In Chapter 1 of 9 in her 2011 Capture Your Flag interview with host Erik Michielsen, non-profit founder and executive Louise Davis Langheier shares what she feels defines social entrepreneurship. She defines social entrepreneurship as the people and work that attempt to use innovation to make social change. Langheier notes how the definition has progressively transcended non-profit organizations to also include for-profits and governmental efforts. Langheier is founder and CEO of Peer Health Exchange (http://www.peerhealthexchange.com ), a non-profit that trains college students to teach health education in public high schools. She graduated Yale University with a B.A. in History and serves on the board of directors of Dwight Hall at Yale, the center for public service and social justice.
