I’ve had an extremely disappointing experience at this post office. The staff are rude, unhelpful, and unpleasant in every possible way. There’s a complete lack of professionalism and courtesy, simple questions are met with attitude, and it often feels like customers are treated as an inconvenience rather than being served with respect.
A little politeness and effort would go a long way, but unfortunately, that seems to be missing here. Definitely not a place I’d recommend unless there are no other options available.

Asked employee to grab my package and she said “I’m not gonna do it and I’m not finna do it” after there been refusing to deliver my package’s after just moving into my home. I’ve come into the usps location about 5 times now and they continue to refuse to deliver my packages to my front door and refuse to let me pick them up, telling me they’ll be delivered then returning the packages to the sender. Absolutely horrible I wish I could never get packages delivered through them.

Amber was absolutely amazing! She helped us with our passport applications quickly, professionally, and with such kindness. We had tried another USPS location where they couldn’t assist us, but Amber took care of everything perfectly. She truly deserves recognition!

Have no idea what they’re talking about, make up their own rules as they go. Been sending envelopes for years without issue. All of a sudden today my envelopes have to be sent as packages because of some made up garbage. Kiosk lets you send envelopes with a rigid designation. But to them, that doesn’t apply to my case. Wasted time waiting for a supervisor, but crap rolls down a hill, just as incompetent as the desk employees.
