    I run a very small business from home, and this post office has been the best part about moving from Denver to Southampton. I'm in most days, dropping off already-labeled packages, and the employees are always friendly, and really know their stuff. They are incredibly efficient, and my customers are always raving about how quickly they receive their items. Plus, on the very few occasions that I have had a package get lost somewhere down the line, they go out of their way to help me research the problem. I wouldn't be able to run my business the way I do without them! Can't even express how grateful I am, *especially* during the holiday season when they are slammed! Plus, our mail carrier Lance is fantastic. I've lived in a lot of places, multiple different states, and he is hands down the *best*. Between Informed Delivery and Lance, I never have to worry about something not arriving as it should. I dread the day that he retires!

    The staff moved like they were training for the USPS Olympics-gold medal in efficiency. I held the door for an older lady and she said “I’ll tip you later.” Iconic behavior on her behalf. The parking lot is a bit tricky, but to be fair driving isn’t my strong suit. Overall, a great visit, would absolutely do it again.
