Dylan Graffious
As the owner of Southwest Polygraph, LLC I am proud to offer reliable and affordable polygraph (lie detector) 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 the Arizona Polygraph Association.
I have extensive experience conducting polygraph examinations and investigations involving law enforcement applicants, sworn and civilian employees, specialized unit candidates, internal affairs matters, criminal investigations, and private clients. I previously worked for two of the largest law enforcement agencies in Arizona, where I conducted background investigations and polygraph examinations for sworn officers, civilian employees, and specialized assignments.
My background also includes serving as a background investigator, interviewing and interrogating suspects and witnesses, preparing detailed written reports, and testifying in court as an expert witness.
In addition to my field experience, I am actively involved in advancing professional standards within the polygraph community. I previously served as a Board Member of the Arizona Polygraph Association and currently serve as the Vice President for Law Enforcement and Government Examiners, helping support ethical practices, continuing education, and quality assurance within the profession.
Clients often come to me during stressful or uncertain situations. Whether you are seeking clarity in a personal matter, verifying information during an investigation, or fulfilling an employment or probation requirement, my goal is to provide a professional, respectful, and judgment-free experience while delivering results you can trust.
If you are looking for a reliable Arizona polygraph examiner, private lie detector testing, or law enforcement polygraph services, I would be honored to assist you.
