Daniel Henry

As other financial firms capsized amid the market meltdown, Henry helped American Express successfully navigate the crisis. And this year, he was recruited to join the board of Groupon to provide accounting expertise after the coupon company had to restate its 2011 financial results.

David Herzog

James Sawyer
