JUST WEEKS BEFORE SUMMER BREAK, the football field outside Saint Mary’s High School hummed with the metronomic thump of CPR dummies as at least a dozen hands practiced chest compressions at once.

Most at this recent Saturday training were students and staff from the north Stockton school, all taking part in hands-on CPR training demonstrated, in part, by one of their peers, 16-year-old Heather Freligh.
