Tom and Jennie Hendrix started Southeastern Fly Ash Company (SEFA) at their kitchen table in Snellville, Georgia, in April 1976, with the goal to recycle fly ash for use in the construction industry. Tom and Jennie founded SEFA on the principles of integrity, honesty, service and hard work. These same principles remain the core foundation of SEFA today. The Company has grown steadily and diversified extensively with each successive decade since 1976 while maintaining its innovative, entrepreneurial spirit. As SEFA expanded to further contribute to customers’ success and environmental stewardship, services were added in transportation, construction, and engineering. Today, SEFA is composed of Fly Ash Sales and Operations, Advanced Technologies & Projects, SEFA Transportation, SEFA Industrial Solutions, and Spherix® Mineral Products. SEFA is a privately-held company based in Lexington, South Carolina.
