405 Computer Service (formerly Patriot PC Solutions) is based in Fountain Valley, California. Owned and operated by Mark Oster since 2001, we have been servicing many networks all over the county. These businesses have included:

Many clients are clients I have retained since I have been in business and have stayed with me more than 10 years or more. In my cliebtel I have learned to modify and maintain many proprietary software packages. There are literally dozens of medical and dental office software packages that I have had to keep up with and especially when it has come to Microsoft Windows updates that have modified those packages.

I offer remote support at just a phone call away.
