The Houston Ballet, operated by the Houston Ballet Foundation, is the fourth-largest professional ballet company in the United States. The foundation also maintains a ballet academy, the Ben Stevenson Academy, which trains more than half of the company's dancers. As of 2011, the Houston Ballet's endowment at more than $55 million is considered among the largest endowments held for a dance company in the US. The company produces over 75 performances each year and consists of well over 50 dancers. In 2003, Australian choreographer Stanton Welch was appointed as Artistic Director and has created numerous works for Houston Ballet. The Houston Ballet calls the The Wortham Theater Center home. The Wortham was designed by Eugene Aubry of Morris Architects and built in 1987.
