Dan Alberstone co-manages Baron & Budd’s Los Angeles law office. He has more than 30 years of broad experience prosecuting complex litigation matters, including extensive jury trial experience. He specializes in consumer class action litigation in the areas of consumer protection and financial fraud.

Mr. Alberstone’s reputation for tenacious representation and zealous advocacy, as well as his proven track record, has led to his selection as lead trial counsel in numerous complex, high-stakes litigation cases, as well as his appointment as lead class counsel in a number of high-profile class action cases, including cases against large national banks and multinational corporations. Some of Mr. Alberstone’s notable consumer class action cases include Payne v. Bank of America, N.A., et al., involving manipulation of the LIBOR U.S. Dollar rate, Bias et al. v. Wells Fargo & Company, et al., concerning illegal mark-ups of default related fees, Ellis v. JP Morgan Chase and Stitt v. Citibank, concerning unlawful charging of unnecessary default fees, Waldrup v. Countrywide Financial Corporation, concerning illegal charging for fraudulent appraisals, Weiner v. Ocwen Financial Corporation, involving illegal assessment of default-related service fees that contained undisclosed mark-ups, and Ono v. Head Racquet Sports USA, concerning false advertising of Head tennis racquets.

Mr. Alberstone also represents governmental entities in enforcement of their consumer protection laws. He is currently representing the states of Hawai’i and New Mexico against Bristol-Myers Squibb and Sanofi for unfair and deceptive business practices in the marketing of the antiplatelet drug Plavix. According to the allegations in the complaints filed, these pharmaceutical companies failed to disclose to prescribing physicians and patients that Plavix has diminished or no effect on a significant portion of the patient population in these states and that those patients for whom Plavix would not work could have been identified through a simple genetic test.

The Los Angeles Daily Journal has recognized Mr. Alberstone for obtaining one of the top plaintiff’s verdicts in 2009. He has been repeatedly selected for inclusion on the Southern California Super Lawyers list since 2005 (Thomson Reuters) and served several years on the Board of Governors of the Association of Business Trial Lawyers.
