Arrived to ship late.
Richard G.

This particular USPS has an amazing and friendly staff. They always go out of their way to help you no matter what. I stopped going to the Glendora one due to problems with staff. Also, Glendora shuts off access to drop-off packages inside and out around 6 or 7 pm. The greatest thing about this USPS is that you can come after hours and still ship your packages. I have gone here as late at 9:10 pm to drop off packages that were already boxed and had labels on them. Easy and fast. Thank you, USPS San Dimas, for all of your hard work!!!

A convenient location to mail letters with a large mailbox in the parking lot, you can drive up and drop in business-size envelopes. For larger packages, go into the lobby. They sell boxes and envelopes in a variety of sizes, and greeting cards. Very convenient to choose a card, sign it, and buy a stamp in one transaction. I actually chose my card, stepped to the side to address it and use the vending machine to buy stamps. They locked the doors and I could not go back to the lobby area to pay for the card. The lady said "we're closed," and didn't want to let me in. When I explained that I had not paid for the card, she unlocked the door. One cute fact that I observed is the side street on the East side of the building is named "PONY EXPRESS COURT," how clever is that???

This is probably one of the friendliest and cleanest post offices I've been to! This location also offers Drive Up Drop off option making things convenient to mail off prepaid postage letters and parcels. Inside is roomy with a long hallway and the interior looks up to date and not worn down.

Deante is the best person I've ever met at a post office, or frankly any service establishment I've ever been.

This post office is conveniently located near my workplace in La Verne so I have at times dropped…read moreoff letters in the drive through mailboxes, or stopped quickly inside to use the self checkout machine to weigh a package or envelope, pay for postage and send it through the drop slot. Today I needed to pay for a medium sized priority mail box to send clothes to the east coast that my daughter forgot at home when she came to visit for spring break. I figured $22.95 was worth it when it was heavy items like jeans, shorts, skirt, etc; plus it comes with a tracking number; plus it'll get there by this Thursday. In any case, while I was prepping the box and labeling it, I observed Xuan and the male staff working beside her patiently answer questions for several customers ahead of me in line. I would like to thank them both for being kind to the people, and to thank Xuan for helping me so efficiently. You might say they were just doing their jobs, but I say kindness while doing one's job is not necessarily a given these days. So thank you!

I have always had terrible experiences here but this last visit was my last straw. They are just SO…read morerude to you here it's ridiculous it's like every single worker just hates their life and their job !! Just drive to the San Dimas one they're so sweet and will actually help you ! Idk how Frank is still employed after so many reviews about him so that just goes to show what kind of business this is. They don't care about trying to help you and they won't do any extra steps for you. The Asian lady that works there refused to scan my package when it was a prepaid label but I went to the SD location and they took my package right away and even scanned the label to make sure I was good which the other lady refused to do ! Just don't go here go to San Dimas
