- MAMarc AnthonyApr 7, 20265.0Love this Post Office and all the staff ! I leave my town to come here
- SSSamDec 16, 20251.0Tell me why this guy driving the post truck on 12/16/25 just pulled out in the middle of oncoming traffic almost causing an accident? And not watching for cars coming? I almost just got hit
- KMKellie MorrisJul 20, 20241.0I requested my mail be held from July 2nd to August 1. I returned home today to find that, not only was it not held, the postal person SHOVED everything into a tiny apartment mailbox! He ripped my mail, wrinkled the mail, and shoved packages in. I will not stop until this person is written up or disciplined. He repeatedly shoves packages into my mailbox that should be placed into a parcel mailbox.. Expect my visit on Monday morning.
- ECErika CruzApr 10, 20245.0best experience very nice people always helpful
- KZKimberly ZurlaFeb 17, 20215.0Patricia couldn’t have been nicer or more helpful. I can only image how hard it is dealing with nasty people all day who come to the post office without a pen or tape or necessary tools to accomplish their task. And then take it out on the lady’s who have to suffer through dealing with them!
