Williams & Jensen

Williams & Jensen was co-founded in 1970 by J. D. Williams, one of the most respected tax and business lobbyists in Washington, and the late Robert Jensen, known for his antitrust, securities, and litigation experience. In many ways, the firm’s success continues the dual approach set at its beginning: highly effective government relations, grounded in technically proficient law.

Williams & Jensen has since grown to become one of the few leading independent law firms in Washington with a practice focused primarily on lobbying. On a daily basis, we help companies and organizations in the U.S. and around the world influence legislation and public policy process in Washington. The firm’s record of winning in Washington has attracted a clientele of leading companies, trade associations, and institutions, many relying on the firm’s services for more than three decade as one of the nation’s leading government affairs law firms.
