Why Choose R7 Investigations?

R7 Investigations has been delivering professional, discreet investigative services since 1996. Whether you are an individual, an attorney, or a business, we bring decades of experience and a commitment to accuracy to every case.
We work closely with each client to design an investigation tailored to their specific situation and budget. Before accepting any case, we provide an honest assessment of the likelihood of success and an upfront cost estimate — no hidden fees, no surprises. We are selective in the cases we accept and do not take on every assignment.
All investigations conducted by R7 are legal and confidential and comply with Federal and State Privacy Laws, including the Gramm-Leach-Bliley Act and the Fair Credit Reporting Act (FCRA).
