On Wednesday, February 18, I reached out needing two full sets of trial documents totaling more than 5,400 pages, with everything completed before the following Monday. After calling multiple large chain print shops and being told the turnaround wasn't possible, I contacted Copymat and spoke with Shawn, the owner. Shawn and his team immediately stepped in with professionalism, clear communication, and a genuine willingness to help. They completed the entire project by Friday morning, allowing me to finalize everything by Friday afternoon and stay fully on track for trial. The quality of the work was excellent, the turnaround was incredibly fast, and the customer service truly went above and beyond. It was a huge relief during a stressful week, and I'm extremely grateful for their help. Copymat Walnut Creek absolutely saved the day for our firm, and we will definitely continue using their services. Experiences like this are exactly why supporting local small businesses matters.

Where everyone else saw a problem, he saw a puzzle. He thinks outside the box to figure out how to get things inside the box. His creativity, persistence, and problem-solving are on another level. He refused to quit until he found a solution. In a world that keeps talking about AI replacing people, Mike is a reminder that true ingenuity, experience, and determination are still uniquely human. He's a one-of-a-kind packing and shipping genius, and if you have something difficult to ship, don't waste your time anywhere else.

It's in a little tiny strip mall and I think most people wouldn't go there. The only reason I went there is I was looking for FedEx and I guess it's an authorized FedEx place so it gave me the map to it, but I had never been there or had known about it the value that you get is incredible and just that kind of old-fashioned nice service. I loved it glad I went.

Unfortunately my three month experience here was consistently disappointing and I will not be renewing my PO Box. When I asked for a key to my own PO Box the owner told me "most clients don't need a key, they just ask me for their mail." That alone should have been a red flag. Package drop offs sometimes take several days to show as scanned by the carrier -- not ideal if you're time sensitive. The worst experience was a missing package. Staff told me it was delivered on a Sunday when they're closed. I checked -- it was actually delivered on a Wednesday morning when they were open. After being told to file a claim with the sender I received a text the next day saying my package was there. When I picked it up the owner seemed confused and simply handed it over -- no acknowledgment, no apology, zero accountability. I genuinely wanted this to work. It didn't. Their prices are low for the POBox but not worth the headache. I'll be taking my business elsewhere.

This review is almost a half year overdue! But Lynda was amazing as a notary and getting apostille…read morefrom the State! My in-laws, from outside the country, were visiting in September 2025. During their visit, a matter came up requiring an apostille, or they would simply have to cut their trip short and return home to handle. I reached out to Lynda through Yelp and got an immediate response. We coordinated an appointment and she met us at my home and took care of business. So why does she deserve 5 stars for essentially doing the same thing any other notary public willing to go to Sacramento would do? The exceptional customer service! We ran out of legal paper and she was willing to bring some she had at her office for no charge. Saved me a trip to the store, and she didn't nickel and dime and insist that we pay her for printing, etc. Additionally, after our initial appointment, we realized something had to be corrected and we needed an additional copy. She came back to the house late that evening, AFTER her other job, to get it squared away so she could go to Sacramento for the apostille the next morning. No additional charge! Lynda provided thorough communication throughout, including the next day as she went to Sacramento. She asked if she could deliver the documents to our house the following day as she also had work that night, and unfortunately that didn't work for my in-laws schedule, so she made time to swing by that afternoon before starting her other job that evening. It's not cheap to get an apostille done, but the cost was more than reasonable and Lynda's service was worth every penny! Thanks again Lynda!

Why do you even offer to be a FedEx authorized service center if you can't even bother honoring the agreement with the company you are supposed to represent?

Very disappointed in the level of service, lack of quality, and no value what so ever in what they offer.
