Peter Grenier has realized over


in verdicts and settlements for his clients

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. 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.
