Pinnacle Bank

Here we still believe in personal banking relationships. Over the last century we’ve grown from a small, rural, community bank into a strong and modern regional organization with over $6.25 billion in assets. But unlike many banks today, we still regard old-fashioned, neighborly customs—like greeting you by name and being involved in community events—as meaningful and important. We treat our customers like neighbors, and they reward us with great loyalty.

This makes us a little different, but we think it’s good business. We hope you agree.

Our roots in Wyoming go back to community banks that opened in the early 1900s. These banks primarily served agricultural communities and, over the years, they merged with others. Then in the 1930s in Palmer, Nebraska, another family of banks was started by a local cattle rancher and farmer named George Dinsdale. These banks served Nebraska’s rural communities, eventually becoming Pinnacle Bancorp.

Starting in 1972, several Wyoming banks began merging with Pinnacle Bancorp in order to increase their resources and better serve their growing communities. By 2000, banks in Torrington, Cheyenne, Cody, Thermopolis, Newcastle, Moorcroft, Worland and Mitchell, Nebraska, had joined the Pinnacle family. In 2007, a loan-production office was opened in Gillette.

Today, this merging of community banks into one strong organization gives you a unique opportunity to enjoy large-bank resources along with small-bank, family-run values. Sid Dinsdale, the founder’s grandson, serves as president of Pinnacle Bancorp, which serves commercial, consumer and agricultural interests in over 115 locations across Nebraska, Wyoming, Texas, Colorado, Missouri, New Mexico, Iowa and Kansas. Staying true to our values, each local bank acts with significant autonomy to best serve its customers and community.

With our local roots and neighborly style of banking, we’re proud to say we do banking “The Pinnacle Way.”

We hope you enjoy the difference a family-run bank can make in your life and community.
