History

Hunt, Guillot & Associates, LLC was founded in Ruston, Louisiana, by a couple of locals with a passion for both engineering and the wood / lumber industry. At that time, Ruston was only known for its famous peaches and purple-eyed peas. Since opening its doors in 1997, Trott Hunt, Jay Guillot, and Don Plummer have grown HGA into a multi-discipline engineering and project management firm with a staff of over 400 employees.

HGA is organized into business units based on the services provided: Engineering, Pipeline Services, Program Management, EPC Services, and Staffing. We supply services to clients in the oil & gas, refining, chemicals, pulp/paper and wood products, biomass, power, and public works industries.

Over the years, HGA has grown from a single trailer to thirteen locations throughout Louisiana, Texas, Alabama, and New York. Providing services in over 30 states, Canada, and Mexico, we are acknowledged as an innovative leader in the project management and engineering community. HGA has been recognized in the past years by Zweig White, ENR, and Inc. 500|5000 – just to name a few, for its construction management, detailed engineering, and program management services.
