Staff were chatting to each other about transferring to another job as I walked in. After a couple minutes, they looked at me as if I were a stranger walking into their living room.


This post office is the most disorganized group of staff and supervisors of any business I've ever seen. They are not consistent with anything they do. Olga who has pronounced she was master lies about anything and everything. They decided not to deliver to our house because there is a gate but after th gate is 7 more residences and its not private road there's a gate because of animals. We were told they couldn't deliver to our house anymore after doimg that service for years and years them blamed it on a private gated driveway. It's not a driveway ota a road with houses beyond it. I get notifications all the time saying customer requests package to be help at post office. We have never requested that. I requested my packages be delivered. Then they accidentally one day deliver a package and no one can tell me where it went. It's lost! Olga lies and tells you want you to hear. She offers to take your phone number and figure out a problem but never calls this has happened 5x at least with me. No one on that whole building knows what's goimg on. Today Olga said there was a new post master. I asked her for their contact information. And she refused to give me their name or any contact info and said have a good day and walked away. I'm pretty sure as a federal community business that information is mandatory to give if someone asks. Worst post office staff ever in this location. And I've been here almost 30 years.


How is a person supposed to get their mail if they can't receive mail at their physical address (which, by the way, is less than ONE block from the post office) when the post office is only open until 5pm?! I leave to early and get home too late, and the key code door feature has not worked since I've had a P.O. Box there for the last 3 years. Pretty frustrating when you are expecting time sensitive mail. Isn't it a crime to mess with someone's mail? How about not having access to your own mail?!


Abysmal service at this post office. I've lived around the area my whole life, and any interaction with this post office has ALWAYS been negative. Paychecks do not arrive on time, important dates like court summons arriving days later than the DEADLINE date. Trying to expect mail to come at a reasonable hour? Some nights you gotta wait till 8 PM to get your mail from the post office. And so with all of the negatives of the delivery, surely if you just go in, it's good right? WRONG. I went in to pick up a package addressed to my grandmother that had an 'arrival' scan but hadn't been loaded onto a truck in the morning for delivery so instead of waiting an entire day, she asked me to go get her package for her. After looking it up on the official USPS website, either on the back of a form or on a plain piece of paper with the words "[NAME] has the permission of {Addressee name} to pick up their mail." And then signed by the addressee, this being my grandmother. I also took my photo ID to show them as the website stated, and when I tried to pick up the package, the first lady said she couldn't do anything with a note and then referred me to the Post Master (Who should very much not be holding his position). Once I started speaking to the Post Master and explaining my grandmother has a bad hip and back and was laying at home and asked me to pick up her mail, I went over what I had read regarding pickups, and he sits there and nods and when I get to the end he goes real slow and points at the name "How do I know who that is?" Uhh, I don't know, you have their written permission, you have their handwriting on file, you have the package addressed to them, and you have MY ID. If I was in here trying to take something why would I be showing my ID to you? Regardless, he said "If you bring her in her we can help you." Not budging on anything. Alright. So I drove back home, woke my grandmother up, had to get her out of bed with her bad hip and back, and go to the Post Office again. This time, the Post Master didn't even interact after how rude he was, he avoided my Grandmother and me completely and let the first woman handle us. Except, they actually COULDNT DO ANYTHING since the package had only just arrived that morning and apparently they were 'still sorting through the mail'. What good is a post office when you can't even pick up your mail being held there? Why did they have me drag my grandmother out of bed when she's in pain and just wants to rest, only to tell me they actually CANT do anything? This place has a high turnover rate with any postal worker who isn't the Post Master. They have a 'crime prevention sheet' tacked to a board inside written on TYPEWRITER. Do not expect any kind of reputable service here.


I keep getting mail that does not belong to me or my address this person never lived here and I have been sending it back to the post office and it camels back to me!! Ughh so distracted I’m trying to have it dilivered to the right person but they send it back and I can’t even call the PO to notify them because they never pick up. It’s been 3 month of me trying to return this but at this point I’m sorry I’ll have to grow them away. It’s mail from EDD which is why I thought it was important to get to the right person but I’m done. Trying. PO employees: same number does not mean same address get that straight.


