We have represented hundreds of clients charged with driving under the influence, driving while intoxicated, impaired driving, and other alcohol or drug related motor vehicle offenses. If you have been charged with driving while intoxicated or under the influence, call 603-775-7570 to speak to one of our experienced attorneys.

Defending a client charged with DWI or DUI requires skill, knowledge, and experience. For over 20 years, we have been representing clients who have been accused of Driving While Intoxicated. We have helped thousands of clients negotiate the judicial system and the DMV.

Attorneys Richard Samdperil and Joseph Welsh have special training in Field Sobriety Testing and Intoxilyzer breath testing – the same tests that New Hampshire law enforcement uses to determine alcohol impairment and whether someone is under the influence of drugs, alcohol, or a combination of the two.

In DWI cases, timing is very important.  Arraignments (the first court appearance) is typically scheduled within 14 days of arrest.  And, if you blow over the legal limit or refuse to take a breath test, you have only 30 days to request a special hearing or you will automatically lose your driver’s license for at least 6 months.  We represent every DWI client in court and at the DMV, because coordinated representation in both the judicial process and the administrative hearing process is essential to obtaining the best possible outcome.

We understand how devastating a drunk driving charge can be, and how quickly these charges can impact a person’s family and career.  We work with our clients to explore the best options, defend their legal rights, and build the strongest possible defense.

Driving While Intoxicated (DWI) or Driving Under the Influence of drugs or alcohol (DUI) is a complex and significant charge. The police have extensive training in gathering evidence and prosecuting these cases, and a conviction has longterm and serious consequences.  We offer over 20 years of DWI litigation and trial experience, and have tried cases in almost every court in southern New Hampshire.

We carefully review every aspect of your case, from the reason you were stopped, to the validity of the field sobriety tests and results.  We handle DWI cases in all New Hampshire state courts, and regularly represent clients charged with DUI or DWI in the Circuit Courts in Brentwood, Candia, Derry, Dover, Plaistow, Portsmouth, Rochester, Salem and Seabrook.  Whether the case is prosecuted by the New Hampshire State Police or the local police department, we will guide you through the process and fight for the best possible outcome.
