    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.

    I came here to drop off multiple items. Lucky for me, I was helped by Michael who assisted me with my transaction. This employee was beyond helpful, courteous, and patient with me. Michael was proficient at his job and even caught an error on an address, which saved me from a huge headache down the road. As I waited for Michael to do his thing, I couldn't help but notice they had three additional Postal Employees assisting other customers. All of the workers were professional and very efficient. Thank you Michael!

    See all

    I have been a regular customer of this UPS Store in La Verne and have used this location many…read moretimes, which makes today's experience especially disappointing. I came in to return two Amazon items and learned that these particular returns required printed labels. I was told the store could print them for a fee, and when I asked about the cost, I was told it would be $3.50 or I could simply print them at home and come back. I said that was fine and that I would do that. The issue came when I was then told that one of my returns could not be shipped back in the clear bag it arrived in and would need different packaging. I pointed out that the item had actually been shipped to me in that exact bag and showed the original shipping label still attached to it. Instead of simply explaining the policy professionally, the employee shrugged, rolled her eyes, and responded with an attitude. When I called out the unnecessary attitude, a gentleman came over and asked if he could help. I asked if he was the manager, and he told me he was the owner. I explained that there was clearly a need for customer-service training. At that point, the employee actually responded, in front of the owner, "You gave me attitude first." That response pretty much summed up the entire problem. Customers may misunderstand a policy, question a charge, or ask why packaging that was acceptable for delivery isn't acceptable for a return. An employee can explain those things politely. Rolling your eyes, becoming defensive, and arguing with a customer is entirely different. What was most disappointing was that this happened in front of the owner and there was no meaningful attempt to correct the situation or de-escalate it. Businesses spend a great deal of time and money earning customers and building loyalty. It can take one interaction like this to lose one. After regularly choosing this location, I will not be returning. There are simply too many other places to do business where basic courtesy and professionalism are still considered important.
