Before purchasing the Vrede en Lust farm in 1996, Dana was involved in the informational technology industry. His company, Workgroup Systems, was the first South African company to have a distribution relationship with Microsoft post the sanctions era. Workgroup grew to become the largest distributor of software in the country by 1996, at which point he sold the distribution, training and consulting components of the business.
Buys was chairman of Frontrange when it listed on the JSE in 1997. Since selling Frontrange Solutions in December 2005, he is dedicated to making a success of the Vrede en Lust wine business.
In 1996 he began his new venture in the wine industry. He replanted entirely new vines in relation to the unique soil of each block of land. Dana also restored much of the historic building back to their original status. He completed his post graduate studies in Wine Business through the University of Adelaide. He is heavily involved in promoting the South African wine industry as a whole.
Dana married Anneke Louw in June 2008. They now live back on Vrede en Lust in a new house a bit further up the farm. Dana has two daughters; Jessica, Sarah, from his previous marriage and little Anni is the new addition to the Buys family!
