Dave started his career in engineering in 1994 in an eight-story high-rise commercial building in Rosemont, Illinois as a janitor but, quickly rose to become the assistant chief engineer. There he learned his way around in heating and air, pneumatics, plumbing, and electricity. He has been solely responsible for maintaining and operating and replacing all aspects of commercial buildings. Including upgrading of rooftop units, chillers, cooling towers, automation systems, plumbing systems, VFD upgrades, fire life safety systems and much more. When not managing the building, Dave enjoys cooking and camping.
