Since our founding in 1943 by Ralph Hill and Gordon Gray, Grayhill has been committed to providing top-quality interface solutions for a wide range of applications, including healthcare, military and off-highway as well as tailored standard products and value added assemblies. We take pride in having been the first in our field to achieve ISO 9001 certification. More recently, we were among the first to be certified to the SAE AS9100 Revision D Quality Management System (QMS) for defense organizations.
