“I’ve utilized this post office for 4 1/2 years prior to moving and today I’ve had the best customer service experience. Mr. Hemphill assisted me with retrieving a package that had the wrong address on the shipping label. I spoke to him last week and after he got my information, I told him I will be in contact. By the time I called him the package was already in route to be delivered to the wrong address. He was able to contact the carrier and have the package held back at the facility for me to pick up.

Couldn’t have been more grateful. Thank you Mr.Hemphill !”

“We worked with Twyla at a passport appointment and she got it done so quickly and easily! At the other location, they kicked us out because we didn’t have enough time to fill out our application and complete the appointment. Today, Twyla helped us get our passport so efficiently and we love it. Definitely will return to this location for another. :)”

“Postal clerk greeted & acknowledged everyone who walked in. Wait was short, and from my observation there seems to be a good rapport between the usual customers and clerk.”

“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.”

“Despite some of the comments, this USPS location has been pretty good to me. Every time I've gone, the people working there are helpful and get things done. Never had a problem with a package or anything. Just a heads-up, though: it gets packed during lunch and right after work, so try to swing by at a weird time if you can.”

“After reading the reviews I was bracing myself for a bad delivery experience but I did tell myself I would leave a decent review if I didn't have any problems. The only issue I had was that they are slow to answer the door when you go knocking to check in. Other than that, I was in and out in about an hour and done before my appointment time.”
