Our History
In 1997, David Duplantis started DDG 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. In the 25 years since our founding, our unwavering commitment to client service excellence has allowed us to grow into a multidisciplinary regional firm with over 110 full-time employees and 7 offices across South Louisiana, Alabama, and Texas – Thibodaux (headquarters), Covington, Baton Rouge, New Orleans, Lafayette, Mobile, and Houston.
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, and surveying. 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.
