I live on Dunbar and have also been to the office....I love my mail carriers. They are awesome! I have always had the office workers that have gone out of their way to answer stupid questions for me and also help me pack boxes for shipment also. Thank you for doing your job well...along with all the extra work you have to do delivering all the packages that used to be ups and guys need raises!


This Post Office is absolutely ridiculous!! They won't deliver important packages because they don't want to walk to the front door or they leave my packages in the ditch or in the freaking mud instead of on the porch!! Horrible!!


This post office is full of some of the most rude employees I've ever met. They seem to make excuses so that they don't need to help you. Previously we unknowingly showed up a couple minutes before they opened. When we got there the door was locked. We were mocked and laughed at instead of politely being told they couldn't open for another minute. They mis inform you so that they do not personally have to deal with your requests and problems. I can assure you that you will receive nothing but attitude if you request any help other than them tearing you off some stamps.
