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.
From 1981 through 1999, the Dinsdales would acquire seven additional locations across the state. These two decades would see Pinnacle Bank expand significantly in Wyoming.
Growth across Wyoming continued during the 2000s, including entering two new markets.
