Tony MacDonald started his career in the security industry in 1993 as an Electronic Access Control specialist. Designing, and then maintaining systems for companies throughout the Bay Area.

In 1999 he transitioned into computer consulting. Starting out in basic pc repair and troubleshooting, he then moved into network infrastructure design and implementation. Throughout all of this, he made an effort to get a copy of every Microsoft operating system well before release for testing to be sure he was able to provide support for his clients upon its release.

In 2008, his IT firm opened a special effects and post production studio and secured contracts for several major motion pictures as well as commercials and music videos.  From 2008 through 2012 he worked to support his clients while also maintaining studio operations. Late in 2012 it was time to refocus, so Tony moved to RenIT.
