I'm a deeply committed tech head who's been playing with a broad range of AV technologies since well before there was something called AV.  I love to know how and why things work, and stumbled on the fact that I have a talent for explaining what I've learned, so I've been teaching and writing about all kinds of technologies for a while now.  I've worked in AV, broadcast, live production, IT, publishing, consulting, and events. I've written the latest versions of the CTS and CTS-I Exam Guides and I'm currently  working on the next Exam Guide for CTS-D.  The most fun part of what I do is research into developing technologies to see how they fit into the future of AV and IT.
