Brian Willis
Field Service Supervisor

An 8-year Martin Group veteran, Brain Willis got his start in the copier repair business in 1985. As one of our Senior Service Technicians, he has fixed it all – from old analog copiers to today’s complex production printing systems. Brian holds two Gold Seal awards with Konica Minolta. The Gold Seal award is the highest recognition Konica Minolta presents to students that attend a certified training course.
