- MMMarcosJun 26, 20261.0Worst bank in the country they charged me $23 to cash my check. It’s a 2.5% like nobody does that. I will never open an account with this bank.
- PDP Van DornOct 11, 20235.0Excellent service!
- RWRobert WebbSep 29, 20231.0Horrible service in here I was sent a new customer identification form from another FIB branch and they refused to notarize it in here. The guy was rude and it was ridiculous there was not a customer inside the building at the time as they were not even busy. Pathetic way to show the public how you operate, don't go here they treat you like dirt.
- DWDyland WilsonJul 2, 20185.0I hve banked here and boulder branch for 6 years. They have ALWAYS been the most professional and friendly bank I have ever had the pleasure of doing business with. I have no idea what the other people are talking about!
- SDSteven “Property Pruners” DetkowskiAug 26, 20171.0I am sitting here at the bank and ran out of gas with the manager telling me they don't cash checks at the window. Why?
