About Community, Customer Focused Banking since 1970
Founding Principles

In 1970, Paul Caruso, Sr. moved to this community and established the First Security Bank of Helena as a family owned and managed bank. He believed that the key to creating a bank that truly supported its community was to have staff who personally addressed the unique needs of each customer.  Not only did staff know customers, accounts, loans and businesses, Paul made sure that he was also available for any customer to speak with personally.  

In 40 years, many things have changed, but President and CEO Loren Brown keeps the focus of First Security Bank true to its customers and their personal banking experience.  Old relationships are valued, new customers are nurtured, and improved or new products are offered.  Customers have access to larger loans and longer maturity terms.  We also offer enhanced deposit products including health savings accounts and instant issue debit cards. You’ll see more ATM machines around town. If you don’t want to leave home or if you love to travel, a mobile banking app and on-line bill pay make banking possible with just a click of a button.

In addition, the Bank continues to support local community causes such as Helena Food Share, YWCA, Big Bothers Big Sisters, West Mont, HBIA, Helena Exchange Club, 4-H, Leadership Montana, and Carroll College to name a few.  At First Security Bank, we continue to call you by name and Loren is still available for a personal visit.  Our experience and dedication make First Security Bank your bank of choice in our community.   

Community Involvement

Since its founding First Security Bank of Helena has supported the greater Helena community for more than 40 years. Our belief is that a strong local bank needs the support of a strong community, just as a strong community needs the support of a strong local bank. We contribute to numerous local and state causes, including Carroll College, the Queen City Ballet Foundation and Komen Montana, the Kay McKenna Youth Foundation, and St. Peter’s Hospital Foundation.
