Dylan Graffious

As the owner of Southwest Polygraph, LLC I am proud to offer reliable and affordable polygraph examinations to individuals, therapist, businesses, and government agencies. My goal is to help uncover the truth by using evidence-based practices outlined by the American Polygraph Association and Arizona Polygraph Association.

With experience working for two of the largest law enforcement agencies in Arizona, I have conducted thousands of polygraph examinations. I understand that trust and integrity are essential in the polygraph industry. That's why I have implemented strict ethical standards and training to ensure accurate results. Being highly skilled and having gone through rigorous training, ensures I can provide the highest level of accuracy possible. As a member of the American Polygraph Association, American Association of Police Polygraphists, and the Arizona Polygraph Association, I am committed to keeping up-to-date with the latest developments and advancements in the field.

At Southwest Polygraph, LLC I take great pride in providing evidence-based practices to my clients. I believe that the polygraph can be a powerful tool in helping to determine the truth in many situations. As such, I am dedicated to using the most advanced techniques and technology available to ensure that my clients receive the most accurate and reliable results possible.

Over the years, I have worked with a wide variety of clients, including law enforcement agencies, private investigators, and individuals seeking to clear their names. Whether you're looking to integrate the use of polygraph in sexual addiction recovery, conduct a pre-employment screening, or simply need to verify the truth of a particular situation, I have the knowledge and experience needed to help.

Our examination process is designed to be comprehensive and thorough. I work closely with our clients to identify the specific questions they need answered, and tailor the approach accordingly. I also provide a detailed pre-test interview to help ensure that the examinee is calm and relaxed before the examination begins.

During the actual examination, I use state-of-the-art equipment to measure physiological responses to questions. I analyze the results using the most up-to-date scoring algorithms, and interpret the results in a clear and concise manner. I encourage clients to ask questions or voice their concerns about the process or results.

How It Works

  • Phase 1

    Pre-Test Interview:

    During the initial meet and greet, our examiner will review the forms and questionnaires with the examinee, gathering all necessary information to tailor the examination to your specific needs.

  • Phase 2

    Data and Chart Collection:

    Our certified examiner will administer the actual test using state-of-the-art equipment to measure physiological responses to questions. The sensors we use include a blood pressure cuff, corrugated rubber tubes for chest movement, metal fingertip tabs for sweat gland activity, and a clip on the middle finger to measure changes in blood volume.

  • Phase 3

    Post-Test Interview:

    Once the examination is completed, the examinee will have the opportunity to discuss any concerns or provide additional information before the session concludes. We offer a comprehensive written report upon request, summarizing the examination results.
