Welcome to Grenier Law Group PLLC
GLG is a dynamic Washington, D.C. based personal injury/wrongful death civil litigation boutique firm with a nationwide practice, outstanding reputation, and an impeccable track record of success. With almost 50 years combined legal experience, our philosophy is simple – we advocate tenaciously and passionately to enforce the rights of our injured or deceased clients, and to bring about change by holding wrongdoers accountable – individuals, corporations and governments alike.
Whether it be litigating the only successful case arising out of the Columbine High School shootings in Colorado, securing an $11 million settlement package in the Virginia Tech Massacre cases, obtaining a record-setting $98 million wrongful death verdict against the District of Columbia, a record-setting $14 million wrongful death settlement in a bus collision case against WMATA, or a $26 million structured settlement on behalf of a victim of police misconduct in New Jersey, firm principal Peter Grenier and his team fight hard for each and every client. Most recently, in November of 2021, GLG won a $107 million personal injury jury verdict in Prince George’s County, Maryland Circuit Court. These stellar results do not come by chance or by luck – they are the culmination of countless hours of strategizing, researching, investigating and execution that go into every case that crosses our doorway.
