Originally from Pennsylvania, John has been a hospitality professional for almost 40 years. He has spent the last 25 years and counting, working in Napa Valley. John was the Sommelier & Manager at Domaine Chandon’s restaurant in Yountville, and the Director of Wine Education at Shafer Vineyards in Stags Leap District.
