David practices in the firm’s nationally recognized Complex Litigation Group where he represents retirement plans, institutional investors, ESOPs, and individuals in federal and state courts across the country. David has experience in all phases of litigation, including trial and appeal, and focuses on cases involving breaches of fiduciary duty under ERISA, securities violations, investment mismanagement, and consumer protection violations. He has made substantial contributions to several multimillion dollar recoveries against some of the largest corporations in the country.

David was also part of the trial team that objected to a proposed $8.5 billion settlement brought by the Bank of New York Mellon in an effort to resolve Bank of America’s liability arising out of Countrywide’s issuance of mortgage-backed securities. The arguments raised by Keller Rohrback in an eight week trial in New York Supreme Court were the only objections sustained by the Court.

David also recently represented Super Bowl 49 ticket holders who purchased but did not receive their tickets as promised from various ticket brokers who engaged in short-selling, including filing the first class action arising out of this widespread and deceptive practice.

Prior to joining the firm, David completed a two year clerkship for the Honorable Ricardo S. Martinez, U.S. District Judge in the Western District of Washington.

David is past President of the Korean American Bar Association of Washington, and a 2014 Fellow of the Washington Leadership Institute.
