Community Bank was founded by a group of individuals in Muscatine in 1980. These individuals saw a need for an alternative banking organization founded on exceptional customer service.  In 1983, an association was formed with Peoples National Bank in Columbus Junction. Several years later, the two banks merged under the Community Bank name.

Ownership of the Bank is part of a holding company organization:  C-B-G, Inc., which also owned the Wilton Savings Bank.  At the close of business on December 31, 2005, Wilton Savings Bank was merged into Community Bank. 

The main office of Community Bank is located at 615 Cedar Street in Muscatine, Iowa; the Columbus Junction Office is located at 229 Main Street, Columbus Junction, Iowa; the Park Avenue Office is located at 2506 Park Avenue, Muscatine, Iowa; and the Wilton office is located at 210 West 4th Street, Wilton, Iowa.
