Glyph

Mark Ravenhill is a lifelong lighting nerd in a suit when needed and a translator the rest of the time. He cut his teeth at Martin Professional, helping steer touring/theatre products in the MAC era, then jumped to GLP in 2009 to build the US presence and champion fixture design that serves the song, the camera, and the crew. He currently leads US sales and marketing from Nashville. Colleagues know him for the same north star he’s had since day one: lights that earn applause without stealing it, reliable optics, honest output, and looks that read from the pit to the nosebleeds. If there’s a through-line, it’s this: connect makers to designers, turn feedback into better tools, and keep the magic repeatable night after night.
