Mayra de Aguiar

Mayra de Aguiar brings a practical, trial-focused approach to complex disputes, shaped by more than two decades of experience across law firm practice, in-house litigation leadership, and first-chair trial work. She is particularly skilled at distilling complex facts into clear trial narratives and developing focused trial strategies on compressed timelines. Her practice spans complex commercial litigation, class action defense, product liability, real estate, and contract disputes, as well as intellectual property, entertainment, and appellate litigation.

Mayra has served in both outside counsel and in-house litigation roles and has represented plaintiffs and defendants across a wide range of disputes. Her clients range from individuals and closely held businesses to Fortune 500 companies and global corporations across industries, including food and beverage, hospitality, consumer products, real estate, accounting and finance, technology, and entertainment.

At Willenken, Mayra’s recent work includes defending a leading home improvement company in a personal injury matter with significant claimed damages that resolved favorably on the eve of trial, and representing Harbor Freight, The Home Depot, McDonald’s, Procter & Gamble, and Spectrum Brands in complex litigation. She has also helped resolve fiduciary duty, fraud, negligence, breach of contract, and accounting malpractice claims for a high-profile fashion designer, as well as trade secret, non-solicitation, and fiduciary duty claims involving executives and employees of an electric vehicle start-up.

Before joining Willenken, Mayra served as in-house litigation counsel for The Wonderful Company—a global multibillion-dollar food and consumer products company—where she managed product liability, class actions, water rights, and employment matters. In that role, she helped defeat more than a dozen class actions filed across the United States alleging product contamination.

Mayra is active in several professional organizations, including the California Lawyers Association’s Litigation and Intellectual Property Law Sections, the Hispanic National Bar Association, the Los Angeles County Bar Association, and the Latina Lawyers Bar Association.

Mayra began her career at a prominent Los Angeles law firm, where she developed substantial trial and arbitration experience in commercial and entertainment disputes, including royalty matters involving high-profile entertainers. She later founded and operated her own firm, where she served as first-chair trial counsel in personal injury, medical malpractice, real estate, and disability discrimination matters. She earned her J.D. from the University of Chicago Law School.
