Koren Bell is a partner at Larson O’Brien in Los Angeles.  She is an experienced trial and appellate lawyer with a record of success litigating high-stakes cases in courtrooms around the country.   Ms. Bell has handled complex white-collar criminal matters, including as Counsel of Record in the U.S. Supreme Court, and civil matters, including as trial counsel in highly-publicized cases in state and federal court.  She has represented both plaintiffs and defendants—including Fortune 500 companies, diplomats, and high-net-worth individuals—in all types of cases across a range of industries.  She is bilingual in Spanish and regularly represents Spanish-speaking clients. 

Before entering private practice, Ms. Bell spent over eight years at the Office of the Federal Public Defender in Los Angeles.  As a Supervising Trial Deputy in the largest office in the federal defender system, she helped oversee trial litigation, developed district-wide challenges to prosecutions, and defended clients in some of the Office’s most difficult federal criminal trial matters and appeals—including cases involving alleged cross-border criminal activity, each of the federal fraud statutes, bribery, public corruption, and capital murder.  

After graduating from Yale Law School, Ms. Bell began her career as a law clerk to the Honorable Stephen Reinhardt on the Ninth Circuit Court of Appeals. 

She is active in the community as a member of the Board of the Los Angeles Chapter of the Federal Bar Association, the Executive Committee of the Los Angeles County Bar Association, and the Mexican American Bar Association, as well as the WWCDA-LA.
