Professional Polygraph Examiners

Best Polygraph Examiner and Lie Detection in Southern California

Our lead polygraph examiner is FBI-trained, having worked as a Special Agent for the FBI for more than two decades, and became a Senior Polygraph Examiner for the Los Angeles Division managing the Polygraph Program for the second largest office for the FBI.

Not only does our lead polygraph examiner know how to conduct a flawless lie detector test, but he has the experience to facilitate a successful exam that provides trustworthy results that will stand up to the highest scrutiny.

Our lead polygraph examination expert actually created the I&I training curriculum for FBI – Los Angeles, which became mandatory training for Probationary FBI Special Agents. He has also presented at DEA, CIA, DSS, and many local Police Departments.

We have office locations in Beverly Hills and Calabasas, California, as well as the ability to bring the lie detection facilitators to your home, business, or office. Besides Los Angeles, CA, we work throughout the United States, Mexico, South America, Britain, France, Germany, and many other countries around the world. 

Trusted and Professional Lie Detection Tests, Polygraph Examination Services, and Private Investigations in Beverly Hills and Calabasas, California

Se habla Español! 

We offer polygraph examination services performed in English and Spanish. In order to get the most accurate results in a polygraph examination, the way questions are phrased matters—it matters a lot! Simply translating the idea in another language is not good enough. Each word and conjugation change the meaning of a sentence or question and may alter the outcome and accuracy of the lie detection exam. Our lead polygraph examiner expert has spoken English and Spanish since he was a child and is well-versed in grammar accuracy, dialect, and cultural phrasing. Simply having someone who “speaks Spanish” is not enough; you must have a professional polygraph specialist who knows the language in and out with native language abilities.

      How the Polygraph Examination Process Works

      Initial Consultation

      During the initial consultation, our team will decide the best time and place for the polygraph examination. We will discuss the issue and the best line of questioning.

      Exam Preparation

      On the day of the exam we will prepare the space where the polygraph will be conducted. We tell whoever is going to be taking the exam to continue their normal, daily routine. If the person normally drinks a couple cups of coffee in the morning and has a workout regime, we tell them to adhere to their normal activities. 

      During the Exam

      For the actual exam, there are a few things we tell the person to be mindful of:

      1. Sit still and relax.
      2. Pay attention to what is being asked and focus on what you are saying.
      3. Tell the truth.

      After the Exam

      Following the polygraph test, if the client prefers, we can have our examiner discuss the results with you and provide a written, professional report.

      Commitment to Professional Standards

      We adhere to the strictest standards, ethics, and methods, maintaining confidentiality and professionalism from start to finish in the process. Our polygraph examiners are active members of many associations and industry organizations:
