2025 40 Under 40: Chad Riggs, 38

Engineering Team Leader, Principal, CMTA Inc.; MS, Mechanical Engineering, University of Louisville

Riggs’s passion for sustainability drives him to deliver the most innovative, efficient and cost-effective solutions for his clients. He worked to maximize the full potential of guaranteed energy savings contracts (GESC) at Warren County Public Schools in Bowling Green, Kentucky. Managing a $30 million GESC, Riggs led geothermal renovations at five schools, including completing the first zero-energy school funded by a GESC. In 2021, after successfully completing CMTA’s first project in Virginia at Loudoun County Public Schools (LCPS), Riggs was promoted to partner and team leader in the region, where he remained instrumental in supporting LCPS. Notably, Riggs helped convince LCPS staff to adopt geothermal systems for two HVAC renovations, one of which won an ASHRAE International Technology Award. In every project, Riggs has served as the single point of contact for the client throughout all stages, including conceptualization, design, implementation, commissioning, measurement and verification. In addition to managing projects, he is actively involved in strategic planning, fostering connections between offices, driving business development, expanding cross-selling initiatives, improving processes and enhancing quality control. From a young age, Riggs was taught to help others in need. Each year, he participates in initiatives like the Red Cross blood drive and Dare to Care food drive. His favorite activity outside of work is playing golf and he makes time to connect with nature whenever possible. He and his family enjoy hiking, kayaking, riding bicycles and visiting state parks. His afternoons and weekends are typically filled with laughter, dance and swim lessons and numerous other activities with his three young children.
