John Gervino

Science-Based Deception Detection Trainer & Consultant & Former DHS Special Agent & Mobile Interrogation Team Leader for the High Value Detainee Interrogation Group

As the founder, trainer, and lead consultant for Truth Intelligence Consulting, John Gervino teaches business and law enforcement professionals science-based interview, interrogation, and deception detection techniques that enable non-coercive and reliable truth discovery.

Simply put, we train professionals to differentiate between truth and lies using evidence-based methods for assessing verbal cues.

John spent 24 years as a U.S. federal agent, primarily engaged in counter-terrorism operations which led to the apprehension and interrogation of foreign terrorists. In 2012,  John was one out of 240,000 Department of Homeland Security employees to lead an elite team of expert interrogators assigned to the High Value Detainee Interrogation Group (HIG). From 2012 to 2017, he served as a Mobile Interrogation Team (MIT) leader and lead interrogator.

By implementing and honing reliable verbal-cue based interrogation methods, John and his team embraced the core mission of the HIG “to deploy the nation’s best available interrogation resources against terrorism detainees … to prevent terrorist attacks against the United States and its allies.”

Today, John seeks to transform the practice of lie detection and interviewing by incorporating those same science-based methods in both the private and public sector.

Reliable deception detection is a powerful tool, which is why he offers consulting and workshops for a wide range of industries and professions – from, finance, and law to private investigation. John also trains federal agents and law enforcement personnel domestically and internationally and on the science behind verbal-cue based deception techniques.

Participants have found John’s workshops to be highly valuable learning experiences. Contact him to find out how to use science and verbal cues to detect deception, improve your interview or interrogation skills, and mitigate risk.”
