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.

Despite being farmers by trade, they opened what would become Pinnacle Bank in 1938. Over the next 80 years, the bank grew under the leadership of the Dinsdale family to serve communities across eight states.


Roy and Jack, George's sons, first started expanding their family-owned bank in 1959 when they purchased the bank in Neligh, Nebraska.

Throughout the 60s and 70s, Roy and Jack opened more banks in rural communities across Nebraska. In 1976, Pinnacle Bank entered the Kansas market.


The Dinsdales purchased First State Bank, which had a long history serving the community, and their locations in Keene, Joshua, Cleburne and Burleson. This was Pinnacle Bank’s first expansion into Texas.


Our banks in Texas unified under a single name, Pinnacle Bank, to reflect our connection with Pinnacle Bancorp, Inc.


Pinnacle Bank acquired First Bank and added 6 new locations throughout Johnson, Tarrant and Parker counties, for a total of 12 branches in Texas.


Pinnacle Bancorp purchased Woodhaven National Bank and its eight locations in the Fort Worth area.


Pinnacle Bank acquired Crockett National Bank in December 2022, adding an additional five branches and two loan production offices, our first in the state of Texas outside the Fort Worth area.

In 2020, Pinnacle Bank opened new branches in Granbury and Rio Vista. Our bank network now spans 8 states with 167 locations, including 29 in Texas. We continue to look for opportunities to grow, including opening and remodeling locations throughout our service area.

Today our bank network is still proudly owned and managed by the Dinsdale family. 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.
