The Hickox Family, Owners

Red underline

The son of a career naval officer completing his service in Washington D.C., Jon Hickox moved to Fairfax County, Virginia as a young boy in 1982. He always preferred to spend time outdoors hunting, fishing, camping and scouring the woods & fields for Civil War relics and Native American artifacts. Many summers and weekends were spent on a friend's family farm near Chantilly and through working on the farm and spending time outdoors, Jon developed a deep spiritual bond with the land and the people who lived and worked there. He was also deeply affected by witnessing firsthand the slow destruction of farmland associated with the rural crescent that encircles the DC metropolitan area. Through these combined experiences Jon has gained an appreciation and respect for the land, history, and people associated with this passing of "Olde Virginia."

While Jon is a relative newcomer to the wine industry, the core components of business management, respect for history, and an understanding of agriculture are nothing new. In 1993 Jon graduated from Robinson High School and then attended George Mason University to study business, math, and history. While attending college, Jon worked as a project estimator for a remodeling firm where he would learn more about home construction, architecture, and the hard knocks of business.

By his senior year in college, Jon decided to start his own business and spent the next 16 years building his firm into one of the largest remodeling companies in Northern Virginia from the ground up. While attending George Mason University, Jon met the love of his life, Kimberly, who was also a history major. In 2005 they got married and settled in Arlington, VA where they live today with their beautiful daughters, Delaney and Lilly, (who have wines named in their honor) and two dogs Hunter & Mosby.

In 2008, with the real estate market in full downturn, an opportunity to purchase a 21-acre farm at the edge of Fairfax County, perfectly nestled against the Manassas National Battlefield and Bull Run Creek, presented itself. Jon & Kim took a leap of faith and 4 years later (and with a lot of hard work and determination) the winery opened in June 2012. Amongst a sea of urban landscape, The Winery at Bull Run is a working farm winery focused on crafting fine Virginia wines and is a tribute to the history and preservation of 19th century pastoral Fairfax County, taking us back to a much simpler time in our nation's history.
