She is committed to obtaining justice for consumers and has recovered billions of dollars for her clients and the classes they represent.

Rosemary serves in leadership positions in a number of large-scale complex class action cases and multi-district litigation. In a highly competitive appointment process, the Honorable Charles R.

In 2022, Rosemary was appointed to serve as Plaintiffs’ Interim Co-Lead Counsel in the In re: Gerber Heavy Metals Baby Food Litigation, which involves allegations that Gerber marketed and sold baby foods containing dangerous levels of heavy metals such as lead and inorganic arsenic. In his order appointing Rosemary as Interim Co-Lead Counsel, Judge Michael S. Nachmanoff wrote that Rosemary has “significant experience and knowledge litigating class action cases involving food mislabeling consumer fraud.”

She has received numerous awards and honors for the quality of her legal work, including the Bay Area Legal Aid Guardian of Justice Award for her achievements in the law and her role in helping direct cy pres (remaining settlement) funds to promote equal access to the legal system. She has been recognized as a Northern California Super Lawyer since 2019, and was previously named a Rising Star by Super Lawyers Magazine.
