Wilmer Cutler Pickering Hale and Dorr LLP (known as WilmerHale) is an American "BigLaw" firm with offices across the United States, Europe and Asia. It was created in 2004, through the merger of the Boston-based firm, Hale and Dorr and the Washington-based firm Wilmer Cutler & Pickering; and employs more than 1,000 attorneys worldwide. WilmerHale ranked 2nd in the nation in American Lawyer's A-List of top BigLaw firms, and the firm is one of the most selective law firms in the United States for incoming associates. WilmerHale is known for its connections to the federal government; many of the firm's attorneys have experience in the Department of Justice, the Department of Defense, the Executive Office of the President, the Securities and Exchange Commission, and other federal agencies. Notably, former FBI Director Robert Mueller was partner at WilmerHale's Washington office before being hired as Special Counsel to the investigation into Russian interference in the U.S. presidential election. Other attorneys at WilmerHale include Seth Waxman, former Solicitor General of the United States; Ken Salazar, former United States Senator from Colorado and United States Secretary of the Interior; and Jamie Gorelick, former United States Deputy Attorney General. According to one study examining political donations by large white shoe firms, WilmerHale was ranked as the most liberal out of the top twenty most prestigious law firms in the nation.
Hale and Dorr was founded in Boston in 1918 by Richard Hale, Dudley Huntington Dorr, Frank Grinnell, Roger Swaim and John Maguire. Reginald Heber Smith, author of the seminal work Justice and the Poor and a pioneer in the American legal aid movement, joined the firm in 1919 and served as managing partner for thirty years. Hale and Dorr gained national recognition in 1954 when partner Joseph Welch, assisted by associate James St. Clair and John Kimball, Jr., represented the U.S. Army on a pro bono basis during the historic Army-McCarthy hearings. In 1974, James D. St. Clair represented President Richard Nixon before the Supreme Court of the United States in United States v. Nixon. In 1988, partner Paul Brountas chaired the presidential campaign of Massachusetts Governor Michael Dukakis, and in 1990, senior partner William Weld was elected governor. The firm has had a long and mutually very profitable relationship with nearby Harvard Law School, alma mater of more than a fifth of Wilmer Hale's current lawyers, and home of the Wilmer Hale Legal Services Center.
In 1988, the law firm established a subsidiary as a registered investment adviser. Initially known as Haldor Investment Advisors, L.P., and then Hale Dorr Wealth Advisers. In 2008 Hale Dorr Wealth Advisors became Silver Bridge.
Wilmer, Cutler & Pickering was founded in Washington in 1962 by former Cravath attorneys Lloyd Cutler and John Pickering, along with a senior lawyer, Richard H. Wilmer. Cutler, who later served as White House Counsel to Presidents Jimmy Carter and Bill Clinton, founded the Lawyers' Committee for Civil Rights Under Law in 1962, and served on its executive committee until 1987.
In the 1980s, Cutler led the founding of the Southern Africa Legal Services and Legal Education Project, to aid South African lawyers who fought to implement the rule of law during apartheid. From 1981 to 1993, partner C. Boyden Gray left the firm to serve as White House Counsel to Vice President and President George H. W. Bush. In 2003, partner Jamie Gorelick began serving as a member of the 9/11 Commission.
In 2010, the law firm relocated its administrative support base to a new campus in Dayton, Ohio as it sought to streamline internal business operations across its many offices. The office houses more than 200 employees from existing Wilmer Hale offices and new employees from the Dayton area. Individuals in the Business Services Center include administrative support staff, bringing together services such as finance, human resources, information technology services, operations, document review and management, and practice management, which will provide improved efficiencies for administrative teams and the firm, and reduce significant operational expenses.
WilmerHale has been consistently ranked as one of the most prestigious law firms in the United States. As such, WilmerHale is one of the most competitive law firms for incoming associates, who typically come from top-ranked law schools, graduate at or near the top of their class, and serve on law review or other journals. Many incoming associates at WilmerHale complete federal clerkships, either at U.S. district courts or the U.S. courts of appeals. 
