Questions and Answers

Why the merger?

The merger with First Midwest Bank has allowed Great Lakes Bank to partner with a high quality, financially strong and customer focused organization. First Midwest’s unwavering commitment to relationship banking and customer service is similar to that at Great Lakes Bank. We believe the merger has allowed us to better serve your growing banking needs through a broader array of commercial, retail and wealth management products and services offered by First Midwest.

Now that the merger is complete, you have access to First Midwest’s over 100 full service banking centers plus debit card access to over 50,000 surcharge-free ATMs worldwide in the AllpointTM network.
