Rodney Strong Team

Our approach is for the grapes from each vineyard and growing region to express their intrinsic character in the special wines we craft. Gentle handling, careful use of barrel and stainless steel fermentation, and proper oak aging enhance the natural characteristics of the fruit.

Tom Klein


A fourth generation California farmer, Tom earned a business degree from Stanford and spent the first part of his career as a management consultant at the San Francisco office of the prestigious global management firm McKinsey & Company. One project during this time was evaluating a small winery in the Russian River Valley called Rodney Strong Vineyards and, in a chance meeting, he was introduced to founder Rod Strong and winemaker Rick Sayre. Already developing an interest in wine, this encounter planted a seed that would grow into a lifelong passion.

Justin Seidenfeld serves as Winemaker for Rodney Strong Vineyards, the iconic Sonoma County Winery that was founded in 1959 by namesake Rod Strong. Justin’s winemaking career began in Sebastopol, California, where he was an intern at Iron Horse winery in 2005. He quickly rose from cellar hand to taking on winemaking responsibilities which led to a position in 2006 at the venerable Robert Mondavi Winery in the Napa Valley.

As a harvest enologist at Mondavi, Seidenfeld walked some of California’s premiere vineyards and gained a comprehensive understanding of quality land and viticulture. Continuing on to become an enologist, he took that experience into winemaking and supervised the winemaking of Estancia, Clos du Bois, Simi, and others within the Constellation portfolio. Additional responsibilities included overseeing small lot Cabernet Sauvignon and Pinot Noir winemaking.

As to his inspiration to a career in winemaking, Justin notes, “people recalling the occasions that wine makes better and memorable is the reason I make wine. Hearing about how and when someone enjoyed a wine I made inspires me.”

Greg Morthole


Raised in Sacramento, Greg Morthole attended the University of Wyoming, where he earned a B.S. in Natural Sciences. He entered the wine industry as a Laboratory Analyst at Vinquiry in Windsor, California, then moved to Chalk Hill Winery in 2003 to become an Enologist.
