Whether you’ve been with us since the beginning or are just now joining us, First Security Bank is glad to have you along for the ride. We are building on 50 years of financial knowledge, long-held relationships with a solid and continued investment in our community, and we’re only getting stronger. Yes, we’ve built something special here. And we couldn’t have done it without you.
This is where we live.
Western Montana has changed quite a bit in the last half century, and yet so much has stayed the same. The entrepreneurial spirit this place embodies and the hard work and dedication of its people have allowed us the opportunity to jumpstart small businesses that keep the community alive. A growing population has given us the good fortune to see families find homes where their dreams can thrive. Our team gives back to the organizations and institutions that give this place the character and soul we all hold so dear.
It’s who we are.
First Security Bank was founded in 1972 as a local, homegrown bank for the people of western Montana. We are the friendly faces at the teller window. We are the lenders that listen to your stories and work to make your big plans into true accomplishments. We have seen your business flourish and your family grow. We are First Security Bank and we’re here for life.
Get started.
With a bank built on solid ground, we continue to be inspired by what you are doing. Where do you see yourself in the next decade or five? Whatever your vision may be, know that First Security Bank will be here to help you see it through.
