What do Mariah Carey and Natalie Portman have in common? They both attended Usdan! Usdan Summer Camp for the Arts is a summer day camp on Long Island. Set on a sprawling and wooded campus, it offers campers all sorts of arts immersion and plenty of good old summer fun like swimming and archery and ice cream. Built in the 1960s, the camp and its facilities have a terrific utopian vibe. We're proud to still call them a client after all these years.
