1979 graduate of National Camera's resident camera repair school. I worked as a technician for a large Denver camera service center performing repair and service both in and out of warranty for over 38 brands of photographic equipment, accumulating over 5000 hours of bench time. As a self-employed contractor and general technician, I accumulated another 40,000 hours of bench time working on 110mm, 35mm, medium format film cameras, lenses, flash, enlargers, timers, paper processors, long roll portrait cameras and more. I have worked on most equipment made. The challenge of successfully taking anything photographic apart and reassembling it into an accurately working piece... and you could not tell I took it apart, was enough for me. I do not work on studio flash. I don't care much for Alpha, Bronica S2 S2a, Leica R, Contaflex cameras and a few others. Generally, I do not work on customer equipment anymore. I have plenty of my own cameras to maintain as well as few collections for other collectors.
