    I always have a great experience at this branch, but Daniel really went above and beyond. He helped me with my account and took the time to walk me through everything until the issue was fully resolved. He was patient, professional, and genuinely cared about helping. Couldn’t recommend Daniel and this branch enough!

    I have nothing but great things to say about the staff at the Flossmoor. They take care of me and know me by name, and that is a great feeling to have as a customer of this bank.
