Munger, Tolles & Olson LLP

Munger, Tolles & Olson is an elite SoCal firm with offices in Los Angeles; San Francisco; and Washington, DC. The firm is best known for litigation, and through its highly selective recruiting process, it hires a high number of clerks. 

Cali Firm with Cornhusker Friends

Munger Tolles was founded in 1962 by seven partners, including Charles Munger and Edwin Leroy Tolles. Munger departed after three years, but this proved to work in the firm’s interests. A close friend of investor Warren Buffett, Munger became the Vice Chairman of Berkshire Hathaway, which in turn became a long-term Munger Tolles client. 

Tolles passed away in 2008, leaving Ronald L. Olson as the last name partner still in active practice at the firm. Olson, who joined in 1968, is also connected to Berkshire Hathaway (he’s a former director in the company) and served as Founding Chairman of the Board of Trustees of Southern California Public Radio. For many years, the Daily Journal (which happened to be owned by Charles Munger) has named Olson one of California’s most influential lawyers, acknowledging his work for clients such as Yahoo!, the J. Paul Getty Trust, Shell Oil, Michael Ovitz, and the late Paramount chair Brad Grey.

Winning on Pacific Time

Proving that the West Coast can be the best coast, Munger Tolles made headlines in 2008 when The American Lawyer placed it atop the magazine’s A-List. It was the first time the honor had gone to a firm outside New York but not the last: Munger Tolles has placed No. 1 on The American Lawyer A-List 11 times, most recently in 2025. Today, Munger Tolles attorneys work in 12 general practice areas with numerous subspecialities, and their strength in antitrust, securities, and white collar investigations and defense, as well as appellate work, is growing. Niche practices include bankruptcy. The firm’s clients include some of California’s largest companies in entertainment, energy, and retail; national corporations; large universities; leading Wall Street banks; foreign government agencies; and international corporations.

Own It

Munger Tolles is atypical in that it promotes an “ownership mentality” in its associates. In adherence to this culture, partners all weigh in on the pay of their fellow partners, and all attorneys have input into the recruiting process, review the firm’s financial books, and participate in all important firm decisions. A highly selective firm in terms of both hiring and its acceptance of cases, Munger Tolles has historically rewarded those who make it through the hiring gauntlet with an accelerated path to partner: The average associate can be considered for partnership between their sixth and ninth year at the firm. Although the firm keeps its roster lean, it prides itself on the breadth of talent within its doors, and clients who hire Munger Tolles may find themselves with lawyers who hold graduate degrees in history, literature, medicine, economics, or physics.
