Meet William Markham, a distinguished trial attorney situated in San Diego. His expertise lies in handling complex commercial disputes, particularly in the realm of antitrust law, across various parts of California. Holding a law degree from Harvard Law School, which he earned in 1987, he demonstrated his legal prowess by passing the California Bar Examination on his initial attempt. Mr. Markham embarked on his legal career as a litigator within the antitrust division of a global firm, Coudert Bros. (now defunct), stationed in its San Francisco branch.

In 1990, he ventured into an independent practice, driven by his eagerness to engage in courtroom trials early in his professional journey. This decision led him to handle numerous minor commercial and real estate conflicts, allowing him to master the tried-and-true approach of trial preparation and in-person court proceedings. As time progressed, he tackled more substantial cases and achieved favorable outcomes in fiercely contested business disputes. In 2001, he relocated his practice to San Diego, where he has since been operating while extending his legal services to various parts of California and occasionally beyond national borders.

From 2006 onward, Mr. Markham’s focus predominantly shifted towards antitrust matters and intricate commercial disputes of diverse nature. He emerged as a lead attorney in several high-profile national antitrust litigations and additionally served as an antitrust consultant for prominent global entities, including the largest LED product manufacturer worldwide, a global automobile manufacturer, and a top producer of pulse oximetry equipment. In courtrooms, he secured victories in the form of jury verdicts, bench trials, and pivotal appellate wins. Notably, he achieved two notable reversals on appeal, one notably in 2019 within the Ninth Circuit, concerning a significant antitrust case.

Beyond his courtroom feats, Mr. Markham is an accomplished author, penning a series of acclaimed articles covering antitrust law, trial procedures, and various other legal subjects. These writings can be accessed on his website at www.markhamlawfirm.com.law-articles. His expertise has also been sought by national and regional media outlets, including The New York Times, Bloomberg TV, KNSD, Voice of San Diego, and Univision, where he frequently contributes commentary on diverse legal matters. Mr. Markham’s commitment to the legal community extends to his role in the standards-setting committee of the San Diego County Lawyer Referral Association, where he played a pivotal part in drafting new standards for different attorney panels.

Mr. Markham’s passion lies in the courtroom, where he relishes the art of trying cases. He approaches each case with the premise that thorough trial preparation from the outset can lead to optimal outcomes. While he endeavors to achieve amicable settlements whenever possible, his involvement in a case signifies his readiness to take it to trial. Limiting his caseload to a select few at a time, he ensures that every matter receives the attention it deserves.
