Krista Nightengale began her career in journalism before stumbling into the fascinating world of urban design. Today, she serves as Executive Director of Better Block, an international nonprofit that helps communities turn civic engagement into visible action by testing ideas in the real world. Over the past decade, Krista has worked alongside neighbors in more than 145 communities to rethink streets, transform underused spaces into places people want to gather, and remove the barriers that keep communities from making the changes they want to see. The work has helped calm traffic, strengthen local economies, and, in some cases, reduce crime—but the outcome she cares about most is turning strangers into neighbors.
