Scott Bernstein owes his start as a game changer to a dog bite. Actually, quite a few dog bites. Not one of which was inflicted on his own person.

The year was 1974. Bernstein, then a Research Associate at Northwestern University’s Center for Urban Affairs, was asked a “deceptively simple question”: How do you make people healthier? The request came from the Christian Action Ministry (now Bethel New Life), a consortium of churches on Chicago’s West Side.
