Diana Maier

Diana is the firm’s founder and a recognized expert in both employment and privacy law. She is certified by the International Association of Privacy Professionals in both European Union and U.S. Data Privacy. She conducts workplace trainings, including sexual harassment, diversity, and data security trainings. Diana also performs workplace investigations in Spanish and English, advises business owners on issues that arise in the workplace, and defends employers facing litigation.
Diana enjoys an outstanding reputation in both the legal and non-legal communities as an effective advocate and strategist due to her unique background. Before attending Stanford Law School, Diana worked as a lobbyist and foreign policy adviser on Capitol Hill. There, Diana learned about the legal process at its inception, the legislation drafting stage. As a foreign policy aide to Congressman Henry Waxman (D-CA), and as a legislative aide and lobbyist at the American-Israel Public Affairs Committee, Diana learned the value of great customer service and the art of speaking about the law to constituents in plain terms instead of legalese.
After law school, Diana became a public defender. She was lauded for her trial successes, which were exceptionally above county acquittal rates in both felony and misdemeanor court. To this day, Diana’s ease in the courtroom when stakes are high allows her to feel confident about trying a case when an effective compromise can’t be reached. Diana is also recognized for her ability to achieve great results with a limited budget.  
Diana’s passion is helping other lawyers find meaning in their work by practicing mindful lawyering and carrying their deeply held personal values to their professional life. To this end, she, her staff, and an incredible team of volunteer lawyers created a hugely successful Joy in the Law conference in September 2016.

Diana serves on the Strategy Council for OneJustice, a groundbreaking legal non-profit, teaches spinning classes, and enjoys running around Marin with son and daughter and incredibly tolerant husband, Ethan.
