The Truth Makes
A Difference.
For over 35 years, Gradoni & Associates has provided licensed investigative services to Houston's legal and business community. Our investigators, former police detectives and federal agents, support corporate counsel with due diligence and workplace investigations, assist attorneys with civil and criminal casework, and conduct the surveillance and background work that both individuals and institutions rely on. Every case is handled with the discretion and documentation standard our clients expect, whether the audience is a jury, a judge, or a board of directors.

Why Gradoni & Associates
Former Law Enforcement. Corporate-Grade Documentation.
Founded in 1988 by retired law enforcement officer J.J. Gradoni, our team includes former police detectives and federal agents who bring the same standard of documentation to a corporate boardroom that they once brought to a courtroom. Attorneys and corporate clients return to us because our reports are built to be challenged and to hold up anyway.
