IT support and business phones across Los Angeles County

From our office in Covina, Tricom supports small and medium-sized businesses throughout Los Angeles County with managed IT, business phone systems, networking and security.

Your local IT team in LA County

Los Angeles businesses can't afford downtime, and nobody wants to explain their network to a different person at a national call center every time. With Tricom you get a local team that knows your setup, picks up the phone, and can be at your office when a problem needs hands on.

Many issues can be fixed remotely, wherever you are. When on-site work is needed, our technicians cover the county, from the San Gabriel Valley and Downtown LA to the San Fernando Valley, the Westside and the South Bay.
