Doug Hill has 36 years of experience in the development and management of vineyards in Napa and Sonoma counties. As president of Oak Knoll Farming Corporation, he currently manages over 700 acres of vineyards, cultivating premium cabernet sauvignon, merlot, pinot noir and other varietals for notable wineries including Silver Oak, Ramey, and Duckhorn. Doug also farms 120 acres of his own vines, much of which is utilized for the wine label he owns and manages alongside his family, Hill Family Estate.

Coming home to Sonoma County in 1978, after earning a degree in Plant Sciences at Cal State Fresno and traveling extensively in Latin America, Doug learned the art of vineyard management while employed by Sonoma-Cutrer. After settling in Yountville, Doug managed the extensive holdings of the Jaeger family before starting Oak Knoll Farming. His long tenure in Napa has familiarized him with the Valley's microclimates and soils, enabling him to pioneer new varietals and growing regions; Doug planted the first vineyards in American Canyon and brought the first Albarino to Napa Valley.

As a third generation California farmer, Doug is experienced in finding practical solutions to the challenges that arise in vineyard development projects, and strives to utilize environmentally conscious land management practices.

Doug was a founding board member of Napa Community Bank. He is a past president of the Napa Valley Vineyard Technical Group. He also has participated on the Industry Advisory Board to the Foundation Plant Services at the University of California, Davis, and as a board member of the Napa County Farm Bureau.
