I’ve had consistently excellent experiences at the Alamo, TX Post Office. From the moment you walk in, you’re greeted with a clean, organized space and courteous staff who genuinely care about helping customers.
Whether I’m shipping packages, picking up mail, or asking questions about postage and delivery, the employees here are always patient, knowledgeable, and efficient. They take the time to make sure everything is done right and that you leave with all your questions answered.
One thing I really appreciate is how smoothly the lines move—even during busy times. The team handles everything professionally, and I’ve never felt rushed or ignored. They’re especially helpful with explaining different shipping options and making sure you get the best value.
Special shout-out to Greg who went above and beyond to help me with a complicated international package—courteous, calm, and super helpful.
If you live in or near Alamo, you’re lucky to have a post office like this one. It's a model of how postal service should be: fast, friendly, and reliable.
Highly recommend!

I’ve always been helped here by this young guy. Greg I think is his name, he doesn’t have a badge or anything. He is very professional and knows what is the best option for me every time I send something.
