One private detective agency. Every kind of question.
Most people who call us don't know the name of the service they need. They know something is wrong — a partner's story doesn't add up, a witness has vanished, money is leaving a business, a custody order is being ignored. Pinnacle's job is to turn that into a plan, put a private eye on it, and hand you documented facts you can act on.
Questions about the people closest to you, answered quietly and with proof.
Independent fact-finding for attorneys and self-represented parties across Tennessee.
Quiet verification for Tennessee employers, insurers and owners before a problem becomes a lawsuit.

A Delator Group company
Pinnacle operates as a division of Delator Group, Tennessee's corporately structured private detective agency and process serving corporation. That means chapter-officer review on every file, shared records and equipment, and a field network that already covers all 95 counties — no subcontracting, no hand-offs to strangers.
Questions about hiring a private detective in Nashville, Tennessee
A private eye is the individual doing the fieldwork. A private detective agency is the licensed business that employs, supervises and stands behind that work. Pinnacle is a licensed Tennessee private detective agency, so every private eye we send out works under agency licensure, agency insurance and a formal chain of review — you are never dealing with a lone freelancer.
Yes. Private detective work is a regulated, licensed profession in Tennessee. What matters is that the agency you hire is properly licensed and that its methods stay inside state and federal law — no illegal recording, no trespass, no unlawful tracking. Pinnacle operates entirely within that framework, which is also what keeps our findings usable in court.
It depends on the type of case, the hours of fieldwork and the records work involved. A short activity check costs far less than a multi-day surveillance operation. We give you a realistic estimate during a confidential consultation before any work starts, and we will tell you plainly if a case is not worth the money.
Nashville and Middle Tennessee are home base, and we run active casework across East and West Tennessee — Memphis, Knoxville, Chattanooga, the Tri-Cities and the counties between. Through Delator Group's network we can reach any of the state's 95 counties.
Not from us. Every inquiry is confidential from the first call, our fieldwork is covert by design, and reports are delivered only to you or your attorney. Discretion is the product; without it the work is worthless.
That is exactly what they are built for. Reports are time-stamped, photo and video evidence is preserved with chain-of-custody notes, and our private eyes are available to testify when a case requires it. Attorneys across Tennessee rely on Pinnacle for this reason.
