Mayor John DeStefano spoke at TEDxYale. The event, held on February 23, 2013 explored the theme "Solve for y." The speakers were challenged to explain their unique "y," the key ingredient to their work and inspiration, and describe "why" it is significant. More than any other variable, "y" also represents the speakers' common ground, Yale.

Mayor DeStefano has worked hard and successfully to strengthen the academic achievement of public school students, to build a vibrant mixed use city center, a competitive economic base, strong neighborhoods and a community culture of traditional values and social tolerance.
