Winemakers

With over 35 vintages under his belt, Mark is Sr Vice President of Winemaking and oversees all winemaking and cellar operations. He began his career in 1977 with Pacific Land and Viticulture and then went on to Sebastiani where he became the Director of Winemaking. Mark even started his own company in 1986, Global Vin and Beverage, where he was instrumental in the launch of the Vinterra and Viansa wine brands. He holds his undergraduate degree from UC Berkeley and a graduate degree in Food and Science/Enology from Fresno State University. He loves to travel and, when it comes to wine, he’s seen it all!

Adam is one of our beloved Winemakers at O’Neill. He supervises all harvest activities which include receiving and crushing grapes, supervising barrel and tank programs, and creating bottling blends. He earned his Bachelor of Arts in Psychology at California State University Long Beach before going on to earn his Master of Science in Clinical Psychology at California State University Fullerton. He had previously worked for Peachey Canyon Winery and Chronic Cellars in Paso Robles and, after completing coursework in enology and chemistry, Adam found his way back to wine. When he’s not making wine, Adam enjoys backpacking, surfing, fly fishing and running with his wife and labradoodles.
