From one practice group to another, from one generation to the next, there is something unique in the halls at Gibson Dunn: a seamless commitment to excellence that has continued for over a century by an elite group of lawyers who come to serve their clients selflessly and to achieve results. This is our story. In May 1872, a tall, 34 year-old, red-bearded lawyer stepped down from the stage-coach at the Plaza of Los Angeles. Corporate attorney John Bicknell had his sights on building a law practice. What greeted him at the stage was a humble little pueblo with dusty unpaved street, no industry and scant business. He saw a pueblo of narrow streets and alleys between decrepit adobe buildings roofed with "brea" from tar pits west of the city. Bicknell, who had summed up his philosophy this way when counseling a younger lawyer, "The safe way is to select a business that you will be satisfied to follow and build up a business of your own." He began to follow his own advice. By the 1880s, he had attracted one of the region's most important clients, the Southern Pacific Railroad. It took time to select a quality partner. But in 1890, Bicknell, a Republican, teamed with Walter Trask, a Democratic litigator, thus launching the unbroken chain of partnership that today is Gibson, Dunn & Crutcher. Also launched was a set of unique firm attributes. Those included selecting only quality lawyers; balancing ideas across the political spectrum; and providing powerful resources in both transactional and litigation-related legal services. More than a century later, these attributes still define today's Gibson Dunn. In 1897 Judge James Gibson joined the firm, thus instituting another Gibson Dunn tradition - hiring lawyers who make an impact in their communities. In 1903, in a move that created the largest firm in Los Angeles, Bicknell, Trask and Gibson merged their practice with that of former Los Angeles City Attorney William Dunn and former Assistant City Attorney Albert Crutcher. Carried out at the behest of a client in order to create a "full-service" firm, the combination was called an "experiment" in the local press. It has worked ever since. Nearly 100 years later, the press recently dubbed the firm "The Rescue Squad" for its response and service to clients in legal need. Another article remarked that it remains easier to get into the CIA than to become a lawyer at Gibson Dunn. The firm grew as the region grew, into both Northern and Southern California, and both nationally and internationally. By the 1970s, Gibson Dunn had offices in London and Paris. Shortly thereafter, the firm took the bold step of launching its practice in the nation's capital and New York. Since 2000, the firm has further expanded in Europe, South America, the Middle East and Asia. As John Bicknell might say, the firm has "built up a business", based on those attributes of quality, balance and impact and on an unrelenting mission of achieving success for clients - a mission shared today by approximately 1000 lawyers worldwide.

In every representation, their 200 lawyers are expected to make a difference in developing and implementing strategies to obtain the best results for the client. In a survey conducted by The American Lawyer, clients said they called on MTO in “precedent-setting cases that require a creative mind.” Where resources are needed, the survey noted that we are able to deploy an “army of trial lawyers capable of waging war.” MTO is involved in some of the most high-profile legal cases in the country and count among their clients Bank of America, Transocean, Edison International, Verizon, Rambus, Oaktree Capital Management, KB Home, LG Display, Yucaipa Cos. and Berkshire Hathaway.

Many of MTO's litigators honed their courtroom skills while serving as assistant U.S. attorneys and a number of our lawyers have advanced degrees in relevant subject matter areas, including physics, engineering and medicine. MTO is proud to count among their lawyers one of the top 19 trial lawyers in the country as identified by Chambers USA, as well as one of the Daily Journal's “Ten Top Lawyers of the Decade.” MTO has been consistently ranked on The American Lawyer's A-List since its inception in 2004, including four years in the top spot. This annual ranking of the nation's elite law firms ranks on the basis of financial strength, diversity, pro bono work and attorney satisfaction. MTO believes their core values and one-to-one approach are responsible for their success in these four areas, as well as in delivering consistent results to their clients.
