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.

Kathleen Fleming -  guest faculty

Kathleen Fleming is the owner/founder and Mama Bear of Majestic Unicorn, an Asheville, NC based lifestyle brand dedicated to nourishing women. Kathleen practices and teaches lost healing arts to women who are seeking nourishment on the physical, psychic, emotional and soul levels. A graduate of The Institute for Integrative Nutrition, with a B.A. in Early Childhood Education, and four children (two biological, two step), Kathleen is deeply passionate about mothering, and providing approachable, pleasurable healing tools for women during every life phase. Kathleen’s humble beginnings in the kitchen began in fourth grade, when she made a “stew” for her mother comprised of raw beets and chicken bouillon.  (Mama Gail acted like it was the BEST thing she’d ever tasted!)  It was the beginning of a life-long love affair with flavor, texture and fragrance. As a graduate of Mama Gena’s School of Womanly Arts, Kathleen has learned to integrate pleasure into every pocket of her existence and brings this mindfulness to her work.  She scoffs at the notion that, as women, we must compartmentalize our sensuality, and instead advocates for a holistic approach to engaging with and expressing, our extremely fertile, luscious creative potential. Kathleen has been a guest teacher at the Southeast Wise Women Herbal Conference, and her writing has been featured by HuffPost and numerous other media outlets. She teaches classes all over Western North Carolina and Eastern Tennessee, and has a private practice in Asheville, North Carolina. Her website is
