“A recent transplant to Sioux City, Dillon has been a part of our bank since he graduated from high school. Since that time, he’s focused on helping our customers get the loans they need to build their dream homes or expand their businesses.”


In the late 1980s, the bank became a part of the Pinnacle Bank family when it was purchased by Sid Dinsdale. More than just a banker, he sees himself as a friend, neighbor and link in the community. The kind of person who does business with a handshake.
