Ronald A. Valenzuela

Ronald Valenzuela has been practicing in California for nearly two decades, representing clients, including Fortune 100 companies, in the aerospace, energy, pharmaceutical, and consumer products industries.  He has counseled clients facing Prop 65 demands and litigation, and he possesses a broad range of knowledge and experience in the areas of law that form the necessary components of a comprehensive Prop 65 practice, including products liability, consumer class action, toxic tort, and environmental law.

Ronald Valenzuela is a partner in the firm's Insurance Recovery and Counseling practice. He represents policyholders in disputes of all kinds with insurers and has extensive experience in other complex litigation matters including product liability, mass tort, environmental and consumer cases.

Ronald’s insurance coverage practice ranges from large environmental and product claims to complex property and business interruption losses. He also handles disputes under director and officer, errors and omissions and fiduciary liability policies. In addition to litigating coverage claims throughout the country, Ronald advises clients on complex underwriting and risk management issues, including counseling on insurance policy terms and insurance policy audits. He also has significant experience in counseling biotechnology companies in product liability and insurance matters arising from clinical trials of investigational new drugs.

In addition to his insurance practice, Ronald also represents companies in a variety of other complex cases, including consumer class actions. He has defended consumer electronics manufacturers and distributors and financial companies, at both the trial and appellate level, against numerous class actions filed throughout the United States alleging violation of state unfair business practices acts, consumer fraud statutes, breach-of-warranty and Magnusson-Moss Warranty Act claims. He has also defended aerospace and defense contractors and property owners against claims brought under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Acting, for example, as second chair in a bifurcated trial in federal court, Ronald helped obtain a judgment on behalf of the parent of a shipyard operator exonerating his client of liability as an “owner” under CERCLA.

Clients he has worked with have included both Fortune 500 and smaller companies, such as Aerojet-General Corporation, Alpha Therapeutic, British Petroleum, Whittaker Corporation, Sony Electronics Inc., Microsoft, Philip Morris, the International Vaccine Institute, Countrywide Home Loans, BCI Coca-Cola Bottling Company of Los Angeles, MediciNova, Inc. and Adobe Systems Incorporated.
