Hark Laboratory is an Independent laboratory established in 1968 by a group of local workers, Hinkle, Armstrong, Ramsey, and Klein.

     During this time, we have undergone many changes, from starting in a small block building down the street to moving to our present location in 1978. In 1980, we added more testing equipment and machining capabilities. Then had to expand, building a separate machining facility and remodeling the main building in 1994.     With the last of the original owners, Edward Ramsey, passing away in 2016, Jerry Ratliff continued to run Hark Laboratories until his passing in 2018. His wife, Lynn Ratliff, now the owner, keeps her departed husband's legacy going with the help of the general manager, Cabot Schultz.
