As a criminal defense team practicing in Texas for over three decades, we've worked with many investigative firms—but Gradoni and Associates truly stands out. They’ve been in the business for many years and have built a solid, well-earned reputation for delivering results. Their proven track record is one of the reasons we first reached out, and they’ve exceeded expectations every step of the way. Their communication is excellent—always responsive, professional, and clear. The reports they provide are detailed, thorough, and easy to work with, which is critical when building a solid defense. Turnaround time is consistently quick, and they never cut corners. What really sets them apart is their team. Gradoni and Associates offers a variety of experienced investigators, each with their own area of expertise. No matter the challenge, they’ve had the right person for the job. It’s been a pleasure working with them, and we wouldn’t hesitate to recommend Gradoni and Associates to any legal professional looking for dependable, high-quality investigative support. -David Kiatta, Segura & Kiatta Criminal Defense

Our firm Bivona Law uses Gradoni & Associates to track down individuals related to motor vehicle accidents. I've worked with them on several occasions and each time they have provided exceptional service. There is no other company I would trust to get the job done. I'd use them over and over again!

Hired Gradoni and Associates to help with a legal matter. JJ offered insights, suggestions, cautions and even a much-appreciated compassionate ear. His team followed up without relenting, eventually giving us a great laugh when a young woman, “Kitty Cat” was able to serve, “Determined Dodger” while dressed up on Halloween night! This act alone provided us with a key, but reluctant witness, who helped to cinch our case. JJ’s team went above and beyond in conducting surveillance, background searches, finding what we believed he would find and then providing top-notch reports for court. Through the process, we were kept informed of all the details. Victory is sweet and satisfying, JJ is balm for battle wounds, a determined force and a man of honor, doing what he says he will do with all diligence. His is team is professional, thorough and committed. No regrets and very thankful! JJ came through for us. The huge lesson I’ve learned in all of this… when heading to court, take no chances with who is on your team!
