Private detective agency in Sumner County, Tennessee
Sumner County stretches from Hendersonville on Old Hickory Lake to the Kentucky line. Pinnacle's private eyes cover Gallatin and every community in Sumner County with the same lawful methods and court-ready documentation we bring to all 95 Tennessee counties.
A private eye who knows Gallatin and the county around it
Sumner County runs from the lakefront neighborhoods of Hendersonville to the farms around Westmoreland and Portland near the Kentucky line, and Pinnacle's private eyes work the whole range. Hendersonville and Gallatin generate custody, infidelity and cohabitation casework in established subdivisions and lake communities; the county's northern half requires rural surveillance techniques; and the retiree population around Old Hickory Lake makes elder financial exploitation a recurring concern.
We support attorneys at the Sumner County Courthouse on Public Square and the Criminal Justice Center with surveillance, records and witness work, and we serve the county's employers and property managers with vetting, theft and misconduct casework. Because Sumner borders Davidson, Wilson and Robertson, subjects who commute to Nashville are followed there without a handoff.
