Much of the orchestra’s present success is credited to Janna Hymes, the music director for the past 15 years. “When I came to Williamsburg, I had a vision artistically,” says Hymes, “and I know we got there. The orchestra is now at a completely different level. The musicians are more committed to their work of making great art. We’ve expanded the educational concerts, and we made our first international presentation with a concert in Bermuda.”
