4-H

"Remember, it's Vegas rules, guys. What happens here, stays here," says Alexander Chan to a room full of giggling high school teenagers as he goes over the ground rules for a workshop all about healthy relationships.

Chan's background is in marriage and family therapy. Now he's an educator with 4-H in Prince George's County, Md., where he leads a youth development program, through University of Maryland Extension, to help local teens understand and cultivate positive romantic partnerships.
