Campbell also spoke at orientation in 2009, as chronicled by a blog you can access here.
He has quite the story. After leaving active service in 2005, Campbell attended Harvard Business School, where he graduated with high distinction and was named a Baker Scholar for performing in the top 5% of his class. During his second year of the masters program, he was recalled to active service, and in 2008 he deployed to Afghanistan as a Captain supporting Special Operations Command, Central.
Campbell was awarded a Defense Meritorious Service Medal for exceptional service overseas. In May 2009, Random House published "Joker One," a memoir about his combat infantry leadership experiences. Random House is set to publish his second book, which centers on character-based servant-leadership, in March 2013.
