Founded in 2016, Stealth Lacrosse is a co-op of Hermantown High School and Proctor High School.  It was created to provide JV and Varsity level student athletes the opportunity to play lacrosse on the Minnesota High School League level for both boys and girls.  The host school is Hermantown and originally most games were played in Hermantown.  With the introduction of a turf field in Proctor before the 2018 season, most games are now scheduled on Egerdahl Field in Proctor.

While Stealth Lacrosse is recognized by both the Hermantown and Proctor Athletic Departments, the program does not receive any school funding.  All expenses are funded through fundraising, sponsors and players fees.  

The Hermantown Summerfest 5K has unfortunately been cancelled for 2021 as has the entire Hermantown Summerfest.
