She encourages the phased use of discovery tools to streamline proceedings and reduce costs, ensuring fair and efficient proceedings. Her dedication to civil trial efficiency and background in business provides her with a strong foundation for handling a wide variety of disputes including those involving employment, intellectual property and trade secrets, insurance coverage and bad faith, securities litigation, construction defect, consumer fraud, personal injury, class actions, and contract and partnership issues.

Appointed to the Superior Court of San Mateo County in 2002, Judge Weiner quickly distinguished herself as a formidable presence on the bench, deeply committed to championing efficiency, ensuring equitable outcomes for all litigants, and modernizing the court system by revamping the civil division from a Master Calendar system to a single judge assignment system. Tasked with adjudicating some of the county’s most multifaceted and high-stakes cases, she demonstrated a profound understanding of both the technical intricacies and the human implications inherent in complex civil disputes. Her exceptional journey has been defined not only by her legal acumen but also by her ability to transform multifaceted legal issues into understandable, actionable judgments that resonate with litigants and attorneys alike.
Before her appointment to the bench, Judge Weiner built a career as an attorney in private practice, where she honed her litigation skills on a wide range of cases and gained invaluable trial experience. She later became a partner of her law firm and quickly established herself as a skilled litigator in civil cases. Her work there included high-profile litigation and significant jury trials, solidifying her reputation as a sharp legal mind and a tenacious advocate for her clients.
As she continues her work in arbitration and dispute resolution, Judge Weiner brings a wealth of knowledge, a reputation for fairness, and a legacy of dedication to justice. Her commitment to excellence, combined with her openness to innovation and sensitivity to the needs of litigants, make her an exceptional arbitrator and referee across a diverse spectrum of civil disputes.
