Welcome to the Upper Midwest Lacrosse Officials Association
The Upper Midwest Lacrosse Officials Association (UMLOA) is the only organization for men's and boys lacrosse officials in the state of Minnesota.
We service high school and youth lacrosse in the state of Minnesota as well as college lacrosse games across the upper midwest (including Minnesota, Wisconsin, North Dakota, South Dakota, and Iowa).
Game changes/cancellations now come through ArbiterSports, not the assigner. Check your email for Arbiter Connected details.
