I am a retired vice president of technology for The McGraw-Hill Companies, where I was responsible for enterprise system upgrades. My retirement came after over thirty years of service in the computer industry.

Recently I have happily discovered LEGO as a way to keep active and engaged in the creative process. I have always been attracted to building things, and the increasing sophistication of LEGO models — especially models of vehicles and machinery — has brought me many hours of enjoyment.
