    I wish I could give them a 10 out of 5! Absolutely the BEST usps office I’ve been to. It is tiny but it has everything you need. The staff is super helpful and patient. If you want to mail the passport renewal application, you HAVE TO choose this USPS office. They know a LOT about this and will give you tons of help. BEST experience with the mailing office EVER.

    In the pandemic world of virtual everything, I had to mail out 40 packages with invitations & favors for a virtual baby shower. I searched the area to see if there were any USPS with better reviews than mine, because I knew I would need some patience & kindness when I walked in with two bags full of boxes. I decided to drive 25 minutes out of my way to this office, and it was more than worth the trip! She was kind, efficient and patient with me - first time I’ve left the post office in months and felt confident that my packages will get out safely! I had to call a friend on the way home just to talk about how happy I was to enjoy a trip to the post office. Incredible service, I would recommend this location to anyone who is anxious about USPS experience.

    Great little hidden jewel, without the big volume of people
