Our Mission
The mission of TrailWest Bank is to build loyal, long-term relationships based on trust, prosperity, and community.
Our Philosophy
TrailWest Bank is an FDIC insured, locally-owned, independent bank serving Western Montana. For decades, we have provided the people and businesses of the Ravalli, Missoula, Mineral, and Flathead Counties with a wide range of secure and dependable financial services—all with a commitment to personal service.
Over the years, we have experienced considerable growth, and continue to remain fiscally strong; meeting the ever-changing needs of the communities we serve. Today we live in an environment where many believe that bigger is better. Banks and other businesses are consolidating to streamline and achieve economies of scale. By streamlining, big banks are losing the personal touch that we feel is so important. We look at it as an opportunity to promote our relationship banking and a small town approach.
TrailWest Bank has set high customer service standards. We recognize that our relationship with our banking customers is the most important element to keeping them highly satisfied. By promoting relationship banking, we differentiate our banking services from big banks by creating a high value added experience for our customers.

Our Leadership













Our History
Founded in 1982 by Alan Bradley, Bitterroot Valley Bank began serving the Lolo area with a focus on personal service, a core value that is in practice to this day. By 2011, the bank had grown to six branches under the umbrella of Family of Banks, including locations in Missoula, Frenchtown, Bonner, Superior and St. Regis.
In 2012, Bitterroot Valley Bank merged with Ravalli County Bank, the oldest chartered bank in the state, founded by Copper King, Marcus Daly in 1895. The bank had been in the Shonkwiler family since 1967, first by Lincoln and then his son, Chuck, who is a bank Senior Advisor . The banks in Ravalli County have served the Bitterroot Valley for 120 years.
In 2015, West One Bank and their two offices in Kalispell joined the Family of Banks, allowing the bank to service customers in the Flathead Valley. Following this merger, the Bank began making plans for more branches in the city of Missoula. As part of those plans, we decided to rebrand to present a unified front across all of our locations. After months of deliberation, TrailWest Bank emerged.
TrailWest Bank’s iconic steer head logo has its roots in the longhorn cattle ranch, owned by Bill and Ramona Holt of Lolo, Montana, who were original investors in the bank. The longhorn is the quintessential symbol of the West — an animal known for its toughness and ability to survive adverse conditions, qualities that have embodied the bank throughout the generations.
