You could say Bill George hasn’t had a job since he retired as CEO of Medtronic in 2001 after leading the company for a decade. But he has never been busier. He’s a senior fellow at Harvard Business School, where he’s taught leadership since 2004, and serves on several boards, including the Mayo Clinic board of trustees. Yet he’s best known for his popular True North books, which have struck a chord with business readers who want to forge their own path. In the process George has become a nationally recognized expert, speaker and guru on the defining qualities of great leaders.
