David Mikosz: David’s involvement with horse training began when he was sixteen, at a neighbor's farm in the small town of Wallingford, Connecticut. From there, his passion training, and particularly for the Arabian horse, has been the inspiration and key to his long standing loyalty to that breed and the people that support it. David has been training and showing Arabians for over forty years. He has worked for some of the best farms in the country, and has trained and shown countless national winners. A licensed judge since 1990, David has judged many shows across the United States, including the Youth, Canadian, Midsummer, and U.S. National Championships, as well as the Scottsdale Arabian Horse Show. Additionally, David is a published author, having written the children's book, Barack's First Great Feat: A Little Arabian Horse Caught In The Middle Of The Israeli-Palestinian Conflict.
