Product liability, mass tort and class action - defense: consumer products (including tobacco)

Operating from offices in Los Angeles, New York, Washington DC, and San Francisco, the consumer product liability and mass torts team at DLA Piper LLP (US) is known for defending high-profile clients in mass torts, class actions, and complex consumer litigation. Attorneys of the firm are praised by clients for their ‘high level of expertise & experience, and an absolute commitment to the assignment’, often handling precedent-setting cases for global companies such as Apple, Johnson & Johnson, Danone, and MGM across various sectors, including pharma, healthcare, media and entertainment, and food & drink manufacturing. The group’s expertise further extends to environmental matters such as PFAS litigation, microplastics claims, and sustainability issues, securing key motions to dismiss for clients like Danone and Starz Entertainment. Prominent attorneys in the group include Atlanta based Christopher Campbell, and LA based Angela Agrusa, co-chairs of the firm’s product liability & mass torts group, with Agrusa having notably defended over 50 putative class actions with potential exposure exceeding $100bn. Keara Gordon, a seasoned trial lawyer, has won precedent-setting motions to dismiss for clients including NYU and KLM Airlines, while Colleen Gulliver focuses on emerging issues like sustainability and environmental contamination, representing international pharmaceutical companies such as Pfizer. Both Gulliver and Gordon are based in New York. San Francisco based Isabelle Ord, co-chair of the global class action litigation practice, is recognized for her work in business disputes, fraud, and regulatory enforcement matters. Hildy Sastre joined the team in Miami in March 2026 from Shook, Hardy & Bacon LLP.
