Wan Kim's first experience with Smoothie King was while studying at the University of California at Irvine in 2001. Wan was impressed with the high-quality and healthy products and by Smoothie King's overall approach to health and wellness. In 2003, after moving back to Seoul, Wan opened the first Smoothie King store outside of the United States. He found that Koreans loved what Smoothie King had to offer as much as he did. Wan proceeded to grow the Smoothie King Brand in South Korea to currently more than 130 locations.
In July 2012, a company Wan created, with backing from Standard Chartered Private Equity and National Pension service of the Republic of Korea, bought Smoothie King from founder Steve Kuhnau.
Smoothie King has potential for tremendous growth in the U.S. and international markets. Smoothie King is now operating more than 800 stores around the world and is expanding aggressively in the U.S., Korea, and the Middle East.
