In the waning days of his second term, Mayor Michael Nutter was named 2015 “Champion for Change” by the National League of Cities for his work in reforming the juvenile justice system in Philadelphia.

Specifically, Nutter was recognized for the Philadelphia Minority Youth Law Enforcement Curriculum he helped city law enforcement implement in his first term, and for helping to create Cities United with New Orleans Mayor Mitch Landrieu in 2011. The latter partnership, dedicated to reducing violent crime in black male populations, has been supported by 62 mayors.

“Mayor Nutter has had a tremendous impact on juveniles in Philadelphia,” said Philadelphia Department of Human Services Commissioner Vanessa Garrett Harley. “He has aligned multiple city agencies and initiatives so that they all come together to make a deliberate impact on juveniles in Philadelphia.”
