Giving Back to Byron, MN

Beginning in 2016, First Security Bank began awarding the Byron School District "Impact Fund." This annual donation of $15,000 is used within the Byron School District to (1) avoid programs being cut or to (2) cover the cost for necessary items that would impact Byron students for years to come.
