Marty Brenneis started his path in the AV world in 8th grade when the Berkeley School District issued him a Sony black and white camera and portable reel to reel video reorder to shoot material for the district. In High school he did his first AV integration job by building a TV studio for the school. That also introduced Marty to the world of theatre and the life of a stagehand.

After a couple of years at the College of San Mateo Electronics Technology program he landed at Industrial Light and Magic in San Rafael to work on The Empire Strikes Back. At ILM Marty was part of the team inventing many techniques and custom equipment used for visual effects production. During that time Marty would also work with a small team at ILM who were working out ways to do visual effects with computers. For 26 years Marty floated between various teams in the Lucasfilm Group providing technical support to artists in many fields.

Along the way Marty also got involved in webcasting and that took him back to the video production roots. As a member of IATSE Local 16 he has worked in many different technical positions for tradeshows, theatrical production and film production. In 2016 Marty was the lead engineer for the webcasting for the Democratic Convention in Philadelphia. 

In joining DCA Marty brings years of operating experience to the design process. He has the attitude that he might actually have to sit in the chair and do the job that the systems are being built for.
