined the 300 win club and, as the decade advances, he continues to forge ahead to further milestones.
