Moore & Bruce, LLP was formed in 1993 by attorneys that had practiced together in the Washington, D.C. office of a mid-size New York law firm. There they comprised portions of the tax and international practice groups.

The founders of the Firm were joined by other attorneys, most of whom they had practiced with at one time or another in the past. Over time, other attorneys joined the Firm. One attorney, who practices U.S. and Chinese intellectual property law, left to join the U.S. Government. Another attorney left to join the U.S. Internal Revenue Service and subsequently returned.

The Firm was originally located in the Army and Navy Club building on Farragut Square in Washington, D.C.

In 1998, the Firm moved to the Adams-Mason House (c. 1810) in Georgetown, the historic part of Washington, D.C.

In 2003, as the offices of Charles M. Bruce, consultant in overseas law, offices were opened in Mayfair, London.

The Firm maintains representative offices in Wilmington, Delaware and Zurich.
