Featuring John Grogan and other examiners when available.
National Intelligence Group can assist with intake and referral to independent polygraph examiners. John Grogan is publicly known as “The Lie Detector Guy.” Additional local and nationwide certified/qualified polygraph examiners may be used depending on availability, location, matter type, and scheduling needs.
Referenced as an independent examiner option, not an employee of National Intelligence Group.
We do not imply Allen personally administers the polygraph. The examiner performs the exam.
Use John when appropriate; use other examiners when location, scheduling, or matter type requires it.
NIG can support the matter with PI services before or after the polygraph referral.
Clients can explain the issue privately before being routed to the right next step.
