Shannon Royster

Shannon E. Royster joined the Los Angeles offices of Baron & Budd in 2022. She is a member of the firm’s Class Action Litigation Group and works on product liability litigation, automotive defect class actions and other complex litigation matters.

Prior to joining Baron & Budd, Ms. Royster spent several years focusing her litigation talents on advocating for consumers under California’s Proposition 65, ensuring that toxic chemicals are removed from the foods people eat and the products people use. “I feel strongly that my place in the law is to check corporate abuses of power. Company revenue should not come at the expense of human health and safety.” To that end, Ms. Royster oversaw a plethora of active consumer protection and toxic litigation cases, including complex civil actions concerning private enforcements of Proposition 65, in her work as a senior associate at a Beverly Hills law firm.

A Michigan native, Ms. Royster moved to Texas to attend Trinity University in San Antonio, where she received a Bachelor of Arts, majoring in political science and history. She then relocated to California to obtain her Juris Doctor from Southwestern Law School in Los Angeles. While in law school, Ms. Royster was on the Dean’s List, won a Witkin award for academic excellence, received a Blue Book award for her work on Southwestern’s Law Journal, and was awarded a public service distinction for having been an exemplary advocate who gave selflessly of her time and abilities to provide assistance to the Office of the Los Angeles County Counsel. She also served as an extern in the United States Attorney’s Office for the Central District of California and worked as both a research and teaching assistant for her Constitutional Law and Torts professors. Not long after her graduation from law school, Ms. Royster’s paper, Contracting for Blue Gold: An Examination of the Legal Designs Surrounding Private Water Delivery, was published by the Southwestern Journal of International Law (2017).

Ms. Royster’s love of the law began in high school, when she participated in the “We the People” competition sponsored by the Center for Civic Education, where she competed in the national finals and returned the following year as a student coach. It was then that Ms. Royster discovered she had a flare for government, civics and history, and an affinity for championing the rights of common citizens that continues to inspire her. She is a firm believer that Baron & Budd’s class action work levels the playing field against corporations that have no legal incentive to be mindful of the public interest. “Companies need to be held accountable for the unbridled harms they cause in the name of shareholder profits.”

When she is not pursuing corporations for their egregious disregard of public safety, Ms. Royster enjoys cooking, exploring southern California restaurants and caring for her rescue pup. She also takes great delight in her affection for niche perfumery.
