Private detective agency in Washington County, Tennessee
Washington County is home to Johnson City and East Tennessee State University. Pinnacle's private eyes cover Jonesborough and every community in Washington County with the same lawful methods and court-ready documentation we bring to all 95 Tennessee counties.
A private eye who knows Jonesborough and the county around it
Washington County is Tennessee's oldest county and one of its most active in the Tri-Cities. Johnson City's economy is built on East Tennessee State University, the Ballad Health medical center and the James H. Quillen VA, which produce custody and infidelity casework, healthcare vetting and workers' comp matters, and a student and young-professional nightlife scene downtown. Jonesborough and the county's rural communities toward Limestone and Fall Branch require the rural techniques Pinnacle uses across East Tennessee.
We support attorneys at the Washington County Courthouse in Jonesborough and the Johnson City courts with surveillance, records and witness work, and our Tri-Cities teams cover Sullivan, Greene and Carter Counties from the same base.
