First Interstate Bank Polson

First Interstate traces back to 1968, when Homer Scott Sr. bought a small bank in Sheridan, Wyoming, and grew it into what’s now the largest bank headquartered in Montana, still run out of Billings. The Polson branch on Highway 93 covers checking and savings, home loans, personal and commercial lending, and wealth management, plus an Orange Checking account with no minimum balance and no charge if you bank online and go paperless. Stop in for a face-to-face conversation about a loan or a new account, use the drive-thru on a busy day, or call ahead at (406) 883-8800 to check on weekday hours before you go.
