Greg came to THB in 1999 with over 20 years experience in the construction industry. He has been a superintendent for 36 years and uses his strong background in large scale commercial projects with large staffs to aggressively manage schedules and budgets. Greg received the 1999 Excellence in Construction award from the Associated Builders and Contractors for his work at the Mother and Infant Care Center at the National Naval Medical Center in Bethesda, Maryland. His experience in supervising all construction trades and his calm, efficient management style enable him to be a construction leader of great effectiveness.

His ability to gain management and supervisory positions of increasing responsibility led him to open his own design-build timber framing company.

Running the high mountain trails and rafting the Snake River are two of many activities in the summer for Mr. Dalby.
