Find the truth in any situation


In business since 2003

As a former Detective Lieutenant with the Service de police de la Ville de Montréal, I have over 3 decades of experience in lie detection and polygraph testing. Thanks to the quality of my services, I have built an unparalleled reputation across Greater Montreal.

This led to my position as a trainer at the Canadian Police College. No matter what your suspicions, rest assured that I have the capabilities to help you know the truth.

At the end of any investigation, I prepare a detailed report, in compliance with current legislation.
