After two rebuilding seasons, Plunket has led the Mules to a 26-13 (.667) record over the last three years.

In 2018, Plunket led the Mules to a record campaign. The Mules won their first eight games and finished with an 11-7 record, breaking the school record for wins in a season. They also set school records for goals and assists in a season and earned the right to host the ECAC Tournament, advancing to the final with a 19-5 defeat of SUNY Canton - their first postseason win ever.

Muhlenberg received votes in the Division III national poll three times in 2018. Among individual school records set were most goals, assists and points in a season, most faceoff wins in a career, season and game and most ground balls in a career and season.

The Mules continued their upward trajectory in 2019, going 10-6 and finishing with three Centennial Conference wins, their most in nine years. They again received votes in the national poll. One of Plunket's recruits became the program's all-time scoring leader in just his second season, and another was named CC rookie of the year and earned All-America honorable mention.

The 2020 team was off to a 5-0 start, outscoring opponents by more than a two-to-one margin, before the season was curtailed by Covid-19.

Plunket led Albright to a 57-17 record in its first four seasons of existence. With a squad comprised almost entirely of freshmen, the Lions went 16-3 in 2012, their inaugural season, advancing to the Commonwealth Conference championship game. Plunket was named Commonwealth coach of the year.

Albright finished 15-4 and 13-6 the next two years, earning votes in the national poll and winning the ECAC Mid-Atlantic championship both seasons. This past spring, the Lions were 13-4 against a schedule that featured four nationally ranked opponents and qualified for the Commonwealth playoffs for the fourth straight year.

In nine years at the Division III level, including five as an assistant, Plunket coached teams to an outstanding combined record of 129-42 (.754) prior to coming to Muhlenberg.

A native of upstate New York, Plunket earned his bachelor’s degree from Syracuse University in 2006. He was a four-year player for the Orange, helping the team to two Division I national titles and serving as team captain in 2005.

Plunket went on to play professionally for the Rochester Rattlers in 2007 and 2008, winning the MLL championship in 2008.
