Thirty years of surviving and thriving in an area as competitive as dance, and twenty year of community involvement is more than enough of a reason for a party. Let's say a big gala with invited donors who can help balance the budget? A retrospective of what has gone well? Nope. That's not how Joanna Haigood's head works. For her, it's a reason for "Family Day," an open house for the community with classes for the youngest and those a little stiff around the edges. So how about Movement and Storytelling for kids, hip-hop for teens, a Dance Work Out for a sedentary parent, and Circus Art for grandma. She won't swing from the trapeze, but her spirit will get a boost. Each 45-minute class starts on the hour, and food and refreshments are provided.

Sat/6, 10 a.m.-4 p.m., free
