Andra B. Greene heads Irell & Manella LLP’s Class Action Defense practice group and previously served as managing partner of the firm's Newport Beach office.

A seasoned trial lawyer, Andra’s practice encompasses a wide range of complex business litigation, with an emphasis on class action defense and professional liability defense. Her extensive trial and appellate experience in state and federal courts also extends to commercial, wage and hour, employment, business torts, real estate, lender liability, executive compensation, environmental issues, securities litigation, insurance coverage, trade secrets, white collar criminal claims and intellectual property. She frequently represents other lawyers and major law firms when they need counsel.

Andra’s results for clients illustrate why she is sought after for the most sensitive and high-stakes matters. Some recent highlights include winning a bench trial in a partnership dispute, resolving high-profile consumer class actions for a well-known technology company, securing decertification and a dismissal with prejudice of a false advertising class action brought against a dietary supplement company, defeating high-profile whistleblower retaliation and discrimination claims against a professional sports team after a five-day arbitration and defeating a class action brought against a major sports venue by a putative class of former workers.

Andra’s victories on behalf of some of the country’s most recognized companies have led to such accolades as being named one of the “2019 Top Women Lawyers in California” by the Daily Journal. She was also recognized as the “2018 Orange County Bet-the-Company ‘Lawyer of the Year’” by Best Lawyers in America for her successful defense of cases including class actions. In 2016, Andra was named among the “Top 50 Women Lawyers” in the nation by the National Diversity Council. She was also honored as one of the “2014 Women Worth Watching” by the Diversity Journal.

Andra teaches an advanced course on class actions at UC Irvine School of Law.
