Welcome to another edition of our Litigation Leaders series, featuring the litigation practice leaders at some of the biggest and most innovative law firms in the country. 

Meet Ronald Machen, the chair of the litigation/controversy department at Wilmer Cutler Pickering Hale and Dorr, who is based in Washington, D.C. Machen served as U.S. Attorney for the District of Columbia for more than five years during the Obama administration and his practice focuses on government enforcement actions, internal and congressional investigations, as well as civil business disputes. Upon taking on the role of litigation chair earlier this year, Machen succeeded Howard Shapiro, who led the department for 22 years, including during the integration of the litigation groups of Wilmer Cutler Pickering and Hale and Dorr after the firms’ 2004 merger.
