Amherst men’s lacrosse head coach Jon Thompson is entering his 10th season at the helm of the Mammoths' program in 2020.

Taking over the reins in 2011, Thompson turned the Mammoths into a perennial national powerhouse - compiling a 125-47 overall record, a .727 win percentage, while leading Amherst to seven NCAA Championship tournament appearances and to several stints as the top-ranked team in the country. The 2018 NESCAC Coach of the Year and 2015 NESCAC Co-Coach of the Year, Thompson has mentored 31 All-Conference selections, including three NESCAC Player of the Years, and 26 All-Americans since 2015 in addition to the 2019 USILA Lt. Col. JI Turnbull Outstanding Attackman of the Year, 2019 USILA Iroquois National Outstanding Player of the Year, and 2019 USILA Short Stick Midfielder of the Year.

Returning to the NCAA Championships for the sixth straight year in 2019, Thompson led Amherst to its first-ever appearance in the National Title game, with the program previously being thwarted in three Quarterfinal tilts. On the road to the Finals the Mammoths avenged all three of their previous 2019 losses - downing Tufts in the Quarterfinals and archrival Williams in the Final Four while also playing past Elizabethtown (Second Round) and Wesleyan (Third Round) on their journey to Philadelphia. The Mammoths finished the record breaking season with an 18-4 overall record as the 2019 Division III National Runner-Up, a number that matched a program best for single season wins (18, 2015),

In 2015 Amherst concluded a historical campaign that included a program single-season record 18 wins (18-3 overall), which was highlighted by a 9-1 mark in NESCAC play, the program’s first-ever number one seed in the conference tournament, and a berth in the quarterfinal round of the NCAA Division III Championship en route to finishing the season with a national ranking of sixth. During the season, which included an eight-game winning streak accentuated by an emphatic 12-6 win over national powerhouse Tufts University, the Purple & White had eight players named All-NESCAC and All-NEILA, four players named ECAC Division III All-Stars, and six players selected as USILA All-Americans.  

Prior to the memorable 2015 season, Thompson enjoyed his second 15-win season in 2014 (15-5 overall), directing the Mammoths to a second round appearance in the NCAA postseason.

In the remarkable 2011 campaign, Thompson's squad reeled off 13 consecutive victories, including wins over Middlebury and Wesleyan, the program's first since 1989 and 1999, respectively.

The squad climbed to ninth in the USILA Coaches Poll and despite suffering a setback to Bowdoin in the quarterfinal round of the NESCAC Championship, Amherst secured its first-ever berth to the NCAA Tournament. After a 12-8 win over Keene State in its opening round game, the Purple & White downed Middlebury once again, 12-9, to advance to the national quarterfinals. Amherst's impressive postseason run came to an end with a 15-10 loss to RIT, but not before the team had posted a program-record 15 wins, finishing with a top-ten national ranking as four players earned All-NESCAC and All-NEILA honors.

Prior to Amherst, Thompson served as the head coach at NESCAC rival Colby College, where he led the Mules to the two most successful campaigns in the previous nine years. During his tenure in Waterville, Thompson guided the Mules to three wins over opponents ranked nationally in the top 10, including a win over the highest ranked opponent in program history (No. 5 Endicott).

While leading Colby to back-to-back postseason appearances, Thompson helped develop a trio of All-NESCAC selections, a pair of All-Americans, and Colby’s first two-time All-American. Equally impressive, Thompson helped the Mules raise the team’s cumulative grade-point average nearly half a letter grade in just four academic semesters.

During his time at Colby, Thompson and his teams helped organize and implement four separate civic engagement fundraisers, during which more than $45,000 was raised for the Pulmonary Fibrosis Foundation and Alpha 1/25, a Company in the 1st Battalion of the 25th Marine Regiment fighting in Afghanistan.

A native of Freeport, Maine, Thompson is a 2003 graduate of Brown University where he still ranks among the men’s lacrosse program’s top 10 in all-time goal scoring. Thompson, a former captain for the Bears, was a three-time All-New England selection while at Brown. He also earned both Ivy League All-Conference and All-Academic honors in 2002 and 2003, before capping his career as a USILA Honorable Mention All-American and a USILA Academic All-American in 2003.

Following a year volunteering as a member of the Brown coaching staff while playing professionally for the Boston Cannons of Major League Lacrosse, Thompson helped lead nearby Springfield to a Pilgrim League Championship as the Pride’s offensive coordinator in 2005.

Thompson returned to the Brown campus prior to the 2006 season, serving as the recruiting coordinator and second assistant for the Bears. After rising to the first assistant position and offensive coordinator for 2007, Thompson helped lead the Bears to one of the largest turnarounds in Division I. In Thompson’s three seasons coaching at Brown, the Bears transformed from a 2-11 team to an 11-3 team that won the 2008 Ivy League Championship with a victory over Princeton.

Thompson graduated Brown with a degree in sports psychology and now holds a Masters in Sports Psychology and is currently pursuing his PhD in sports and exercise psychology at Springfield. He and his wife Susanna have two daughters, Aida and Carolina.
