City of Grand Terrace

City of Grand Terrace

When the city was looking for a new IT support company, Onsite Computing was the only professional IT company that had a proven track record of successfully supporting the IT needs of government and businesses since 2001. Plus, they provide us with all the IT services we needed under one roof. Since taking on our IT management, Onsite Computing has proved they are skilled at handling the diverse IT needs of the City of Grand Terrace. We trust them and highly recommend them to other organizations.

Stronghold Engineering, Inc.

Stronghold Engineering, Inc.

We started working with Onsite Computing in 2017 and we are glad we made the switch. Thanks to Onsite Computing’s IT service, the entire burden of computer support is taken off our back, and I don’t have to worry about security threats or downtime. Now we are getting regular Microsoft updates, virus updates, spyware is being scanned and removed, and our backups are being taken care of. It’s really helped speed up our network, our programs run better, and we don’t have the recurring problems that we had in the past. Frank and his team are the best.

Unilever

Unilever

In 2008, Unilever was fortunate to learn about Onsite Computing. As Unilever’s plant in Corona dealt with the same computer issues that plague many businesses. From IT support to disaster recovery, maintenance, and programming Onsite Computing handled it all with ease. They had solutions for all of our IT problems and their customer service was EXCELLENT. Allowing their team of highly qualified experts to manage our computer network afforded us more time to do what we do best at Unilever…meeting everyday needs for nutrition, hygiene and personal care. We would, and we have, referred them to other businesses that are looking for a quality, reliable, and affordable IT Management Company.

US Continental

US Continental

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.

Onsite Computing was able to step in to assist with our corporate IT services with ease. From desktop support to specialized server deployment, Onsite is reliable and experienced. Their team is pleasant to work with and very responsive. For the cost of a single support person, we got an entire IT team at our disposal which covered every aspect from project planning, deployment, and management. They've not only taken care of our technical issues but have done it with a personal touch; great follow-up and communication.

Onsite Computing has been a great asset to OC Elder Law. They have moved our server into the cloud and helped us create a uniform, easily assessed, network environment. Setting up multiple locations for us was stress free, as they coordinated the IT equipment purchases, installation, and management. They’re a pleasure to work with and we recommend them.
