David WIley - Owner

David is a native of Memphis, Tennessee, and a graduate of University of Tennessee with a B.S. in Marketing. For the last 27 years, David has worked as a professional medical device salesman for Henry Schein. In 2000, he made the move to the peaceful mountains of Jonesborough and bought the 10 acres of land that Serenity Knoll now sits on. He gained a passion for contra dancing after learning how in April of 2005, and it wasn't long after this that he founded the Historic Jonesborough Dance Society in January of 2006. His passion for contra dancing and the community surrounding led him to eventually build the pavilion that is now known as Serenity Knoll. 

David is an avid gardener and has a passion for food, traveling, and contra dancing. He is excited to see the possibilities of Serenity Knoll Farm come to life and truly be an asset in our farming, dancing, and cooking community here in East Tennessee.
