Paradigm Winery, Oakville, Napa Valley
Paradigm Winery, Oakville, Napa Valley

marilyn and ren harris Marilyn and Ren Harris founded Paradigm Vineyards in 1976. Since that time they have grown fruit for many of Napa Valley's most outstanding wineries. They began bottling small quantities of estate wine in 1991. Throughout their ownership of Paradigm, Ren and Marilyn have been tireless advocates for the Oakville appellation, eco-friendly farming, and environmental stewardship.

Heidi Peterson Barrett has been winemaker at Paradigm since its first vintage in 1991. A Napa Valley native and a graduate of U. C. Davis, Heidi is the winemaker for some of Napa Valley's most highly-regarded wineries. Heidi's philosophy in making wines for Paradigm is simple: she feels that she is working with an extraordinary vineyard site that has been farmed impeccably for years. She lets the fruit from this vineyard express its quality and unique terroir with minimal intervention. Heidi and her husband, Bo, have two daughters.

Mark Fasi
joined our team in 2010 as our Director of Production. His winemaking career began after working the 1983 harvest for Beringer shoveling tanks on the grave yard shift. One tank after another, shoveling pomace all through the night, the sun set and then rose. Two years later, Mark moved his family, after attending Humboldt State University, to the Napa Valley to embrace the wine industry.

Mark was first introduced to wine by his paternal grandfather who had immigrated from the island of Sicily at the turn of the 20th century. Mark’s grandmother’s family were vineyard owners, Nero D'Avola wine grapes, as well as citrus fruit and they were also sheep farmers.

Well versed in winemaking and vineyard management Mark’s interest in making wines has always placed importance on the vineyard and all of the subtleties given by the terroir. He has a wealth of experience in organic farming, sustainability, and non-organic wine grape growing in the Napa Valley as well as Alexander Valley, Russian River, Carneros, and in the Santa Ynez Valley. Mark's winemaking approach has always been a "non-invasive", hands-on method. Winemaking is made easy when the majority of your decisions are correctly made in the vineyard.

Mark raises a family here in the Napa Valley. Love for the mountains and the natural world will often lead him deep into those quiet places. He has been known to travel to the Himalaya and India with profound interest in eastern philosophies.

Fernando Diaz Rodriguez
was born in Morelia Michoacan Mexico in 1976.  He first came to the United States in 1992,  He began working for Ren Harris in the spring of 1994, helping to plant many of the vines that are still producing Paradigm today.  He has been an attentive and dedicated student under our previous Vineyard Manager, John Silva, for the last twelve years.  This spring, John Silva retired after 35 years in Ren’s employment.  Ren gave Fernando the opportunity to take his place, and Fernando, after graciously accepting, is now working hard to keep the vineyards here at Paradigm producing the highest quality fruit as possible.  Fernando lives on the ranch with his wife, Hilda, and son, “Fernandito”.
