Ballas, Corky: - Corky Ballas: This story is dedicated to my son Mark Ballas and my experience raising and training Derek and Julianne Hough, who lived with us for several years in London, England. Many of you have seen all of us on the famous hit show Dancing with the Stars. They learned how important work ethic, discipline, and setting goals is in life, and look at them now! My wish is that all children will be inspired to adopt these important life skills in everything they do.
