- AMAlisha MuelaJul 22, 20265.0I swear this post office has the most friendly workers, they're so nice and helpful.
- CKCassie KJul 20, 20262.0this place is so slow!!!
- DKDavid KeyteJul 7, 20262.0Staff is friendly and courteous enough. I printed out a label for package and put the package in the bin, because the line was long and it moves slow. It was never scanned and disappeared. I have no proof if I actually mailed it so insurance doesn't work either. Now I have to wait and have them scan every package I ship.
- RIRaymond Michelson IIIJun 22, 20261.0Unacceptable to have one person working and a line out the door the last few times I have been here….
