Contact Information 312.589.6270

For more than 30 years, Kenneth A. Wexler’s focus has been on helping those whose rights have been denied, or who have been victims of the unscrupulous or fraudulent actions of others — usually by more powerful people and organizations. He devotes his practice to complex class action and commercial litigation and has been appointed to leadership positions in more than a dozen class actions throughout his career. These multi-million dollar cases have involved far-ranging subject matters, including brand name manufacturer suppression of competition from generic drugs, fraudulent and deceptive product overcharges, oppression of minority shareholders, discrimination and harassment, corporate waste and mismanagement, cost recovery for defective medical devices, false advertising, and government fraud.

Litigating class action antitrust cases against some of the largest pharmaceutical manufacturers in the world is truly where Ken has developed a niche. In 1997, Ken’s previous firm filed In re Synthroid Marketing Litigation, which was one of the first, if not the first, cases brought against a brand name pharmaceutical manufacturer for attempting to suppress generic competition, forcing consumers to pay more for their medication than they would in a competitive market. Since that first case, Ken has continued to be an active player in the pharmaceutical antitrust arena, having a key role in several major class actions and helping to recover more than $1 billion for consumers and third party payors affected by price manipulation and anticompetitive conduct. In 2014, Ken was part of a team that tried the first antitrust pay-for-delay generic class action since the Supreme Court’s Actavis decision.

Prior to founding Wexler Wallace in 2000, Ken was a partner at the firm formerly known as Much Shelist Freed Dennenberg Ament & Eiger, PC and a founding member of the firm Miller Faucher Cafferty and Wexler LLP. Ken received his J.D. from Georgetown University Law Center in 1980.

When not keeping a demanding case load and travel schedule, Ken spends his spare time with his family, volunteering with various not-for-profit and charitable organizations, and trying to perfect ascending vertical and oxer jumps at equestrian shows across the country.
