I have been employed by Dimoco since 1985 and have served as president beginning in 1987. I attended the University of Michigan in the late 70s graduating with a degree in mechanical engineering. After a year of work at Keller Brass as a product engineer, I went back to the University of Michigan and earned an MBA degree in 1983 focusing on Production Operations. Immediately after college, I was employed by a large automotive plastics molder in the Detroit area where I worked in various capacities including quality control manager, production foreman and in-house sales.

My wife and I live in Lowell, Michigan with our two children (when they are home from college). We enjoy backpacking, traveling, golfing, and attending our children’s sporting events.
