On September 11, 2019, all First Interstate Bank locations closed for the afternoon so our employees could volunteer in our communities for our second annual Commitment to Community Volunteer Day. This collaborative and powerful impact was felt across our footprint.

We look forward to our next Volunteer Day on September 9, 2020.

If you have any questions, please contact your local First Interstate Bank branch, or call the First Interstate Foundation at 406-255-5393 or
