History

Duplantis Design Group (DDG) was founded in 1997 by David Duplantis. Beginning as a small, local civil engineering firm, David believed that exceeding every client’s expectations was the only way to realize long-term success. This philosophy — and a fierce, companywide commitment to following it — grew DDG into a multi-disciplinary regional firm that offers civil engineering, architectural and land surveying services from four company locations. Land surveying services were added in 1999 via a sister company, Acadia Land Surveying, which currently works with private and public clients in Louisiana, Texas and Mississippi. Our architectural group came on board in 2000 and provides services to varied clients in more than 30 states. The DDG corporate office is located in Thibodaux, Louisiana, with branch offices in Covington and Baton Rouge, Louisiana, as well as Houston, Texas
