At First Interstate Bank, giving back is part of who we are.
On Wednesday, September 16, First Interstate Bank will close all branch offices at noon local time for our ninth annual Volunteer Day, a companywide initiative that encourages employees to serve their communities.
Almost 400 service projects are planned across the Bank’s 10-state footprint, ranging from food bank support and park cleanups to nonprofit outreach and school supply drives. Volunteer Day reflects First Interstate’s long-standing commitment to community service, a core value since our founding nearly 60 years ago.
“Volunteer Day is one of the many ways we invest in the communities that support us every day,” said Jim Reuter, President and CEO of First Interstate BancSystem, Inc. “By stepping outside the workplace and into our neighborhoods, our employees build meaningful connections and help make a difference where it matters most.”
While branch offices will be closed the afternoon of September 16, the Client Contact Center will remain open until 7 p.m. MT. Clients can also access their accounts via ATMs, online banking, and the mobile banking app.
Regular banking hours will resume on Thursday, September 17.
