One is only limited by their own fear of the unknown, but the unknown can be learned with the right will and determination. One should not be limited by the box in which they think, but dare to think outside of the box and challenge those around them to do so as well. There is nothing that can not be done, there are only problems that need be solved through ingenuity, imagination, and engineering.

Rob is an NCSEA award winning structural engineer with over 18+ years of experience at his craft. His past experiences have run the maze with respect to types and size and includes all aspects of structural engineering. From Construction Support engineering with High Rise Connection Design for Time Warner Center in New York and Erection procedure design for Motor City Casino in Detroit to Building design of the Thyssen Krupp Hot Strip Mill in Alabama and Re-Design of the award winning Lansing Community College Health and Human Service Careers Building in Michigan, his vast range of experience brings out of the box problem solving and agile team collaboration into all projects. He has directed multiple multi discipline and multi-locational teams in various projects similar to the LEED Gold Tier 3 Mission Critical Data Center for a Confidential Automotive Client in Michigan where agile processes resulted in a high tempo and top performing team. His attention to detail and ability to help his clients find the most efficient designs to help them save cost and time make him a valuable part of any team.
