Fun facts about Greg

Greg has always had a passion for construction. He grew up in a custom home builder family and worked on his first construction project while still in high school. He continued to work as a framing carpenter for several custom home builders before attaining a summer position at Mark Carstensen Construction. Greg graduated from the University of Wisconsin – Stout in 2000 with a bachelor's degree in construction management. He was then hired by Carstensen Construction as a carpenter and quickly advanced through the ranks, becoming a Residential Expeditor before moving to the commercial division of the company where he worked as a Commercial Superintendent, Project Manager, and then Division Manager. In 2011, Greg purchased the assets of Mark Carstensen Construction, and formed the new company, The Carstensen Group, where he serves as CEO. As the company experienced growth, the company was divided into two divisions that are managed and staffed separately. In 2013, the company name was changed to The Marso Companies with Carstensen Homes for the residential division and Marso Construction for the commercial division. Greg's enthusiasm and commitment to the construction industry have brought additional success to both the commercial and residential divisions of the company, which has gained more new and repeat customers than ever in the past, including one national developer.
