September 11th marks an anniversary no one wishes there was a need to have. Like many of the most traumatic moments in American history, we remember vividly exactly where we were that day, the horrific images forever seered into our individual consciousness and the consciousness of the nation. For those of us who worked on Wall Street at that time, watching the collapse of the Twin Towers where many of our friends and colleagues worked, made the events of that day even more poignant.
