Mark Holscher is a partner in the Firm's Los Angeles offices and is a member of the Commercial Litigation Practice Group. In the last five years, Mark has obtained plaintiffs verdicts and settlements of over $1.4 billion, with multiple nine figure recoveries. Mark has also successfully defended clients against multiple claims in excess of a billion dollars. Mark’s background as a former Assistant United States Attorney coupled with his successful civil trial record has established him as a “go to” lawyer for companies and individuals facing significant litigation. Opposing counsel have described him as “bright and extremely talented” and his colleagues refer to him as an “extraordinary trial lawyer.” Mark is recognized as one of the few lawyers in the country who have obtained multiple dismissals of federal criminal matters post indictment, notably, four times in multiple districts. He regularly makes pre-indictment presentations that have convinced the Department of Justice not to bring charges.

As a nationally-recognized trial attorney, Mark is a Fellow in the American College of Trial Lawyers and the International Academy of Trial Lawyers. Mark’s achievements have been profiled in The Wall Street Journal, Bloomberg and the Los Angeles Times, as well as such prominent legal publications as the National Law Journal and The American Lawyer. Since 2008, Mark has been selected every year as one of the Top 100 Lawyers in California by the Daily Journal. In 2010, Mark won a $52 million jury verdict that was among the Top 100 verdicts that year, as reported by the National Law Journal and the Daily Journal. Mark has also been selected as one of Hollywood’s “Top 100 Power Lawyers.” He is consistently profiled as a leading trial lawyer in Chambers USA, Best Lawyers®, and the International Who’s Who of Business Crime Lawyers. In addition, from 2018–2022 Benchmark Litigation recognized Mark as a “Local Litigation Star,” and The Legal 500 U.S. has lauded Mark as being “among the top litigators in the country.”

Mark has acted as lead trial and appellate counsel to blue chip companies and their executives in a wide variety of securities related cases ranging from alleged individual and corporate securities law violations, merger and acquisition and hostile takeover litigation, and fraud and breach of fiduciary duty claims.

In 2013, Mark was selected for the second time for a California LawyerAttorney of the Year” award for his pro bono representation of a group of parents and the national education movement, when a California court became the first in the U.S. to verify a “parent trigger” petition to authorize parents to take control of an underperforming school in Southern California. Mark also received a California Lawyer “Attorney of the Year” award in 2000 for his successful defense of Los Alamos Nuclear Scientist Wen Ho Lee against espionage charges.