It's a post office. They do their job. The only complaint I have is that the USPS has not yet figured out a way to cross reference a physical address with a PO box for customers to whom they DO NOT DELIVER MAIL. So, every time a vendor sends something USPS and has only a physical address (because they don't accept PO boxes, or like Amazon won't allow you to put the PO box in the address), it gets returned. Even when you think something is coming UPS (which never has issue), they will sometimes hand off a package to USPS for final delivery. We can't win. The only way we can "intercept" our mail when this happens is to sign up for text tracking and get a notification for EVERY TOUCH POINT in the delivery chain. Then, when we get the notification that the package is being returned, we can call the post office and ask them to hold it. This only works if we can get to the PO the same day, otherwise things get returned. How is it that the USPS has the tech and the means to manage a text tracking system can't seem to create a mechanism that cross references a physical address to a PO box?!?!? We have to re-register for this PO box every year and show PROOF OF RESIDENCY AT OUR PHYSICAL ADDRESS!!! I will never not be infuriated by this challenge, but at least I discovered a way around it. This has never been suggested to me by staff, even though I've asked about how to handle it several times.


I always have a pleasant experience with staff. This post office is small but it gets the job done!


Will be calling tomorrow ,,, but this post should be public. We live way up the hill ... gate to our house is about 1/2 mile. one of your delivery persons buzzes our gate and we buzz him im and he delivers our packages. one of your delivery persons refuses to drive our driveway and while thy buzz the gate to tell us packages are here, they leave them. We will likely no longer accept "leaving them". The weather is turning and you need delivery agents who will bring them to the house and not leave them in the rain for hours. if your delivery person does not want to drive up the driveway to deliver the package, find a new one. Is that not your job?


This Post Office,{95446}, is the most useless waste of taxpayer monies I have seen in my life!! The staff is disgusting with arrogant disrespect and appear to thoroughly enjoy hanging around for the opportunity to tell local residents, trying to arrive before they close, that they are closed!! As the staff loiter around inside they stand ready to call guards at the first sign of the outrage they've managed to muster for their entertainment. They go by their own time, not what you see on your phone and they scurry to close the door and turn the key when you approach with cell phone in hand saying "It's 4:56, look!!" The worst part of all this is the smile they get while watching and waiting for your reaction!!!! No "small town charm" in this small N. Ca. tho though less than 1000 residents call this their full time home. Most people would naturally assume a community based, public commodity shared by just about all locals, as most do not have local mail delivery as an option, could and should be a warm friendly place? This post office does not even honer online tracking notices! You package is there when the staff says it is!, got a problem with that!? Its not a question, its what your told. Just remember people, hold your rage until you have walked away, don't let them see it because it is what they want to see!!!


The Postal Service receives NO tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations. You must get flustered easily when the environment is not centered around you. I've used this post office for well over twenty years and have never been treated any less than professionally. Did I get a warm blanket, a puppy to cuddle and a glass of warm milk? No I did not. Sounds to me that's what you were looking for and didn't get. It's a post office, not a esteem booster business. Imagine this concept, the world doesn't revolve around your pantywaist feelings. Go a pair and spine and get on with it.

Jim Doire, you sound like a person how has everything laid out all nice, neat and just the way you want it in your little happy place, a charming little town in a bubble, that's in a bubble protected from outside influences comfortably surrounded by other like minded twits and after 20 years in any one place I would expect that a developed comfort zone has taken shape. If you think or expect everyone in this zany leftist colony sees life through peachy rose colored glasses as you do then your nuts!. Thanks for your opinion on my opinion, its good to know a public forum is available, and being used for the sole purpose expressing our individual opinions. My thoughts have been heard and found engaging, Thanks,
