Ritter is now in his 12th season in the Michael “Mickey” Heinecken Coaching Chair position as head coach of the Middlebury College football program. Ritter has earned a 50-38 mark in his first 11 seasons with the Panthers, including a 13–3 mark during the 2006 and 2007 seasons. Following the 2007 NESCAC Championship season, Ritter was named both the NESCAC Coach of the Year, as well as the Region I AFCA Coach of the Year.

In his time as the head coach for the Panthers, Ritter has coached 72 All-NESCAC selections, while seeing his players break 32 school records, with 37 NESCAC players of the week awards. Seventy-seven players have earned All-NESCAC Academic honors during his tenure, as 12 more were tabbed as Academic All-Region picks, with one National Scholar-Athlete selection. Additionally, one former Panther plays in the NFL.

Since 2009, the Panther offense led the nation in seven categories, while sitting in the top 10 nationally in a dozen more. The 2011 squad was the most prolific,  leading all of NCAA Division III football in four categories, including: passing yards per game (345.71), plays per game (82.25), as signal-caller Mac Foote led the nation in completions per game (32.43), while averaging a nation-best 342.43 passing yards per game.

The Holden, Massachusetts, native began his coaching career immediately following his graduation from Middlebury in 1982. That fall he joined the coaching staff and spent six years as the defensive coordinator under Heinecken. Following his six years at Middlebury, Ritter took the head men’s lacrosse and assistant football coaching position at Tufts University, where he worked as both the offensive and defensive coordinator during his tenure.

Ritter returned to Middlebury in the fall of 1996 to take on duties as an assistant football and assistant men’s lacrosse coach. He was named the head coach of the football program in December of 2000.

Ritter continues to work as an assistant coach in the spring for the three-time NCAA Championship men’s lacrosse team.

He and his wife, the former Sue Parsons (’83), reside in Middlebury with their two daughters, Katie a sophomore basketball and lacrosse player for Middlebury and Chrissy a first-year Middlebury field hockey and lacrosse athlete and their son, Bobby.
