New Hampshire criminal defense attorneys Ted Lothstein and Richard Guerriero have more than 50 years of experience defending clients in criminal cases in all levels of the court system, from New Hampshire's District Courts, all the way up to the United States Supreme Court.

We regularly appear in District Courts throughout the State to defend misdemeanor criminal cases, DWI cases, and other motor vehicle offenses.

We have tried jury trials in most of the Superior Courts in this State, and in the United States District Court. We have won jury trials in many of NH's Superior Courts. We have successfully defended dozens of criminal appeals in the New Hampshire Supreme Court, and we have argued criminal cases in the First Circuit Court of Appeals in Boston and the United States Supreme Court.

We are admitted as defense attorneys in all NH courts:

  • NH Circuit / District Courts (these courts handle most misdemeanors)
  • NH Superior Courts for all counties (these courts handle most felonies as well as misdemeanor appeals)
  • NH Supreme Court (appeals of NH criminal cases)
  • United States District Court for NH (all NH federal crimes cases)
  • United States Court of Appeal for the First Circuit (appeals of NH federal criminal cases)
  • United States Supreme Court (discretionary review of both state and federal criminal cases)

Attorney Lothstein is also admitted to practice in Connecticut and New York. That means we can advise CT and NY citizens about collateral effects in their home state of a criminal charge in NH.

We are members of the following organizations and groups:

We have trained hundreds of lawyers in seminars sponsored by the following organizations:

New Trial, then Dismissal, for Therapist Wrongfully Accused
10/12/2018: In our most recent and perhaps our greatest victory, we won an appeal granting a new trial to a beloved and esteemed therapist wrongfully accused of sexual assault by a client. On October 12, 2018, the New Hampshire Supreme Court upheld a critical victory we had already won in the Superior Court - a victory that freed a therapist from prison who had been wrongfully accused of sexual assault by a client, and cleared his name. The Court held that the Superior Court was right to vacate the jury verdicts and sentences, and grant a new trial, for the therapist because juror bias infected the proceedings, resulting in an unfair trial. On October 17, 2018, the Merrimack County Attorney's Office issued a press release, announcing the State would not bring the case to trial again. Instead, the State dismissed the charges.
