William Hoff is the new director of the North Carolina Zoological Park. The park is now under development on the nearly 1,400-acre Purgatory Mountain site near Asheboro in Randolph County. Hoff has worked with the Lincoln Park Zoo in Chicago and the Cincinnati Zoo. Before taking the North Carolina position, he was director of the world-famous St. Louis Zoo. He was attracted to North Carolina because of the challenge to build the ideal zoo from scratch.
