- JTJessica TietjenFeb 11, 20264.0I always have a problem at this location. As a business owner I would not go here. The clerks are always so nice but something always happens with my packages here.
- JWJon WDec 31, 20255.0The Mount Sinai location is the best USPS office in the area. I'm usually in & out far faster at this office than the other ones in my area.
- TTTiffanyOct 1, 20175.0The staff is really nice and friendly! They helped me out with my questions about taking boxes and other delivery stuff. They were also really quick when the morning rush of people came and helped us all out in an efficient manner.
- BBBob BlackNov 11, 20155.0I'm a daily customer and find the clerks to be super nice and very efficient . The Postmaster is very professional and courteous. My mail carrier is the best.
