Joe Davis

After graduating from Virginia Tech, Joe began his career in industrial refrigeration over five years ago as a Mechanical Design Engineer, completing system design calculations, 3D models, and construction details for new construction and expansion projects. He quickly began troubleshooting systems as part of an emergency support team for existing facilities while frequently visiting and inspecting them against IIAR, OSHA, and EPA standards. With a team of industrial engineers, he spent several years working to develop and improve processes related to the design, construction, and maintenance of systems. Now, Joe sets up or advances compliance programs for facilities across the country. Joe has seen many different aspects of the industry but will add, of course, that he still has much to learn and is thankful for a strong support team with decades of industrial refrigeration experience to rely on. The bulk of his free time is spent with his family as he and his wife, Renée, have recently been blessed with two sweet baby girls: Sirena and Viola.
