  • Amy C. Connolly

    I am writing to endorse Richard Samdperil. As a former prosecutor, I have had many cases against Attorney Samdperil. He is very intelligent and is a fierce competitor in the courtroom. He is well versed in New Hampshire case law and in the Rules of Evidence. His clients surely will benefit from his trial skills, knowledge of the law, and good reputation in the legal community.