In 2018 WilmerHale ranked 2nd in the popular "American Lawyer" "A-List" of the nation's twenty leading law firms based on revenue per lawyer, pro bono work, associate satisfaction, and diversity. It ranks as one of the "Best Law Firms to Work For," one of the law firms with the "Best Compensation Package," and one of the law firms with the "Best Culture."  The Washington Post ranked WilmerHale as the #4 top work place in DC and the #1 law firm based on associate satisfaction. The Washington Post noted that WilmerHale "received especially strong marks from its employees on career development for young lawyers." 
In the late 1980s, Hale and Dorr partner Jerome Facher represented Beatrice Foods in a suit by eight families from Woburn, Massachusetts who claimed that Beatrice, along with W.R. Grace, had polluted the town's water supply, resulting in an elevated number of leukemia cases and immune-system disorders. The case was memorialized in the book A Civil Action, by Jonathan Harr, and in a movie of the same name starring Robert Duvall as Facher and John Travolta as plaintiffs' lawyer Jan Schlichtmann. Upon further discovery, the EPA took the case on and W.R. Grace was successfully indicted for making false statements. Both W. R. Grace and Beatrice Foods paid a total $64.9M to clean up the contaminated sites in Woburn.
In the wake of news articles raising concerns about transactions between Enron and its CFO, Andy Fastow, lawyers from Wilmer Cutler & Pickering represented a special investigative committee of Enron's board of directors in an internal investigation into those transactions. The resulting report, known as the "Powers Report," laid out the facts that have been the predicate for much of the public discussion of Enron since that time.
Similarly, after WorldCom's announcement that it would have to restate financial statements, the firm represented a special investigative committee of WorldCom's board of directors in performing an internal investigation into the accounting irregularities. The investigation resulted in a widely covered written report that detailed a variety of accounting issues as well as the role of management and the board of directors.
In 1986, Wilmer, Cutler & Pickering represented corporate raider Ivan Boesky in high-profile Department of Justice and SEC proceedings, as well as multiple class actions based on his participation in insider trading violations.
Wilmer, Cutler & Pickering represented Swiss banks accused of profiting from the Holocaust in their settlement negotiations with plaintiffs. The firm also represented Siemens AG, Krupp AG, and other German companies accused of exploiting forced laborers during the Nazi era.
Wilmer Hale was hired to represent PepsiCo in the SEC investigation related to the departure of PepsiCo general counsel Maura Smith. In the course of this representation, a Wilmer Hale attorney inadvertently e-mailed a confidential legal memorandum to a Wall Street Journal reporter as part of an internal communication to other attorneys working on the matter, which made several details of the investigation public.
Both Hale and Dorr and Wilmer, Cutler & Pickering have a long history of involvement in pro bono work. Wilmer Hale has ranked at or near the top of The American Lawyer pro bono ranking since the merger. In recent years, the firm has been involved in several high-profile cases.
A team of Wilmer Hale attorneys represents the "Algerian Six", a group of men who fell under suspicion of planning to attack the US embassy in Bosnia and who are now held in the Guantanamo Bay detainment camp.
In 2006, attorney Melissa Hoffer, then part of the team with WilmerHale, delivered a speech in Caen, France, critical of U.S. detainee policy. Other Wilmer Hale lawyers participating in the case include Stephen Oleskey, and Rob Kirsch.
In January 2007, Cully Stimson, deputy assistant secretary of defense for detainee affairs, criticized WilmerHale and other major law firms for representing "the very terrorists who hit their bottom line back in 2001," and questioned whether such work was really being done pro bono or might actually receive funding from shadowy sources. In a Wall Street Journal editorial criticizing Stimson, Harvard Law School professor (and former United States Solicitor General under President Reagan) Charles Fried wrote:
It is no surprise that firms like WilmerHale (which represents both Big Pharma and Tobacco Free Kids), Covington & Burling (which represents both Big Tobacco and Guantanamo detainees), and the other firms on Mr. Stimson's hit list, are among the most sought-after by law school graduates, and retain the loyalty and enthusiasm of their partners. They offer their lawyers the profession at its best, and help assure that the rule of law is not just a slogan but a satisfying way of life.
