Established in 1990, Charles Varvayanis started out building and selling PC computers and servers in Silicon Valley and quickly transitioned into business computing and networks, including design, installation and maintenance of networks and data centers in addition to servers and workstations.  At the request of our customers, we also began installing and maintaining telephone and radio equipment.  Due to the expansion of the Internet and the advent of advanced remote computing in the late 1990's, we were able to move the business headquarters out of Silicon Valley to the more relaxing Tuolumne County, CA.

Prior to 1990, the founder of Charles Varvayanis operated as a network engineer in Silicon Valley working for Industrial Networking, Inc. (Ungerman Bass/Tandem Computer), Excelan (Novell), Equatorial Communications Company (Contel/GTE SpaceNet) and Apple Computer.
