Yesterday I decided to finish writing my paper and wrote an additional four pages and my computer suddenly ran into a problem and automatically shut down. The system should have auto saved everything since it's programmed to save every 10 minutes, but it was all gone and all I could see was the two pages from the days prior once my computer started up again. I was in panic mode and did not know what to do. Thank God I came across this yelp page and called Ron. He did some troubleshooting, trying a few different things after remoting into my computer. He was able to relocate my lost document and I felt like I won the lottery. Thank you so much! Saved me hours

California Security Pro…read more Home security has never been my favorite topics, at first a bit confusing there's network apps, motion sensors and connected door alarms all of which seem to work flawlessly together. We called two places ADT corporate and California Security pros.    Bill Wood approached us in August 2016 after buying new house. Many of us have had that one teacher who makes it all click together they are often energetic and fun seemingly always at the top of their game. Bill's smile, genuine personality and willingness to teach difficult subjects to us made him the clear choice a 2nd time this summer when we installed ADT at our local Napa Business. We feel great knowing who to call and who to let in our house when our batteries need replacing. Communicating via text message and follow ups afterwards were "Better than Expected" Thank you!
