Our organization is comprised of professionals trained at the National Center for Credibility Assessment (NCCA) in Fort Jackson, South Carolina—the U.S. government’s premier polygraph and credibility‑assessment training institution. NCCA provides advanced instruction to the FBI, Secret Service, CIA, and more than 25 federal agencies, and our examiners uphold the same rigorous standards.

Collectively, our team brings an exceptional depth of experience in criminal and national security investigations. Members have operated in complex, high‑risk environments where precision, discretion, and analytical discipline are essential. This background includes extensive training in sophisticated investigative methodologies, advanced interview strategies, and credibility‑assessment techniques that have been relied upon in both federal and state judicial proceedings.

Most people seeking a polygraph examination have never needed one before. They’re often dealing with stress, uncertainty, or serious allegations—and they may not realize that the quality of the examiner can make or break the value of the results.

The truth is simple:

Not all polygraph examiners are the same.

And choosing the wrong one can lead to results that are unreliable, misleading, or dismissed entirely.

Summit Polygraph stands apart because we bring a level of training, experience, and professional discipline that most firms simply do not have. Summit Polygraph LLC’s unique combination of federal‑level training, real‑world investigative experience, and strict adherence to validated protocols allows us to deliver examinations that stand up to scrutiny. We bring the same level of professionalism to every case—whether it involves a criminal allegation, a workplace concern, or a deeply personal matter such as infidelity.

At Summit Polygraph LLC, we are expertly trained & certified in the utilization of sophisticated investigative and interviewing techniques.

Credible. Ethical. Reliable.
