Greg Cronin

Cronin began his career as an assistant coach at his alma mater, Colby College in 1987–88 and then became a graduate assistant at the University of Maine from 1988 to 1990, then as an assistant for Colorado College from 1990 to 1993. He returned to Maine to be an assistant coach from 1993 to 1995 and was named interim head coach following a scandal that banished head coach Shawn Walsh from the bench for one year in 1995–96, leading the Black Bears to the Hockey East championship game in 1996 where they lost to Providence College, 3–2. Cronin spent time working with USA Hockey before joining the New York Islanders in 1998. He served as an assistant coach with the Islanders for 5 seasons before being named head coach of their minor league affiliate, the Bridgeport Sound Tigers. He coached the Sound Tigers for 2 seasons with great success, going 78–61–16–5. On June 16, 2014, Greg Cronin was named assistant coach of the New York Islanders.

On June 16, 2014, Cronin was named an assistant coach to the New York Islanders, after serving three years as an assistant to the Toronto Maple Leafs.

On February 18, 2011, Northeastern announced Cronin would be suspended indefinitely due to possible recruitment violations. The suspension lasted six games, with Cronin being reinstated prior to Northeastern's quarterfinal playoff series with Boston University. Northeastern would win that series, capturing two of three games at Agganis Arena and make it to the Hockey East semifinals for the second time in three years, where they fell to Boston College.

The Huskies opened the 2008–09 season expected to contend for home ice advantage in Hockey East (4th place or better) for the first time since 1997–98. The Huskies went 23–9–4 in the regular season, leading the conference until the final day when they lost at Boston College 4–1, falling to second place in Hockey East in the process. Season highlights included Northeastern's first sweep of Maine in 25 years, a win over Boston College in the Beanpot for the first time since 1994, and winning 2 of 3 games against both of the previous season's Hockey East Finalists, Vermont and Boston College. The Huskies opened the postseason by defeating the University of Massachusetts Amherst in the Hockey East Quarterfinals at Matthews Arena, 2 games to 1, with the 3rd game being won in overtime on a goal by freshman Alex Tuckerman.

In 2005 Cronin replaced Bruce Crowder as head coach of the Northeastern Huskies men's hockey team. Cronin inherited a team that graduated almost all of their key players from a 15–18–5 team and had little hope of competing in the short term. The team went 3–24–7 in 2005–06 before posting a 13–18–5 record the following year behind the development of many of Cronin's recruits. The team further improved to 16–18–3 in 2007–08, winning their first playoff game in years in the 2–1 series loss to the University of Vermont.

† Cronin served as the head coach for Maine during the year-long suspension of Shawn Walsh starting on December 23, 1995
