Mayer, Brown, Rowe & Maw is racing to build its global trade practice, doubling the number of attorneys in the group to 30 since late 2004 and pulling many of the new professionals from top government positions.

Over the past 18 months, the group has attracted new lawyers from the government, such as James Jochum, and new clients, such as Target Corp., said Peter Scher, who heads the practice for the firm. Jochum served as assistant secretary of commerce for import administration in the Bush administration from 2001 to 2005.
