In 1998, already a seasoned performer despite being a minor, he was given a special dispensation, and was permitted to perform in the senior division of the USA International Ballet Competition (USAIBC). Thomas won the gold medal, and at 16 years old became the youngest to win in the senior division, beating Mikhail Baryshnikov's previous record age of 18. The win opened up new opportunities for the dancer. Later that year, he and three other dancers, including Adrienne Canterna, originated the piece for the tenth season of The Vail International Dance Festival. The couple performed at the festival again in 1999.
