Client Reviews
From the very first phone call with Tenn And Tenn, until the day my motorcycle accident case was settled, John and his terrific staff have been nothing short of amazing. The motorcycle accident lawyers at Tenn And Tenn are the best injury lawyers in New Hampshire. They updated me frequently on the status of my case, answered all my question and made me feel comfortable every step of the way. Mark P.
Jim Tenn is unlike any other lawyer you will meet. I first met Jim when my life was falling apart... Jim worked tirelessly for me, and on behalf of my two children to get the best possible results in a case fraught with difficulties and unnecessary complications. At what is undoubtedly the lowest point in your life, you need someone who has your back and protects your interests while you're frantically trying to keep things together. Jim Tenn is the man to hire. H.E.
Jim is an excellent and very thorough divorce attorney who examined every possible aspect of my case. I found his knowledge of the law and his courtroom capabilities to be outstanding. He deserves the reputation that he has as one of New Hampshire Super Lawyers. It is very comforting having an attorney whom you can trust during difficult personal issues. Jim Tenn is that lawyer. Thank you for all your help Jim. Anne
