More Resources. Same Local Decision-Making.

MidWestOne is now a division of Nicolet National Bank. This partnership combines resources and people to serve our customers and communities. We believe the best way to meet local needs is through local resources. Working together, we can help make the communities we serve stronger.   

No action is required from customers at this time. MidWestOne Bank will operate separately under one ownership until later this year, when operations transition to Nicolet National Bank. 

As we draw closer to the operational merger of Nicolet National Bank and MidWestOne Bank,  you will receive letters from Nicolet National Bank about your products and services, and what will happen next when we become one bank.
