“I like the Uptown post office but How is anyone supposed to mail anything when the hours keep getting changed by staff? They've always been nice, helpful, & knowledgeable. Does the Postmaster General know about this? The hours they were open was until 4:45pm and has been for decades. The people here like this. Today there was several others trying to mail things when I tried to mail things but once again, another sign was taped to the window with yet Another change of hours. Is someone trying to intentionally get the Uptown post office to close for good? Sure does seem like it. Please stop this & go back to regular hours. Thank you”
“It has never failed that I go humbly into our Post Office with an unusual problem and throw myself on the mercy of their counter. It can be James or any of the staff that reassure me they've got this, and they do. Cheerfully, without making me feel like the inadequate customer I feel I am! I have always loved the postal workers, I especially love my Millstadt ones! Thank you! Merry Christmas!Penny Jestes”

“I have no complaints about my experience here. There were two people in front of me and two behind me and we all got the same treatment and respect. My own ignorance to what I needed to do was my only holdup but I was given accurate assistance to get what I needed done. They for sure sell stamps and can mail things certified.”
“Really helpful staff. Also; good to support usps. Awesome mission serving all of USA.
Edit: yikes. Lots of Karen’s and Kevin’s in these reviews. Maybe don’t vote for people actively defunding the post office and they won’t be so stressed out to help y’all.”

“Had such a wonderful and friendly experience today while mailing out my dad's box. The clerk was so nice and handled the transaction with utter professionalism! Thanks for the hard work and kindness!”
“I went in to have a package delivered.
Only took a few minutes.
The clerk was great. I was given a few options. I chose what I wanted. I paid and left.”
“Clerk was very sweet! The kiosk was down when I went in. She did let me know they tried to fix it and ordered a new part for it. Wasn’t too long of a wait, but there was only one register open.”
