First Security Bank loves to give back! Here are just a few of our contributions over the years:

Byron Impact Fund

Beginning in 2016, we began awarding the Byron School District "Impact Fund," an annual donation of $15,000 to use for implementation within the Byron School District. This donation helps to avoid programs being cut and to cover the cost for necessary items that would impact many students for years to come.

Holiday Giving Tree

Each year, during the December Holiday season, FSB sets up a tree in which local community members are given the chance to "adopt" a local family or individual and provide gifts or items they would otherwise not be able to receive.

First Security Bank Scholarship Program

We have helped students reach their goal of higher education by awarding over $200,000 in scholarships to more than 100 area students.

Ronald McDonald House of Rochester

Annually, FSB hosts a "collection drive" where we collect necessary items for the Ronald McDonald House in Rochester. We then serve a dinner to the families there.

Make-A-Wish of MN

We have sponsored and supported Make-A-Wish of MN children and their families. This organization grants wishes to MN children with life threatening illnesses.

BrrrFest Celebration

FSB hosts a party for BrrrFest Celebration in Byron where we provide snacks and complimentary face painting for the community.

"Operation Kindness" drop off location

FSB is a registered Operation Kindness drop off location. This is for people to drop off their leftover Halloween candy and we mail it to the troops serving overseas.

Purpose of the card

First Security Bank and the Byron School District have had an ongoing partnership for many years. In an effort to support innovative school initiatives that support student learning in a time of limited school resources, a framework for ongoing support has been created. For these reasons, in partnership with the Byron School District, First Security Bank created the Byron Bear Debit Card earmarking a portion of the proceeds earned from the use of this card back to our area youth. Every time the cards are used to make a point of sale purchase, First Security Bank donates a percentage of the interchange fee back to the Byron Public Schools. The cards provide funds for programs and supplies that may otherwise not be possible. We encourage you to use the card that gives back!

Donation Guidelines

Byron Bear Debit Card

The main focus of these funds is to impact the greatest number of students in the Byron Public School District as possible with monetary gifts that will benefit students for years to come. It is also our goal to award money for items that would not be funded through the normal course of business without a fundraising campaign. This one time contribution is not meant to be used towards reoccurring expenses from year to year. All funding requests should be linked to the Byron Public School Strategic Plan and focus on enhancing or improving student learning. Money raised through this interchange system will be available two times per year with funding applications due by March 31st and September 30th of each year.

Donation Selection

Donation Requests will be reviewed and selected by a committee made up of First Security Bank of Byron employees in conjunction with Byron Public School officials in April and October of each year. Checks will be issued by May and November.

Donation Report Summary

A brief report summarizing outcomes and impact of the donated funds would be appreciated shortly after the ending date of the project. Project pictures are encouraged, and we request they be submitted with your summary report.

Application Submission

Applications may be submitted in person at our Byron MN location.
