About me

For 30 years I have focused my practice on criminal defense and the ethical responsibilities of criminal defense attorneys.  Our firm has an office in Keene, NH, where I am based, and we have an office in Concord, NH, where my partner, Ted Lothstein, is based.  While I handle many cases in Cheshire and Sullivan counties, I represent citizens throughout New Hampshire in state and federal court.  The Keene Office is just one block from both 8th Circuit Court -  Keene Division and Cheshire County Superior Court.

  • Donna J. Brown

    I have known Richard for most of the 20+ years that he has practiced in NH and I have seen his work in and out of the courtroom. He is hardworking, dedicated and almost always the smartest lawyer in the room.
