    Greg’s multifaceted career spans military service, engineering, construction leadership, and community mentorship. He earned both his B.S. and M.S. degrees in Civil Engineering and Engineering Management from the University of Missouri–Rolla, where he was recognized as an Honors Research Fellow and a Chancellor’s Fellow. From 1986 to 1990, he also played NCAA basketball for the UMR Miners.

    Following graduation, Greg began his career as a U.S. Naval Officer. After completing nuclear power training, he served aboard the nuclear-powered aircraft carrier USS Dwight D. Eisenhower as an officer of the line. During his service, he earned qualifications in nuclear engineering operations, navigation, and combat readiness. His leadership was commended during a critical incident involving a major electrical fire, where his actions helped safely guide the ship to resolution and recovery.

    In 1998, Greg was selected to serve as Assistant Professor of Naval Science and Battalion Advisor at the University of North Carolina at Chapel Hill. There, he taught Naval ROTC and mentored future Navy and Marine Corps officers.

    After completing his military service in 2000, Greg transitioned back to civil engineering. He began working with Fowler Contracting in Cary, NC, gaining hands-on experience in site civil construction as an estimator and project manager. In 2005, he joined The John R. McAdams Company, where he held multiple leadership roles, ultimately serving as Chief Operating Officer.

    In 2015, Greg founded MEC Environmental Construction as a subsidiary of McAdams. Under his leadership, the company grew steadily, and in 2019, he acquired MEC as a stand-alone entity. Today, as President and CEO, Greg continues to guide MEC’s growth in the dynamic site construction sector, serving clients across central and eastern North Carolina.

    Greg is deeply committed to his Christian faith and values the time he spends with his wife of 25 years, Lamarr, their son Walker, and their extended family and friends. He remains passionate about mentoring the next generation, particularly through his involvement with the Society of American Military Engineers. As a Fellow of the organization, he co-founded and continues to lead the curriculum for a S.T.E.M. Engineering and Construction Camp at USMC Base Camp Lejeune, which has trained more than 500 high school students since its inception in 2012.
