- HGHoney GoldenNov 26, 20255.0My girls at the post office are wonderful! They always take time out to make sure my mail gets taken care of quickly. Just an amazing group of people. 🥰
- ACAmanda CurcioJun 11, 20241.0If you have all the time in the world to spare, this is your post office. Zero urgency. There's a line but the workers just take whoever so you'll definitely get passed up if you're in line. Unfortunately this is the closest post office, but it's worth going elsewhere if you have anything else to get done today.
- CCCory CovertMar 14, 20231.0horrible service.
- DBDanny BadillaJun 6, 20175.0Place was empty and went right in and picked up my package, the two employees there were super nice and had no issues. From reading the other reviews I was expecting the worse but it seems they have revamped this place or nobody goes here anymore either way I was in and out and done.
