Title: President, Virginia Slate Company
Background: Cassel Adamson graduated from Virginia Military Institute in 1996 with a major in both Economics and Business. After graduation, he went to work for the family business: The Virginia Slate Company, located in Buckingham County, Virginia. Cassel was charged with developing and implementing a production line for natural slate roofing, flooring, flagstone, and crushed stone. As with any small business, Cassel wore many hats, making the sale of slate his responsibility as well. In 2000, with the production of slate reduced in Buckingham County. Cassel used his knowledge of slate, and its exceptional qualities, and expanded production to other locations.
