In 2018, “The Customer Value Gap: Re-Calculating Route” highlighted the need and opportunity for the financial services industry to deliver new sources of value to its clients.

Aaron joined Oliver Wyman in 2001, became a partner in 2006, and served as the New York Office Head between 2007 and 2009.
