    Worst post office. The lady at the post office said they have a new postal carrier that doesn’t know the town and when she gets lost she just marks mail as undeliverable. Then put my mail in the wrong pile and sent it back to the disruption center. I asked for the post master on duty and the lady in the office said she didn’t know what a post master was. Now the office won’t answer. Be careful folks, the group of people working at this location are either purposely not working and not doing their job or they are grossly uneducated and under-trained.

    Veronica was so kind and welcoming! She helped us at the Office with my daughter’s passport, and the whole experience was amazing. Thank you for your great service and warm smile!

    This is the absolute worst USPS branch. Trying to run a business and ship through USPS with this branch as your only option is impossible and has forced us to move all shipments to UPS.

    If i could select zero stars i would, ive been trying to get ahold of anyone there , they wrongfully picked up a package for ups containing medication, everyone there has zero clue whats going on, the very few people i could get ahold of kept sending me in circles. Everyone there is rude and unprofessional and could care less that their mistake is physically hurting someone missing their medication . I was told there’s nothing they could do?? Make sense.
