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.
