His book, "stewardship," is about lessons learned from the lost culture of wall street and details what happens when firms place their own self interest ahead of their clients.
Taft believes this is a result of those firms losing sight of their stewardship values.
"One of the causes of the financial crisis of 2008 and 2009, which none of us wants to have to go through again, was the fact that our industry lost touch with its basic mission, purpose and responsibility: which is to put client interest first and to help clients manage their financial affairs better than they could on their own," Taft said.
He recognizes the fact that changes still need to happen.
"It all starts at the top which is leadership, and people like me - CEOs of major financial institutions - have to tell our employees what our core purpose is: which is to serve clients. But it goes beyond that 'how do you get managers of major institutions to behave differently."
All proceeds from his book will be given to charity. For more information please visit www.johngtaft.com.
