Truth Verification:
It is just as important for our polygraph test results to verify a truthful statement as it is for us to identify a deceptive statement. Everyone benefits from the truth. Our polygraph instruments can verify a statement's accuracy.
We can also conduct detailed interviewing at your discretion. Interviews are conducted before and after a polygraph examination or can be done alone. A thorough unbiased interview may help you make decisions.
