Olivier Theard helps businesses manage environmental risks through a combination of regulatory counsel, transactional insight, and dispute resolution. His practice includes advising on compliance with air quality, hazardous waste, and consumer product laws, as well as representing clients in administrative hearings and environmental litigation. He is co-managing partner of the firm’s Los Angeles office.
Clients rely on Olivier’s extensive experience navigating enforcement actions and resolving associated penalties and claims. A former litigator with deep knowledge of environmental insurance, he brings a strong risk-management lens to M&A and other transactions involving contaminated properties.
Olivier represents parties responding to investigations of contaminated sites involving substances such as chlorinated solvents, petroleum products, and PFAS. He works closely with environmental agencies to reach practical, cost-effective solutions.
Regulatory advocacy is a key aspect of his practice. He prepares administrative petitions and appears before agencies such as the South Coast Air Quality Management District, the Department of Toxic Substances Control, and California’s regional water quality control boards, advising clients on their obligations and compliance strategies.
Proposition 65 compliance and litigation are another area of focus, including both product-related and environmental warnings. Olivier also handles administrative actions brought under the Clean Air Act, CERCLA, and related state and federal statutes.
Clients in sectors ranging from steel, semiconductors, and medical devices to coatings, restaurants, and pet care turn to him for environmental counsel tailored to their operations and risk profile.
In his free time, Olivier enjoys spending time with his family, watching and talking sports, and staying fit through calisthenics, weightlifting and tennis.
