Each Thursday on Global Activism, we hear about an individual who’s decided to work to make the world a better place. Matt Rooney is a partner at the Chicago law firm Mayer Brown. He oversees the firm’s pro bono projects around the world. Rooney recently returned from Iraq, where he trained a group of trial lawyers via a program developed by Heartland Alliance International, a Chicago organization that provides a range of services for vulnerable Iraqis.
