Castro Computer Services began business in 1999. As a small business in San Francisco Bay Area AND Marin we can’t compete with the big box stores on prices BUT we can compete with our dedication to excellent customer service! We rely on word of mouth referrals, not fancy advertising or marketing. We work with pride and integrity, not profit-margin or up-sells. We keep almost NO inventory of parts so we can find the solution that works best for YOU.

We are a small family business specializing in providing computer solutions for individuals, and small and large business alike. Some of the services we provide include data recovery, data backup and transfer, spyware and viruses, hardware and software issues and upgrades. We build custom PC desktops to your specifications. The difference between our custom build pc's and those "off the shelf" are the internal parts. We use brand name, tested and quality rated parts from the best manufactures and suppliers; those known to pass rigorous diagnostic and fitness tests to extend the life of your system as opposed to being built for planned obsolescence. We have an internet bar: $.20/min computer time, $.20/b&w prints, $1/color prints, fax and scan capabilities. Our internet bar computers consist of one XP pc, one Vista pc, and one Leopard Mac, and are free to customers while your computer is being worked on. Stop by and check us out!
