Don St. Pierre, Co-Owner & Executive Chairman

In 1996, Mr. St. Pierre co-founded ASC Fine Wines, which he built into Greater China's leading importer of premium and fine wines. In 2010, he sold the company to Suntory Holdings. At the time of the sale, ASC had 1,200 staff in 26 offices, and over 100 exclusive importing relationships with elite international wineries. After selling ASC to Suntory Holdings, he stayed on as CEO until 2012, and remained as a Board member and Senior advisor to Suntory Wine International until December 2015. Don is the recipient of numerous wine industry accolades, including being named No. 7 on Decanter magazine's 2011 Top 50 global wine industry power players and being selected by Wine Enthusiast Magazine as the 2011 International Man of the Year. In 2012 the French Government also awarded Don the degree of Knight in the French Ordre du Mérite Agricole.
