Cory began his career in 1978 after graduating from Lawrence Institute of Technolgy with a Bachelors degree in Architecture. He went on to complete a degree in Construction Engineering in 1989 and became a registered engineer that same year. In 2008, after 30 years with a small Michigan Consulting Engineering firm he left to form his own company with a focus on cost-effective design and responsive service. Corian has become increasingly involved in the health of the built environment with involvement in the Main Street Oakland County program, walkable cities and other "smart" growth aspects to make better use of the limited resources we have.
