With 40 years of construction experience, Greg has the strong ability to analyze project needs, site conditions, and owner requirements to develop a comprehensive construction plan and schedule. Highly regarded for both his professionalism and his ability to implement complex construction projects, Greg believes his strong scheduling experience and his ability to understanding the individual goals of the owner, tenant, architect, engineer, general contractor, and subcontractor, are vital to his project successes. Greg is a professional communicator who relies on his sharp interpersonal skills to thoroughly understand a project before the first shovel goes in the ground. Greg’s favorite quote is, “Ipsa scientia potestas est “meaning “knowledge is power.” One of his most notable projects was the expansion of reagent manufacturing facilities for Siemens Healthcare Diagnostics.

When not on the field you can find Greg spending time with his family. Greg appreciates the outdoors- hiking through the woods, boating during the summer months, enjoying a round of golf, and skiing down the slopes during the winter season. Greg hopes to someday visit the seven natural wonders of the world including, Great Pyramid of Giza, Taj Mahal, Great Barrier Reef, and Victoria Falls.
