The city’s arts community has entered “its 2.0 phase,” says Catherine Cuellar, an official at the Communities Foundation of Texas and former CEO of the Dallas Arts District. The arrival of such energetic figures as van Zweden, 55, credited with transforming the Dallas orchestra into one of the best in the country, and Anderson, 59, who devised ambitious programming and reinstated free general admission at the DMA, proves the arts community has turned a corner, Cuellar said.
