    Experienced & Dependable Case Support
    Nason Investigations specializes in helping you deliver the best possible case support for your client in criminal or civil court. We spend the time doing the legwork that you need done but don’t have the time to do. The services Nason Investigations offers can uncover evidence that benefits your client or reveals errors made by law enforcement that can help you gain the upper hand during trial.

    Since its inception, Nason Investigations has been a member of the New Hampshire League of Investigators. The NHLI is the only professional investigator association in the State of New Hampshire and its members are guided by the highest standards of the profession. Membership in the NHLI benefits our clients by allowing us to seek immediate assistance if needed by other trained and professional investigators. Although some members of the NHLI may be smaller organizations, additional resources are only a phone call away.

    Criminal Court Cases
    The owner of Nason Investigations, Seldon (Don) Nason, has spent 20 years in law enforcement as a police officer, trainer, EMT-I, sergeant and police chief. With 12 years of criminal prosecution experience, his ability to understand the New Hampshire criminal court process is an important asset available to you in preparing your defense cases. A unique service Nason Investigations offers is reviewing police reports and evidence gathered against your client to analyze strong and weak points to focus on for further investigation and at trial.

    Civil Litigation
    With years of experience in the police and EMS fields, Nason Investigations can help your civil court cases by conducting interviews and gathering evidence that might make the difference between winning and losing a client’s case. Many times the evidence we uncover can persuade the other side to settle out of court, saving you and your client time and money and needless court system involvement. Most importantly, the work we do enables you to focus on the more important aspects of your cases.

    Background and Surveillance
    Nason Investigations has the experience and training to legally and effectively conduct background checks for witness preparation and pre-employment reasons. We also specialize in undercover surveillance with digital photography and video evidence support for divorce, worker’s compensation, insurance fraud and loss prevention purposes. We are trustworthy and reliable and get you the results you need to increase your success.
