Mission & History
Stone Environmental was founded in Columbus, Ohio in 1974 as Sparham & Sparham Consultants. In October 1999 we became known as Stone Environmental and in December 1999, the firm acquired certain assets of Shaw Weiss &De Naples Engineers and Environmental Scientists of Dayton, Ohio, which was established in 1968. In 2014 Stone Environmental became 100% woman-owned and is certified as a Disadvantaged Business Enterprise (DBE).
