In 1956, two visionary engineers, William A. Thompson, Jr. and John W. Litton, founded an engineering company in the southwestern part of Virginia, which would proudly serve its clients for decades to come. Their very first projects served the region's important coal industry. Over the next 40 years, hundreds more projects followed, as Thompson & Litton expanded its service area to five Mid-Atlantic States. In order to serve these areas, Thompson & Litton has grown from its original staff of seven people to an organization that has over 100 employees and offers engineering, environmental, architectural, surveying and planning services. From the beginning, Thompson & Litton emphasized the quality and commitment of its people.
