The two very nice Lady’s today Aug. 27th 2025 went above and beyond to help me with a shipping problem. In the end we could not solve the issue on this end. But they were very helpful.

The average rating of the reviews on this Post Office does not do it justice. These women that work in there work their tails off and are extremely efficient at the their jobs! They need a raise if anything since both these women are doing the work of 3 people! Keep up the good work! Love your services! Thank you!

I love the staff here. They are always helpful and get me the best price. I do a lot of mail business, both using shipping easy as well as in person, and have never had a bad experience with the GV PO.
