"Skip / Shannon,

I just wanted to let you know that you far exceeded my expectations on the cabling job here in Anaheim. The work was fast and professional all the way through with minimal impact to the office staff. I’m also happy to report that we’ve encountered no cabling issues at all since we went live on the new connections. Outstanding!"
