    The 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.

    The regular mailman finds my mailbox, but the filling guys have no clue what they're doing yesterday, I did get mail, but they left the mailbox open. So I don't know if it blew down the street. It was breezy also I went to buy stamps 1 day. There were 2 people ahead of me, and it probably took a 1/2 an hour, very poor customer service. They're getting the why shouldn't their government workers

    The 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.

    I'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.
