Look up MedicZero, Inc. It's a nonprofit run by Rutgers students/alumni who are EMTs, they teach bystander CPR classes which teach CPR and stroke awareness. You don't get a certification, but you learn what signs to look for, how to perform CPR/use an AED, how to direct other bystanders to help & call 911 while you perform CPR. My local library/OEM department organized the class and about 50 of us residents showed up. It was a real eye opening experience and I feel confident about performing CPR should someone need it. (The Good Samaritan law protects bystanders performing CPR who aren't certified).

If you're on Instagram, you can find them at @mediczeroinc or @mediczerorutgers

Highly recommend contacting them to find a class or set up a class for your town!
