- DJDennis JohnsonDec 20, 20255.0They are always helpful when I am mailing packages to family for holidays and birthdays
- SSScott StillitanoNov 30, 20251.0On 10/19/2025 I mailed 3 money orders which added up to 2,300 dollars. These money orders were for first month's rent and security deposit. My new landlord said he received the payment on 11/30/2025. That is 42 days. Never trust the USPS with deliveries of any big payments. I was horrified, not knowing where that money was. It made me feel so powerless.
- RRRebecca ReymanJan 14, 20215.0In 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.
- EQEeraj QaisarNov 23, 20185.0This is the best little post office, efficient and nice staff. No crowd, convenient hours. Much better than the larger one in Hamilton. I hope this location is kept intact.
- RRrichMar 20, 20165.0Personable, Friendly and always Helpful - a real pleasure
