First Security Bank first opened its doors in downtown Missoula in 1972. Quickly growing to a family of seven full-service branch locations, we also established full-service locations in the nearby communities of Corvallis, Hamilton, Plains, Thompson Falls and, Stevensville.
First Security Bank offers a full-range of banking products and services providing individuals and businesses with the help necessary to achieve their financial goals, today and throughout their lives.
We operate our own management teams in the towns we know well, because we live here too! We value being an integral part of our many communities and are proud to serve friends, neighbors and local businesses not only with superior banking products and services, but with considerable investments of our own time and effort to help non-profit and community organizations wherever we are. In fact, we support more than 400 local community organizations every year.
In 1996 we joined the Glacier Family of Banks, owned by Kalispell, Montana-based Glacier Bancorp, Inc. (GBCI). Glacier Bank is a regional bank providing world-class financial services to individuals and businesses throughout the Western United States. This has enabled us to serve our local communities with the same unique personal attention and friendly service our customers have come to expect, with the added resources of our much larger banking family.
