Rosie's Girls Santa Monica is based on a national program designed to build self-esteem, leadership and physical confidence in middle school girls.  During a three week intensive summer camp, girls go "behind the scenes" and experience what it takes to maintain the city by learning and applying skills in carpentry, welding fire-fighting, tree trimming and other technical trades.
