BIO

Margaret represents manufacturing and commercial clients in environmental, natural resource and litigation matters in Washington and California. She focuses her practice on regulatory compliance, including with California’s controversial “Proposition 65” chemical warning law, federal and state OSHA regulations and the U.S. Department of Homeland Security’s Chemical Facility Anti-Terrorism Standards (CFATS). She also represents clients in Superfund-type cleanup cases at legacy remediation sites, such as at harbors and airports, and at smaller sites.

Margaret began her career in 1992 at White & Case in Los Angeles as a commercial litigator where she focused on insurance recovery for environmental response costs. Prior to rejoining Riddell Williams, she practiced as a general practitioner with an emphasis on civil litigation. Margaret was born in France and lived many years in Paris, France. She is fluent in French.
