- MSMiguel SanchezMay 9, 20265.0This is my local office and everyone is very helpful.
- JMJames MaceyMay 1, 20261.0Slow and inefficient staff.
- SSStacyApr 16, 20261.0Every time I come in here, they are rude! No matter the day or time. This one guy (has braces on his knees) been there for years and always been nasty and acts like he doesn't want to work. I don't get how there's so many bad reviews throught the years and I'm sure ppl have called and complained and still nothing changes!!!!! So I guess if you have a nasty attitude you can work for the Mamaroneck post office!
- JMJulia MApr 14, 20265.0Please hire more workers like Cindy! She was fast and efficient. There were 5 customers ahead of me and she served them ALL in less than 5 minutes. Packages that she scans are already in the system and don’t take 24 hours like many other workers! Edit: Fernando took the time out of the remaining minutes of opening hours to help me pack and ship Jadon Doc martens while having a good sense of humor! Thank you Fernando!
- JSJoe SotallaroMar 13, 20261.0Made a passport appointment. Had it confirmed and everything. Went in, on time for my appointment. Not only was the staff member extremely rude, she informed us that all passport appointments were cancelled and that someone should have called us which they never did. When asked what we should do she gave a smirk & shrugged. If I could give this location zero stars I would
