With over 93 years of experience under our belt, we think we've pretty much perfected the art of community banking at it best.

We've remained responsive to the needs of our communities, and have six convenient locations to serve you: Ixonia, Dousman, Hartland, Oconomowoc, Watertown-Church St, and Watertown-Oakridge Ct.

Online, on the phone, or in person...we're ready to assist you with whatever you need.

As of July 21, 2010, FDIC deposit insurance was permanently raised to $250,000 per depositer. For more details, please click here to view our video on new FDIC insurance limits or contact a Relationship Banker today.

All funds in a "noninterest-bearing transaction account" are insured in full by the Federal Deposit Insurance Corporation from December 31, 2010, through December 31, 2012. This temporary unlimited coverage is in addition to, and separate from, the coverage of at least $250,000 available to depositors under the FDIC’s general deposit insurance rules.

The term "noninterest-bearing transaction account" includes a traditional checking account or demand deposit account on which the insured depository institution pays no interest. It also includes Interest on Lawyers Trust Accounts ("IOLTAs"). It does not include other accounts, such as traditional checking or demand deposit accounts that may earn interest, NOW accounts, and money-market deposit accounts.
