    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

    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 know a post office is a strange thing to write a review for however I felt compelled to say…read moresomething about this location's customer service. A little back story I don't live in this city AT ALL and decided to make the drive in hopes I would get even the slightest degree of better service compared to the upland post. And that's saying ALOT because they are HORRIBLE. Like those people could hardly care less about your experience or existence, including its manger. So I took the drive and let me just say... I'll come back here EVERY TIME. There were only two people working the entire front they got through the line with haste and they were super friendly from what I observed. It was my turn and Anthony helped me. HE WAS SOOOOO SWEET, helpful, accommodating and didn't make me feel like I was bothering him with questions or lack of knowledge. He even mentioned how he was working overtime that day and he still has the biggest smile on his face and great customer service. This is what your neighborhood shops should be like! More people need to do better and be there for their community. Thank you a million Anthony you set the standard.

    IMPORTANT if you work or live nearby!…read more Our office is a few blocks away from this location, on Towne. Our postal carrier has been NO SHOW for three days straight, resulting in many prepaid packages that needed to be shipped ASAP. We waited on the third day to see if the carrier would actually come. Surprise surprise, they did not. So we pulled into this location at 4:45PM with a dolly full of prepaid boxes. The rude lady behind the counter promptly refused to accept them, saying that our zip code is 91767, which is technically Pomona. Therefore, we could only take our boxes to a Pomona USPS office. What a crock!!!!! UPS, FedEx, DHL, nobody has such a ridiculous problem. The employees are just too lazy to scan the boxes, and therefore refused to accept them even though they were pre-labeled. Don't come to this location. I'm seriously tempted to send in a complaint. You will be treated rudely and refused service.

    People generally go to post offices for the sole purpose of sending or picking up mail. That makes…read moresense. But it doesn't mean post offices have to be boring or soulless looking. Therefore, I appreciate the simple but attractive architecture of the Claremont Post office. They have historic photos posted inside which are fun. It's neat to learn about the history of the places we kind of take for granted. Still my favorite post office to go to for postal services. Always excellent service even when it's super crowded.
