Center for the Arts volunteers: Please remember to wear black or black and white clothes with closed-toe shoes. Please leave time to find street parking as our parking lot is for patrons only. If you're a new volunteer, please come 15 minutes early and ask for the House Manager so we can give you a quick orientation to your duties for the event. When you arrive at the Center (314 W. Main Street, Grass Valley) enter through the front lobby doors and be sure to check in at the volunteer table in the gallery to receive credit for your shift.
