Greg Tucker’s 15 years of Investigative Experience

G.A. Tucker P.I. Investigative Services L.L.C’s investigative team uses both experience and education to effectively solve investigative issues in an effective and professional manner. Though most Private Investigative firms have investigators who have years of experience, most of them lack the formal education needed to provide an analytical approach for their clients. At G.A. Tucker P.I. Investigative Services L.L.C., our investigators not only have several years experience in Law Enforcement, but also hold Master’s Degrees in Criminology, Forensic Behavioral Science, Legal Studies, Education and Psychology. We believe for an investigator to be effective, one must understand human behavior and have the experience to solve the task at hand. We provide this unique and diverse pedigree to our clients.
