106 South Electric, West Yellowstone, MT 59758
We are your small town community bank that delivers big service!
Thank you for your interest in commercial financing and banking services in the West Yellowstone, MT and Island Park, ID areas.
Celebrating our Centennial anniversary in 2019, First Security Bank was the first bank established in the West Yellowstone area, founded on a growing need for community banking services in the southern end of Gallatin County. We have always taken pride in being a vital part of a growing year round community, as well as helping to meet the needs of thriving and expanding business services and related industries that have developed to serve our visitors, seasonal residents and year round community. We are fortunate to call this beautiful area, which includes the West entrance to Yellowstone National Park, our home.
