Private investigator in Plano, Texas
250+ five-star Google reviews
Plano files are often suburban and discreet: family-law documentation, background work, and civil support for counsel who do not want a loud presence on a quiet street. J.I.S covers Plano and Collin County as licensed investigators serving North Texas.
Collin County courts, HOA neighborhoods, and corporate campuses along the Dallas North Tollway create a specific kind of assignment. We handle custody and domestic documentation, process serving that has to be done correctly at a gated address, and locates when someone left a Plano last-known for Frisco or McKinney.
Insurance-defense surveillance happens here when a claimant’s weekday pattern is a campus job and a north Plano home. We also run extensive backgrounds before a hiring or a family placement. You are hiring J.I.S — not picking from a directory.
Work we take in Plano
