About Accredited Investigative Service

The private investigators at Accredited Investigative Service in Lebanon, Tennessee, are dedicated, first and foremost, to our clients, many of whom are criminal attorneys. However, we always act as an objective third party, never forming opinions or drawing conclusions. Our job is to gather unbiased factual data in a legal, thorough, and efficient manner, and then relay that data to our clients.

We have been in business since 2001, and our team has more than a century of combined investigative experience. They have diverse backgrounds in the criminal justice system, deep knowledge of federal and state laws, are bilingual English and Spanish speakers, and always answer their phones.
