Sinclair took over the reins of the men’s hockey program in the spring of 2015. He came to Middlebury from Skidmore, where he served in the same role for 10 seasons. The former Panther All-American was Middlebury’s interim head coach in 2002–03, after serving three seasons as an assistant coach for long-time head coach Bill Beaney. Sinclair is just the fourth men’s hockey coach at Middlebury since 1946.
Sinclair spent 10 seasons behind the bench at Skidmore. In his second season with the Thoroughbreds, his team finished third in the ECAC East/NESCAC interlock and hosted a first-round postseason tournament game. Sinclair led the team to the ECAC semifinals three times and was named the league’s Coach of the Year in 2006–07. He was also a finalist for the Edward Jeremiah Award as the National Coach of the Year.
While at Skidmore, Sinclair obtained his Master of Arts degree in 2011. As part of his master’s work, Sinclair published a piece in The International Journal of Sports and Society titled “Building a Collegiate Athletic Leadership Model for NCAA Teams,” which he wrote with Tim Harper and Jeff Segrave in 2014.
As a player at Middlebury, the senior defenseman was a first-team All-American and ECAC selection in 1993. He began his coaching career at Middlebury Union High School, leading the team to the 1996 State Championship.
He returned to his alma mater as an assistant coach from 1999–2002, serving as the team’s interim head coach in 2002–03 while Beaney was on sabbatical. That season, Sinclair guided the team to a 22-5-2 record with a trip to the NCAA final four. The Panthers also finished first in the NESCAC and advanced to the league’s championship game. Following the season, he was again named a finalist for the Edward Jeremiah Award.
The following season, Sinclair moved to Williams College, where he served as head coach of the women’s hockey program for two seasons prior to arriving at Skidmore.
