In Chapter 3 of 9 in her 2011 Capture Your Flag interview with host Erik Michielsen, non-profit founder and executive Louise Davis Langheier shares what she has learned about leadership and organizational effectiveness as a board member at Yale University's Dwight Hall. Specifically, Dwight Hall's efforts teach her the value of clarity of mission, purpose, and goals. Langheier applies these lessons developing a more committed, focused approach at her non-profit, Peer Health Exchange. 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.
