Pinnacle Bank

About Us

The communities we’re a part of make us who we are. From the hot springs of Thermopolis to the edge of the Black Hills in Newcastle, we’re proud to be here for the ranches, farms, businesses and families of Wyoming

Our Wyoming roots go back to the early 1900s with banks throughout agricultural communities. In 1972, our Wyoming branches became a part of a larger family of local banks started by the Dinsdale family. Brothers Tom and George Dinsdale, along with some friends, opened their first community bank in Palmer, Nebraska in 1938. They ran their bank much like they ran their ranches and farms, which helped them earn people’s trust. So it didn’t take long before they were ready to reach out to other towns and states, including Wyoming.

While a lot has changed in the banking industry over the years, our genuine approach and always doing what is right for our communities and customers has remained the same.
