Wow, it's a prestigious honor in itself to write this recommendation. John Brennan is the epitome of what everyone should except for a leader. Let me start off by saying that he is an extremely humble leader who serves solely for his subordinates and organization. He seeks only to improve the organization and the people, which is evident in his character and personality. People are drawn to him and are quick to serve alongside him because he’s loved by all. I can’t say enough about him because there are not enough words to describe him. John will serve any organization well, and everyone will benefit from his presence.
