“Growing up on my family’s rice and crawfish farms and later working as an engineer in the oil and gas industry, I learned the value of hard work, precision, and problem-solving. Managing complex well programs and technical projects around the world gave me practical, industry knowledge that I now combine with legal insight to bring a unique perspective to my practice.”

John LeJeune is an associate in the firm’s Maritime Practice Group based in Houston. Prior to joining the firm, he worked for a global technology company as a field engineer on Alaska’s North Slope and in the Gulf of America. He later served as a technical design engineer, where he managed well programs, conducted simulations and risk assessments, prepared technical reports, and coordinated logistics for operations in the Gulf of America.

John earned his Juris Doctor from the Paul M. Hebert Law Center at Louisiana State University in 2025, following a Master of Legal Studies in Oil, Gas, and Energy Law from the University of Oklahoma College of Law in 2020. He also holds a Bachelor of Science in Petroleum Engineering from LSU. His combined legal and engineering background gives him a practical, solutions-oriented perspective that benefits maritime and energy clients navigating complex challenges.
