Marc Marchant

Title
LS3P

Marc Marchant serves on LS3P’s board of directors, leading the 502-employee architecture firm ranked No. 11 on Building Design + Construction’s Top 180 Architecture Firms list for 2025.

A Clemson University graduate with a master’s degree in architecture with concentration in healthcare design, Marchant guides the firm through major projects including Clemson University’s Veterinary School, Charleston International Airport parking garage, and the LEGO U.S. manufacturing facility.

“Don’t get the fat head,” he says, recalling his father’s advice about remaining humble despite success.

Marchant identifies talent, technology and transitions as the industry’s most pressing challenges, embracing artificial intelligence as a tool to enhance creativity while planning for generational succession through the firm’s Evolution30 strategic plan.

His leadership extends beyond architecture: he chairs the Trident CEO Council, serves as vice chair of Porter-Gaud School’s board of trustees, and sits on Clemson University’s Board of Visitors and the Charleston Metro Chamber of Commerce PAC board.

His first job installing in-ground irrigation systems taught him reliability and strong work ethic. A deliberate daily reader who stays informed through newspapers, Marchant defines success through fostering environments where team members feel inspired and empowered.
