Here is the plain geography: Thornton has no polygraph office, but our Westminster suite at 9191 Sheridan Boulevard, Westminster, CO 80031 is just 4.1 miles away — a drive of roughly 7 minutes. Few of our "nearby city" pages describe a shorter trip.
Thornton is one of the north Denver metro's biggest suburbs, an Adams County city of about 133,500 that has grown rapidly along the I-25 corridor with young families and commuters. Its polygraph needs are the metro's in miniature: partners seeking certainty after suspicion, parents and siblings resolving accusations, and employers along the corridor investigating specific incidents of theft or misconduct. All of it lands at Westminster, minutes away.
The reason we still ask you to make even that short trip — rather than sending an examiner to your living room — is that the examination room is part of the method. The Westminster suite offers controlled acoustics, complete privacy and zero interruptions, conditions no home can certify. There, an examiner trained to APA standards agrees every question with you word-for-word, runs validated single-issue charts, scores them on site, and hands you a written report the same day. A single examination is $700, couples testing is $1,200, and groups are $650 per person.

Preparing for Your Visit
Travelling to your polygraph appointment? These tips will help you arrive prepared and get the most accurate results.
Plan Your Journey
Your appointment at our Westminster office is approximately ~7 min from Thornton. We recommend arriving 10–15 minutes early — rushing to your appointment can elevate your heart rate and affect your physiological baseline, which could impact accuracy. Plan for traffic and allow a small buffer.
The Night Before
Get a full night’s rest. Fatigue affects physiological responses and can interfere with the accuracy of your polygraph results. Avoid alcohol the evening before, and try to maintain your normal routine as much as possible.
What to Bring
Bring any relevant documents — case notes, a list of questions you want covered, or reference materials. If someone is accompanying you, they’re welcome to wait in reception while the examination takes place in a separate private room.
On the Day
- Avoid caffeine and stimulants — coffee, energy drinks, and nicotine elevate heart rate and can affect sensor readings
- Eat a light meal — don’t arrive on an empty stomach as sessions typically last 90 minutes to 2 hours
- Wear comfortable clothing — sensors are placed around the upper body, so avoid tight or restrictive layers
- Bring valid photo ID — your examiner will verify your identity before the examination begins

Why Our Results Are Trusted
The science behind our polygraph examinations at Westminster.
Accuracy Rate
When administered by a qualified, APA-qualified examiner using validated protocols, polygraph testing achieves 90–95% accuracy in specific-issue testing, supported by decades of peer-reviewed research.
Question Repetition
Every relevant question is repeated a minimum of three times during your examination. This multi-pass approach eliminates anomalies and ensures the physiological data is consistent and reliable.
Channels Monitored
Our digital instruments simultaneously monitor heart rate, blood pressure, respiration (thoracic and abdominal), and electrodermal activity — providing a comprehensive physiological profile throughout the examination.
Validated Technology
The polygraph is the only scientifically validated technology for truth verification. We reject unvalidated alternatives including voice stress analysers, mobile apps, and eye-tracking tools.

Our Westminster examiners provide detailed written reports suitable for legal use, and are available for expert testimony if required.
