Duplantis Design Group

In 1997, DDG began as a small, civil engineering firm based in Thibodaux, Louisiana. From the very beginning, we believed that exceeding our clients' expectations was the only way to achieve long-term success. Since our founding, our unwavering commitment to client service excellence has allowed us to grow into a multidisciplinary regional firm with over 150 full-time employees and 7 offices across South Louisiana, Alabama, and Texas. Originally offering services in civil engineering, we have methodically expanded our services to also include architecture, coastal and water resources engineering, landscape architecture, wetlands and environmental consulting, surveying, and project management. Through the hiring of key staff and strategic partnerships with specialty firms, DDG has proven the capability to deliver a wide range of services and support.

Leadership

A strong and cooperative workplace culture is the cornerstone of DDG's success. We recognize that our multidisciplinary teams represent the most critical component of delivering on our promise - to plan, design, manage, and engineer solutions that enhance where people interact and come together.
