Fontana's economy runs on trucks, steel and healthcare: the Auto Club Speedway corridor, massive distribution parks along Sierra and Jurupa, Kaiser Permanente Fontana and a wave of new industrial construction.

Why Fontana businesses choose a local IT partner
Remote support solves most problems, but a failed switch, a new office build-out or a server that will not boot needs a technician in the room. Providers based in Orange County or Los Angeles quote "same week." Quantum dispatches from Rancho Cucamonga and quotes same day. That proximity also means our engineers already know the carriers, buildings and business parks in Fontana, which shortens every project.
