Mark started with The Kachele Group in 2003 and has continued with the firm through the transition to Keystone Structural Solutions and to the present day. He is currently a registered Professional Engineer in 7 states. He has over 3 decades of experience as a professional engineer. Mark enjoys the challenge of renovation projects in existing buildings that often get very complicated and require strong engineering skill as well as sound engineering judgement. Some of his favorite projects include the renovation of the existing Sewall Center into the new UPMC Events Center on the campus of Robert Morris University as well as 151 First Side in downtown Pittsburgh.

While not at work, Mark enjoys spending free time with his family, and keeping tabs on the local sports teams. He is also a long suffering fan of the University of Pittsburgh football programs, and enjoys attending their games, both home and away, as much as possible.
