Andy was a deeply committed tech-head who had played with a broad range of AV technologies since well before there was something called AV. He hungered to know how and why things work, and stumbled on the fact that he had a talent for explaining what he'd learned, so he taught and wrote about all kinds of technologies, in books, magazines, manuals, seminars, and online. He worked in AV, broadcast, live production, IT, publishing, consulting, and events. In the early 2020s he wrote the new editions of the CTS, CTS-I, and CTS-D Exam Guides. The most fun part of what he did was the research into developing technologies to see how they could fit into the future of AV and IT. Most recently, he became heavily involved in initiatives to improve the sustainability of the technologies we use in the audiovisual industries.
