About Us

our story

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.

As the “SERVICES” section above illustrates, we deal with all types of systems, devices, configurations, and brands of computers, peripherals, mobile, audio-visuals and networks there are. 

As the “TESTIMONIALS” section shows, our clients LOVE US! Give us a chance to earn your love 💕  too!
