Our Roots and Banking History
Pinnacle Bank is known in the communities we serve for our strength, stability, service, and values. It's been that way since our beginning in Palmer, Nebraska.
During the Great Depression, Palmer's only bank closed. So, brothers George and Tom Dinsdale, along with some friends, decided to do something to help their community.
Roy and Jack, George's sons, first started expanding their family-owned bank in 1959 when they purchased the bank in Neligh, Nebraska.
Roy and Jack continued our bank’s legacy of expansion, purchasing banks across rural markets throughout neighboring states, including Wyoming.
The Dinsdale family purchased Fort Lupton State Bank and entered the Colorado market for the first time.
In 2000, the Dinsdales purchased Western State Bank in Gallup, New Mexico. This marked our entry into the New Mexico area.
Today our bank network is still proudly owned and managed by the Dinsdale family. We now have 161 locations, and we continue to look for new opportunities to expand. As we grow, one community at a time, we recognize that each has a unique culture and set of needs for us to adapt to. That’s why our decisions are made locally. Banking decisions, as well as how we support our communities beyond our branch walls, are decided by people who are a part of and have a vested interest in the community.
We’re proud to be part of Pinnacle Bancorp. While our bank may have grown out of our hometown – our core values have remained a mainstay at every location. We face the future with confidence knowing we have a firm foundation.
