This post office on Mill Road has the nicest people working there. It’s always a good experience to go there.


I recently had a gift sent to Westhampton, NY which took several days to scan from the originating post office. I filed an inquiry and within a very short period of time the Postmaster at the Westhampton post office contacted me. She was so professional and kind and assured me she would be on top of it, which she was. I received text notification that the package was delivered however the recipient said they had not received it. I contacted the Postmaster whose name is Maura, and she immediately went over to the recipients home to check the mailbox. In fact it was there. The recipient never checked their mailbox. In my opinion, this Postmaster went above and beyond and couldn’t have been nicer. I know the Post Office has recently been given some negative publicity but this Postmaster’s response truly reflects what the USPS is! Kudos to Maura, Postmaster Westhampton PO!


Wow, that was so nice of you to take the time to write such a great review this postmaster. I am impressed with how amazing she was and thankful that there are nice people like you to recognize and them!
