Commercial Bank was founded in Whitewater, Wisconsin as a State Chartered Bank in 1913. We are a locally owned, Independent Community Bank. Today, we have Banking office locations in Whitewater and Janesville, Wisconsin.

At Commercial Bank you are not just an account number. It is our goal to provide personalized, quality service to every customer we serve. We believe this Banking web site is one more way to provide safe, secure and convenient services to you!


The Commercial Bank West Towne Branch and its interior ATM located at 1260 W. Main St., Whitewater, WI will be closing in December. The final date to transact business at that location will be December 15, 2015.

The closing of this Branch is necessary due to the pending sale of Danielís Sentry Food Store to a private developer. After December 15, 2015 all future banking can be transacted at the Main Office, 200 S. Fremont Street, Whitewater, WI 53190 and the Janesville Branch located at 1400 Black Bridge Road, Janesville, WI 53545.

The Commercial Bank is the owner of its Branch Bank space at West Towne and therefore it is our intent to reopen the Branch and its ATM as soon as it is feasible to do so. We apologize for the inconvenience created by the necessary closing of this Branch.

Please call us with any future questions:

  • Commercial Bank Main Office (262) 473-1111
  • Commercial Bank Janesville Office (608) 756-1111

Once again, thank you in advance for moving through this inconvenience. Check the Commercial Bank website for Main Office extended hours sometime in the near future.
