Honesty first, since that is our entire business: we do not have an office in Mercerville-Hamilton Square. This Mercer County community of about 26,000, part of suburban Hamilton Township outside Trenton, is served by our Trenton-area office at 2564 US-1, Lawrence Township, NJ 08648. The office sits 3.9 miles from Mercerville-Hamilton Square — a drive of roughly 7 minutes, shorter than most trips across Hamilton Township itself.
Being minutes from New Jersey's capital region means clients here get big-city polygraph resources without big-city travel. The office maintains a dedicated examination suite: a quiet, private room with controlled conditions, because accurate polygraph charts depend on eliminating background noise, interruptions and onlookers. That is also why we never test in kitchens, offices or hotel rooms.
When you arrive, a professional examiner — trained at APA-accredited polygraph schools — walks you through a structured pre-test interview, reviews every question with you before the instrument is attached, then conducts the examination using computerised equipment. Charts are analysed the same day, and you receive a written report before the matter has a chance to fester any longer. Pricing for Mercerville-Hamilton Square clients: $600 for a standard single-issue examination, $1,000 for couples, and $475 per person for group testing.

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 Trenton office is approximately ~7 min from Mercerville-Hamilton Square. 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 Trenton.
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.
