Montgomery led Denver to back-to-back trips to the Frozen Four (2016, 2017) and helped the Pioneers capture the 2017 National Championship. Additionally, he guided Denver to five consecutive NCAA Tournament appearances as the team reached the NCAA Tournament every season he was at the helm. Montgomery posted a 70-35-15-9 mark within the National Collegiate Hockey Conference (NCHC) over those five seasons to make the Pioneers the winningest program in the five-year history of the conference. During his tenure at Denver, the team also earned two NCHC Tournament Championships in 2014 and 2018, as well as being crowned NCHC Regular Season Champions during the 2013-14 regular-season. A two-time finalist for the Herb Brooks Award as NCHC Coach of the Year (2016, 2017), Montgomery won the Spencer Penrose Award as national coach of the year in 2017.
Prior to his time at the University of Denver, the native of Montreal, Que. spent three seasons as head coach and General Manager of the Dubuque Fighting Saints of the United States Hockey League (USHL) from 2010-13. In his three seasons, Montgomery accrued a 118-45-21 record, while leading Dubuque to two Clark Cup championships in 2011 and 2013 as well as an Anderson Cup as the USHL's regular season champions for the 2012-13 season. Montgomery was twice named USHL General Manager of the Year with Dubuque in 2010-11 and 2012-13.
He also spent four seasons as an assistant coach at Rensselear Polytechnic Institute of the NCAA's ECAC from 2006-10. Montgomery began his coaching career at Notre Dame of the then-Central Collegiate Hockey Association, serving as an assistant coach for the 2005-06 campaign.
A former center, Montgomery played in 122 career NHL games with St. Louis, Montreal, Philadelphia, San Jose and Dallas, recording 34 points (9-25=34) and 80 penalty minutes. He also registered 493 points (165-328=493) and 538 penalty minutes in 451 career American Hockey League contests with Hershey, Philadelphia, Kentucky and Utah. Before starting his professional career, Montgomery played four seasons at the University of Maine of Hockey East from 1989-93. During his time at Maine, he helped the Black Bears win two Hockey East Tournament championships (1992, 1993) and the 1993 National Championship, marking the first national championship in school history. During his senior season at Maine in 1993, he served as the team's captain and was selected as a Hobey Baker Memorial Award finalist, along with being named the NCAA Tournament Championship MVP. He finished his collegiate career ranked first in program history with 198 assists and 301 points (103-198=301), both of which still stand today. Montgomery was induced into the University of Maine Athletics Hall of Fame in 1998 and once again in 2017 as a member of the 1993 National Championship Team. His number #19 that he wore as a player at Maine is one of three numbers to be retired by the men's hockey program.
