A friendly team behind the counters, quick personalized service and an overall neat look of the building (with optimal parking options) all go towards the 5-star rating that this place deserves.

I wish there’s an option for negative stars. Extremely bad service and bad attitude.

Some USPS employees are extremely rude and unprofessional when dealing with customers. Their attitude can be very disrespectful and condescending.

I have now not received my package twice. Both were labeled correctly, no reason to not be delivered I don’t know why this mail lady who delivers all the packages on Rose Ave can’t seem to make her deliveries correctly. This is my second package within two weeks that was not delivered to my house and returned to post office for pickup.
