David is a partner in the firm’s nationally recognized Complex Litigation Group, where he represents plaintiffs in federal and state courts across the country in a wide variety of cases involving corporate wrongdoing. He has helped his clients—including government entities, retirement plans, individuals, and institutional investors—obtain several multimillion dollar recoveries against some of the largest corporations in the country.

David has significant experience in all phases of litigation, including trial, at both federal and state court. He was a lead trial attorney in a 14-week bench trial in the Northern District of Illinois involving breach of fiduciary duty claims on behalf of an employee stock ownership plan that resulted in a settlement after judgment and prior to resolution of an appeal. He was also part of the trial team representing three Federal Home Loan Banks that successfully objected to a proposed $8.5 billion settlement submitted by the Bank of America in New York Supreme Court arising out of its purchase of mortgage-backed securities from Countrywide.

David also represented thousands of Super Bowl ticket holders against various ticket brokers engaged in short-selling, including filing the first class action arising out of this widespread and deceptive practice.

Most recently, David has been appointed as a special deputy prosecuting attorney by numerous government entities as outside counsel in litigation against manufacturers, distributors, and dispensers of prescription opioids. David is one of the lead attorneys handling the firm’s opioid cases, and represents counties, cities, and Native American Tribes in Washington, Arizona, California, Colorado, Idaho, and New York in the national opioid litigation pending in the Northern District of Ohio.

Prior to joining the firm, David clerked for the Honorable Ricardo S. Martinez, Chief U.S. District Judge in the Western District of Washington. David is also past President of the Korean American Bar Association of Washington, and a Fellow of the Washington Leadership Institute.
