Investigation, drafted with precision.

A trestleboard is where a plan takes its final shape before the real work starts — and that's the standard behind every case we take on. Trestleboard Investigations serves Nashville and the surrounding Middle Tennessee counties with licensed private investigation services built on a clear methodology: careful intake, a documented plan, disciplined fieldwork, and a report you can actually act on.

As a Delator Group company, Trestleboard draws on statewide resources, a dedicated process serving division, and a corporate structure that keeps every case accountable to a single senior point of contact — not a rotating cast of subcontractors.

Plan First

Every case starts with a clear, documented plan before any fieldwork begins — no wasted hours, no guesswork.

Licensed & Accountable

Tennessee-licensed investigators operating under Delator Group's corporate structure, not independent contractors.

Reports You Can Use

Findings are delivered in plain language with full documentation, built for attorneys, courts, and everyday decisions.

Ten services, one disciplined methodology.

Nashville has no shortage of investigators willing to take a retainer and disappear for weeks. Trestleboard was built around the opposite instinct: every engagement, whatever the service, follows the same disciplined sequence — a documented plan, careful fieldwork, and a report built to be used, not just filed away.

That consistency is what lets Trestleboard move between an infidelity case on a Tuesday and a corporate due-diligence review on a Thursday without dropping the standard either one deserves. The plan changes with the case. The discipline behind it never does.

Clients come to Trestleboard through family law attorneys, HR departments, insurance adjusters, and plenty of people who've simply run out of other ways to get a straight answer. Whichever door you came through, the process from here is the same.
