Duplantis Design Group, PC (DDG) was founded in 1997 by David L. Duplantis, P.E. Beginning as a small, local civil engineering firm, David believed that exceeding every client’s expectations was the only way to achieve long-term success. This philosophy and a company wide commitment has grown DDG into a multi-disciplinary regional firm that offers civil engineering, architectural and landscape architecture services from five company locations. The DDG corporate office is located in Thibodaux, Louisiana with branch offices in Covington, Baton Rouge, Houma and Houston.
