Chris Furhman

Chris Furhman

About Chris

Chris Fuhrman started his professional career as a music recording engineer in the early 90’s working on projects for Major label record companies. As a trained and skilled audio professional, he was one of the first engineers to embrace computers for recording music. As the music business changed so did Chris’s focus. His path evolved into becoming an Apple technology expert, serving clients not only in the arts, but also in architecture, construction and in the health care field. Though Chris started his IT expertise as a Mac specialist he has now branched into a hybrid of Apple, PC and Cloud based systems & networks.

Chris’s ethos as an IT manager is to empower his clients thru technology. Being a Mac user before becoming a trained computer technician Chris understands that technology needs to support and enhance your individual work processes rather than be a rigid system that one has to conform to. Chris’ focus is to always bring his clients desires into reality, and is proud to be a part of the Streamline family.
