About Us

Community, Customer Focused Banking Since 1970

First Security Bank of Helena is a family owned and managed bank serving the Helena community since 1970. Our founder, Paul Caruso, Sr. was born and raised in Laurel, Montana and moved to Helena to open a bank, shortly thereafter starting First Security Bank of Helena. Paul has always believed that the key to creating a bank that was a true support for the community was to have a staff that personally addressed the unique needs of each customer and was familiar with their account, loan or business. He made sure that he was available for any customer to speak with personally.

Over 40 years later, Paul’s customer focused banking policies are continued by his son, Paul Caruso, Jr. and his granddaughter Amy Caruso Quarles who now head up daily operations as First Security Bank of Helena President and CEO, and CFO, respectively. When banking with us you can expect to speak to someone who is familiar with your account, your loan, or your business. Our dedicated and experienced staff will take the time to walk through your deposit, savings, or loan options and make sure you choose the option that best meets the needs of your family or your business.

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 the Carroll College, the Queen City Ballet Foundation and Komen Montana, The Kay McKenna Youth Foundation, and St. Peter’s Hospital Foundation.
