I use them all the time for filings for different clients. They have always been really fast and professional.

I'm a Los Angeles business attorney. My client needed expedited LLC formation through the Secretary of State's office. Sierra Express did an excellent job at a very reasonable rate for two in-person visits. I'm completely satisfied and I'd use them again. read more

I Just incorporated a new business and asked for a VERY specific filing time and same day service, and another odd request. They were extremely courteous, gracious and went well above and beyond paying attention to every detail and keeping me updated through the whole process. Their fee was extremely fair and reasonable. We got out the door paying less than legal zoom charges while getting GREAT personal service including; knowing when our papers were filed, asking questions so that it was done exactly how and when we wanted it and they didn't even charge us until AFTER they filed (and payed for) our paperwork! Outstanding Experience, we will refer to them for any future similar needs! Thank you Guys & Gals! Danielle Etl CCHT read more

Excellent customer service and delivery! I worked with Alyssa on an expedited delivery to the Secretary of State's office. She was very polite and helpful, all documents were delivered on time, and we received communication from the company every step of the way which provided great peace of mind. Alyssa was great with explaining the steps of the process and quick to respond when an issue came up with our paperwork. We will definitely use their service again if we ever need it! read more

I've used Sierra Express on numerous occasions for my expedited filings with the SOS office. They've always delivered on-time as promised. Fees are reasonable compared to other courier services. Highly recommended. read more

This is great service company. Sierra Express is real reliable. I used use one personal service who do the filing in Secramento. Charged me $250 service fee on top of other filing fee. And took more than 4 weeks. I used this person for more than 15 times for my client's entity filing. But Sierra Express is the best and reliable. Strongly suggest. read more

Just used this service prior to a deposition in order to get Secretary of State documents for some corporations. When we didn't receive the documents from the Secretary of State after several weeks we contacted them to get a status. Well just days before the deposition we found out that they actually never even dropped off our request with the Secretary of State. This place is not reliable and has prevented us from using a key piece of evidence at out deposition. Afterward we called their office and talked to a person named Steve. He sounded like the owner or the manager. We thought maybe he'd be able to somehow remedy some of the damage that we had incurred because of his company. Instead of addressing our issue, he became very aggressive toward us and completely lied to us. He said that we never called to give them our credit card information despite the fact that the person he was talking to did exactly that over 3 weeks prior. Not only are they incompetent but they lied to us and basically called us liars and verbally attacked us. Then he hung up on us. I don't know if this is the way to run a business. We try to pay you money to do a service...You completely fail in performing that service...then you blame your customer and insult them and hang up without trying to figure out a way to address the problem. I understand that most of their customers are not in Sacramento and are far away but you have to at least try to serve your customers...no matter how far away they are. Nice way to treat your customers...no wonder they are horrible. Stay away at all costs unless you like to deal with incompetent people who do not even know to fulfill an order and then blame and attack you for their own incompetence. read more

This is the second time I've used their service to pickup and drop off equipment. They were on time each time and did a great job overall. I will use them again! read more

My company, Angelus Medical Clinics, in Southern California, used Sierra Express about 2 weeks ago to quickly file papers with the Secretary of State in Sacramento. Sierra Express was efficient and with a reasonable price for same day service. I highly recommend them. read more

I found myself needing to make a business filing with the Secretary of State in Sacramento that needed to be done in a hurry. I looked into it and found out there was a way to get it done very fast if I was willing to pay a substantial rush fee and if I filed the paperwork in person. In person??? I am in Los Angeles and it is a far drive or an expensive plane flight to go to Sacramento. Surely someone must offer a service to do this in Sacramento. A quick Google search later, I found Sierra Express and they took care of it for me for a very reasonable fee with excellent service. They were great about answering my questions to make sure I had all the right forms and they even called to confirm that my FedEx envelope had arrived successfully. They scanned and e-mailed my confirmed filing as soon as they had picked it up. I don't imagine ever needing to do another filing in such a hurry, but if I did, I wouldn't hesitate to use Sierra Express again. THANK YOU!! read more

This is a great courier service company. They are very friendly and helpful, not to mention extremely polite. I'm all the way in Southern​ California and used them to deal with the Secretary of State. They always follow up and provide documents and receipts. When I had a question I just called in and was helped by a very knowledgeable girl named Lisa. I would for sure use them again. read more

I have used Sierra Express Delivery several times to file documents with the Secretary of State. I had previously used another delivery service but they were slow to pick up the documents and return them to me and I never knew where we were in the process. With Sierra Express I can order my service online rather than overnighting to a courier so they are delivered the same day. Then they send me an invoice and confirmation that my articles have been delivered. I recently expedited a set of articles and they picked them up the same day they were available and scanned them to me. They have been so easy to work with and I will definitely be using them for all my courier needs in the Sacramento area! read more

Wow! I had an emergency situation today, googled couriers in the Sacramento area, and called Deanna at Sierra Express. I needed them to bring paperwork from Folsom to Truckee (2 hour drive), with just 15 minutes notice, and I needed it guaranteed! Deanna gave me a fast answer (yes), took all my info, followed through as promised on both the pickup, keeping me informed, and the delivery, and helped me solve my problem. All for what I thought was a very reasonable price! Thanks Sierra Express Delivery! read more

Incredible first class service! I worked with Steve on a package that had to be picked up in Rocklin and then delivered to the Greyhound bus station - all within an hour. To top it off, Steve had to pay $20 out of his pocket and trust that my payment to him would be there. He did the courier service in 45 minutes and had the package on the bus on time. Kudos to Steve and Sierra Express for on time, on target service. read more
