"David is fun, creative, dynamic and extremely seasoned. His business sense saved us at a time of sudden and unexpected transition. Without David’s work with our winery we would have lost real ground and precious momentum, instead we came through that transition in a stronger place than we’d ever been and were positioned for positive, healthy growth. It was AWESOME."
