On this week's Protégé Podcast, we re-launch our series "What It Takes," where I interview dynamic, diverse leaders at the top of their professions. Our Guest Mentor on this episode is Gary Hall, partner and head of investment banking at Seibert Cisneros Shank. Gary reflects on his life and career journey from the Cabrini Green housing projects in Chicago to his White House Fellowship to chairing one of the financial industry's most important and prestigious boards. On the Rant/Rave/Review segment, I rave about Nike's approach to board diversity.
