About Us

Jim HeadshotJim McMahon

Co-founder, Owner, Winemaker

Jim was raised in Sonoma and attended college at Cal Poly, San Luis Obispo. Jim began his career in the wine industry at Kenwood Vineyards & Winery under the legendary Mike Lee and moved up the ranks to Assistant Winemaker.  After almost a decade at Kenwood, Jim made the move over the hill to the Napa Valley. He started as Assistant Winemaker and was eventually named Winemaker at Luna Vineyards followed by General Manager and Winemaker at William Harrison Vineyards & Winery. Jim is currently on the winemaking team for Coppercane producing the Belle Glos and Meiomi Wines.

In 2002, Jim met the love of his life, Courtney, whom he wed. In this union, Jim also met his business partner, Tom Keith, Courtney’s father. They quickly realized they shared a passion for wine in Tom’s cellar, and Athair was born.

Jim’s approach to making wine begins with quality fruit and solid winemaking skills. These fundamentals are critical to creating a good wine. However, to Jim, combining them with passion and pouring his heart and soul into the process is how a good wine becomes superb.

 

Tom Keith

Co-Founder, Owner

In 1977 Tom discovered the Threshold of Heaven: Sonoma Valley, California. Over the next thirty years, while raising his three children, he honed his skills as an amateur winemaker in his backyard.

After 34 years of owning and operating an international Men’s Apparel business, Tom retired and followed his dream into the wine industry.

Tom assists with sales for Athair. When he is not working Tom can be found on the golf course with his wife, Jamie, playing with his seven grandchildren, or walking his dog, Maggie.

Juan & Renee LorenzoPicture for Athair

Proprietors 

Renée and Juan are both passionate about wine. Juan because he is a native of Spain and Renée because she is a second generation Sonoman and both locales produce spectacular wines. They met while college students in San Francisco and married soon after. San Francisco was home for a few yeas but they yearned for the climate and casual ambiance of the beautiful Valley of the Moon, where they were spending nearly every weekend. Finally in 1973, they decided to relocate to Sonoma. Over the years, while both had other careers, they always talked about becoming involved in the wine business.

Juan and Renée have been friends of the Keith and McMahon families for a long time and were given the opportunity to become part of the Athair organization. They are avid supporters and roving ambassadors of Athair Wines.
