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.

We have been a client of Onsite Computing, Inc since 2016 and could not be more pleased with the amazing technical support they provide to us. Not only do they provide quick service anytime we are in need; they do it with patience and kindness. In addition, they are very proactive. As they see potential risks to our organization or opportunities to be more efficient; they point it out and give us recommendations. As a small non-profit with limited resources, it’s a blessing to know that we have an organization like Onsite in our corner and advocating for us. We are very grateful and would recommend Onsite to any business or organization in need of computer and IT support!.
