    We've used OS bank for many years. The staff is always friendly and super helpful. Today I brought my 6yo to cash in her change and they made her experience amazing! They took their time with her and even letting her help with the counting machine! Thanks ladies!

    The bank tellers at both the window and drive-through are the best. They’re always very friendly and have a smile on their face. I have never had a bad experience since they opened as old second.
