The ladies in the post office are awesome! They are very professional, do a great job and are always more than helpful. They have been understaffed for months but one would never know it. We are very lucky to have such a great post office in our little community!


This post office “sucks”! The clerks are unhelpful and rude! They lose packages on a regular basis. It’s obvious they don’t give a “sh~‘¥” about the people who no choice but to use this location. This situation needs to be addressed immediately! There is absolutely no need to be rude and ugly to people!


Within the last year there was a new girl hired who has made our lives hell whenever we have to mail ANYTHING. She's extremely rude and impossible to work with. She will do her best to make sure your experience is the worst. She has mailed packages back to senders with the excuse of the name didn't match the exact name on the P.O. Box. And yet our boxes get over loaded with junk mail that doesn't have our names on them. So how come one is OK and the other isn't. I've ended up holding on to boxes to mail in nearby towns just so I don't have to interact with this employee. And I've informed all friends and family to use Fed-ex or UPS whenever anything needs to be mailed.


We sent a package to this post office that was "Delivered" to a PO box. The box was put aside according to PO employees and never delivered. They were supposed to search the office for the package but we are yet to confirm delivery from our friend. This is very frustrating. The employee she spoke to just acted like it was tough luck the last time our friend inquired about her package.
