US Continental has been a contract managed services client with Onsite Computing since 2013. We tried other IT companies in the past but Onsite was the only company that could do what they said they would do. They’ve recently setup the IT for our 2nd facility in Corona including our new VOIP phone system. They have also made us compliant new with PCI security standards that our bank required for credit card security. We highly recommend them to other businesses looking for a cutting-edge IT partner.

I’ve trusted Onsite Computing with both my business and personal IT needs for over 15 years, and their service has consistently exceeded my expectations. On more than one occasion, when I feared I had lost important data, Frank and his team not only recovered everything but also implemented reliable backup and security solutions to give me lasting peace of mind. Over the years, I’ve relied on their expertise for computer recommendations, system migrations, and data security. Most recently, team member Von seamlessly transferred all of my data from my old computer to my new one without a single issue. He went above and beyond to ensure everything I needed was fully set up and ready to use, and he did so with exceptional patience, professionalism, and attention to detail. Thank you to Frank, Von, and the entire Onsite Computing team for your outstanding service and for always being there when I need you. I highly recommend Onsite Computing to anyone looking for knowledgeable, trustworthy, and dependable IT support.

Amazing customer service. Super convenient to have a live agent on call. Each time we've had one of their representatives come to our clinic we have been met with knowledge, kindness and most importantly a solution to our tech help.
