Whether you are dealing with a relationship dispute in Somerset, investigating workplace misconduct in Gloucestershire, or preparing a legal case in Devon, we provide the same structured, transparent methodology for every client. Our evidence-led approach is grounded in the standards of the American Polygraph Association (APA) and ASTM International Committee E52 on Forensic Psychophysiology.
