ISB Community Bank was established in 1918 in Ixonia, Wisconsin; since then the bank has grown to offer services at six locations throughout Waukesha and Jefferson Counties. Recently, the Milwaukee Lubar family made a long term investment and commitment to enhance the bank’s stability, profitability, and growth. This was a positive agreement for the bank’s customers, shareholders, employees, and the local communities.

At ISB, we strive to provide the highest quality financial services. For over 94 years, we have been an independent, community owned bank that offers a full array of financial services including personal checking, savings, loans, investment services, as well as a full suite of business banking products. ISB has a variety of value-added consumer and business products and services that help our customers achieve their financial needs. At this community bank, our decisions are made locally and we have outstanding customer service. 

We invite you to browse our website or visit any of our locations to learn more about ISB Community Bank.
