How do you say our name?

It's pronounced DEE-Trick. 

Now that we have that straight, what’s happening?

We’ve served the people of Illinois for over 100 years. Now, Dieterich Bank of Effingham, Illinois is purchasing First Bank’s branches located in Breese, Chester, Columbia, Red Bud, and Waterloo, Illinois. It’s ok if you’re having trouble with the pronunciation, you can visit the same branches that you have grown accustomed to visiting for an in-person lesson. 

What should I expect?

The conversion weekend is August 7-9, 2020 and we will keep you informed throughout the process. The primary goal for both banks is to make this transition as seamless and convenient as possible for our customers.
