Lead Executive: Barry Salzberg, CEO
Salzberg became chief executive in 2007, 30 years after starting at the consulting firm. He is an advocate for higher-education and supports the efforts of College Summit, a non-profit organization that works in underprivileged areas to help high schools -- and the communities they serve--develop a culture in which going to college is the norm, not the exception. Recently, he lectured at Purdue University on the importance of ethics in an increasingly mobile work environment and the role of leadership in building a culture of ethics and trust.
