Michael Castelli

Michael Castelli

Project Manager
Greater St. Louis Area

Michael began working in the construction business during high school when his dad, jointly with his mom, ran a successful excavating and new home construction business. Well known in the Edwardsville/Glen Carbon area, Castelli Homes and Excavating earned a reputation of offering high quality homes at reasonable prices. Michael has continued to work side by side with his father since then, most recently by running a restaurant. He learned estimating and acquired in-depth knowledge of construction products while he worked at a local lumberyard, but left there to join the family business.

When he’s away from the job, Michael enjoys riding his Harley, playing pool and spending time with his wife, Lauren, and their two young sons, Sebby and Gus.
