Kimberly Branscome is a trial lawyer with a particular emphasis in mass tort and products liability litigation. She has served as trial counsel in a number of high-profile cases, including In re Oil Spill by the Oil Rig “Deepwater Horizon” in the Gulf of Mexico on April 20, 2010. Her experience includes product and professional liability, environmental and toxic tort, and securities matters.

Kimberly currently serves as one of Johnson & Johnson’s lead trial counsel in product liability litigation associated with Johnson’s Baby Powder. In December 2019, Kimberly achieved a victory for Johnson & Johnson by winning a hard-fought 10-week jury trial in Los Angeles in which the plaintiff alleged that the company’s baby powder contained asbestos and caused her terminal cancer. This win followed her complete defense verdict on behalf of Johnson & Johnson in Allen v. Brenntag North America Inc. in November 2018, where the plaintiff sought nearly $40 million in compensatory damages as well as punitive damages to be determined at trial. Law360 cited the case as one of the “Top Product Liability cases of 2018,” and the Daily Journal has selected both of her cases as one of its “Top Defense Verdicts” in 2018 and 2019.

Kimberly’s representation of GM in its ignition switch litigation has been lauded by Law360 in “GM Driver Virtually Unharmed By Icy Wreck, Expert Claims” and “GM Passenger Grapples With Scant Injury Records At Trial.” Kimberly served as trial counsel for GM in the second federal bellwether trial, Barthelemy Spain v. GM, and the first state bellwether trial, Stevens v. GM. Each trial resulted in a defense verdict for GM.

In 2019, Kimberly was named among the Los Angeles Business Journal’s “Top Litigators & Trial Lawyers,” and “Most Influential Women Lawyers.” She was also included in the Daily Journal’s 2019 list of “Top Women Lawyers,” and “Top 100 Lawyers in California.” Kimberly has been recognized in The Legal 500 United States for Product Liability, Mass Tort and Class Action: Toxic Tort - Defense in 2018–2019 and for Product Liability, Mass Tort and Class Action: Consumer Products in 2019. In 2017, Kimberly was named to Law360’s “Rising Stars” list for her trial work and was recognized by Southern California Super Lawyers as a “Rising Star” from 2013 to 2019 for class action and mass torts.
