Testimonials for Cristelle:
I can highly recommend Cristelle at Australian Polygraph Services. She was professional and friendly. She took the time to fully explain the test process and answer my questions. Cristelle did not judge me or my circumstances, she provided an unbiased test in a proficient manner. I was given an immediate verbal outcome and CD copy of the recording and later that day I was emailed the full detailed report.
I felt at ease during the whole process and overall I was extremely happy with her services.
I would like to recommend Australian Polygraph Services to anyone considering having a polygraph test. I base this recommendation on the professional manner of conducting the polygraph test with a qualified and very experienced tester named Cristelle. I had a polygraph test done some months prior with another polygraph company which was conducted in the privacy of a home visit, there were several questions asked which I believe possibly flawed the test and left room for error and misinterpretation and did not entirely focus on the main question and the issue at hand whereas Australian Polygraph Services focused on a precise accurate direct statement pertaining to the main question and issue at hand to leave no room for error or misinterpretation. The testing procedure was explained in detail. A discussion with both parties took place to determine the matter and issue at hand to ascertain the main question to bring about and get the best and most accurate result possible regarding the polygraph test. A pre test interview and assessment was also conducted. The outcome of the test was transparent, there was no discussion of the results until both parties were present. A video and audio tape of test was given on the day, the results were sent to both parties by email within 24 hours. I would highly recommend Australian Polygraph Services to anyone seeking a professional service with value for money that cost a considerable amount less than the other company.
