Keil Mueller is a resolute and tireless advocate for his clients’ interests.
With over 15 years of litigation experience, Keil has regularly represented government entities, investors, consumers, businesses and other Plaintiffs in a wide variety of complex legal matters and class actions. His practice focuses on issues related to securities and financial fraud, the environment, consumer class actions, and partner and shareholder disputes among others. Keil’s thoughtful but tenacious pursuit of his clients’ claims has contributed to significant courtroom victories and favorable settlements. He has successfully represented clients in matters of corporate malfeasance, taking on big companies such as AIG, Oppenheimer, FedEx Ground, JP Morgan Chase, and Bank of New York Mellon, just to name a few.
Currently, Keil is a key member of teams prosecuting claims on behalf of the State of Maryland, the State of Delaware, and the City of Seattle against multinational chemical manufacturer, Monsanto, and seeking to hold the corporate giant responsible for environmental contamination and other harms caused by Monsanto’s sale and marketing of PCBs. Prior to joining Keller Rohrback, Keil also was a member of the team that represented the State of Oregon in similar claims against Monsanto, which Monsanto recently agreed to settle for $698 million, the largest environmental settlement in Oregon’s history.
In addition to advocating for his clients, Keil serves as a board member of the Campaign for Equal Justice and of the Oregon Lawyer Chapter of the American Constitution Society.
