    The Niswonger Foundation was established in 2001 to make a positive and sustainable difference in education in Northeast Tennessee. This dream was envisioned by Scott M. Niswonger, who founded Landair Transport, Inc. and Forward Air Corporation. These companies were the first two Greeneville-based companies to be taken public in the history of Greene County, Tennessee. Jointly, the companies have combined annual revenue of over one-billion-dollars and employ more than 5000 people.
