Our Story
TN Elite Engineering was built on a shared passion for mechanical design, manufacturing, and solving real-world engineering challenges.
Founders Brandon Griswold and Taylor Sewell began working together at Lincoln Electric Automation (Formerly Tennessee Rand), where they gained hands-on experience designing and developing automated welding equipment, robotic weld tooling, fixtures, and custom machinery for manufacturing applications. Working closely with fabrication, assembly, controls, and production teams gave us an understanding that good engineering doesn't stop at a CAD model—it has to work on the shop floor.
We started TN Elite Engineering to bring that same practical, manufacturing-focused approach directly to our customers. Today, we provide mechanical engineering, 3D CAD design, custom weld tooling, fixture design and build, engineering changes, and manufacturing support to companies that need experienced engineering resources without adding full-time staff.
As a small, owner-operated engineering company, we take pride in being responsive, flexible, and easy to work with. Whether you need help developing a custom weld fixture, making engineering changes, supporting a production issue, or taking a project from concept through fabrication and implementation, we're here to help.
From concept to the shop floor, TN Elite Engineering is built to help manufacturers get the job done.
