“I love going to this location. I have to go to the post office often for work. I've never had an issue here. The only problem I've ever seen was other customers with no compassion and patience.”

“The clerks are always helpful and friendly. They definitely don't get enough credit for the hard work they do here. They may not have all the amenities available at larger locations, but as a local post office it's well stocked. Expect to be in and out within 10 mins, there's usually a few folks in line. Have some patience and cut these folks some slack.”
