We Know How the Process Works

You have one opportunity to make a good first impression. Whether as a whistleblower or in civil litigation, we have seen the process from all sides and can make your voice heard.

Our Specialties


Whistleblowers bring the critical information Federal and State law enforcement need to uncover fraud in all its forms. We represent whistleblowers because we believe that without men and women committed to exposing wrongdoing, our justice system will suffer. It is a serious decision to become a whistleblower and, as former federal prosecutors, we know what the process will look like from start to finish and will make sure your voice is heard.
