Webpage Changing! 

Our webpage and online banking login page will be changing after 5:30pm on Friday, February 13, 2026 to reflect the acquisition with Farmers and Merchants Union Bank. When you visit the website after this date and time, you will see a new landing page with customer information regarding the changes, and your online banking links. Your current online banking log-ins will still continue to work on these new pages. There will be scheduled downtime from 10:00pm on February 14 until 10:00am on February 15. After that you may continue to use your online banking log-ins as you normally would. If you have any questions regarding this, please give us a call at 920.885.2700.

Thank you for your understanding!
