Tim Castle
Tim Castle has over 30 years of experience supporting computers, including 14 years working in Information Technology departments in the Silicon Valley. Tim started tinkering with computers a little in high school, and quickly discovered a knack for problem-solving and a penchant for achieving business results. Tim has experience working at startups from height of the “dot-com” boom. There, he learned how to move quickly, work independently, and wear a lot of different hats. Since then, he has worked supporting business needs in a wide variety of start-up and SMB environments. Tim has been doing independent consulting since 2002, and have found out how grateful people can be for someone who will show up on time, listen well, and treat them with respect. He hopes you can expect the same from working with him. Mr. Castle holds a Bachelor's Degree in Mathematics & Computer Science from Pepperdine University.

Robby has been working in IT for over 13 years, in environments ranging from startups to Venture Capitols. His specialities lie in supporting desktop, mobile, audio/video, and telecommunication systems. When he is not fixing technology, he loves spending time at the beach or park with his wife and children.
