Client Reviews
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
