I used Gradoni on an employment fraud matter from 700 miles away. They were incredibly thorough and most importantly were able to deliver the truth I was looking for. Their final report helped us settle the matter without question. Mr. Gradoni was very involved and was very easy to work with. I highly recommend this business.

I contacted Gradoni & Associates to check out a sketchy moving company (who was already in my house). Keith was extremely helpful and prompt. He ran a quick background check, gave me tips and advice on what to do next. I can't thank these folks enough!

I hired Gradoni and Associates to help me with a background check on a family member who I've been suspecting of not being the person they claimed to be. They worked my case with care and haste. The owner J.J. Gradoni is a nice guy. He actually saved me money and never tried to upsell me on anything. They never did anything without my approval and I really appreciate that. I HIGHLY recommend Gradoni and Associates. I had nothing but a positive experience with them and will return if I need anything else.

I hired Gradoni & Associates to locate a missing at risk close relative. Keith Kucifer worked on my case diligently every day with very little to go on other than a last known location from two months prior. He updated me each day on what progress he had made and his plans for the following days. Within two week's time, he was able to tie down a probable location area and a phone number.

He had found him! I was thrilled, as I had given up hope that the police department would ever be able to locate this missing person. I recommend Gradoni & Associates for their professionalism and dedication to each case. They get the job done!

JJ and his team are fantastic. My ex is really difficult and avoids service. Twice I've had yo use Gardoni and Associates and both times they were successful in less than 24 hours when process servers and constables couldn't get the job done. My ex likes to hide behind gates, secretaries, and private parking garages, but he's no match for JJ and team!

I never thought I'd be in the position of having to hire a PI; JJ made the time to explain processes to me and his pricing is very fair. He made me feel comfortable and I trusted he'd get the job done.and he did. I will not hesitate to call on him again if goodness forbid I need to and I recommend him whole heartedly. Honestly there aren't enough stars to rate him as highly as I want to.

JJ's got it all! He was able to surveil (at very short notice!) someone for a child custody case. The reports were well-written; easy for a jury to understand, and even had photos. We would highly recommend JJ to anyone searching for a discreet, reasonably-priced P.I. Thank you JJ! Susan and Tim

Google had a lot to offer in the Houston area, HOWEVER, when needing answers and assistance I followed my gut intuition and it was SPOT ON.

I have had the pleasure of working with JJ and his staff at Gradoni & Associates on a number of occasions. Their expertise in the private investigations field is quite amazing. The background searches they conduct are thorough and have helped my business and I make a number of important decisions. I would highly recommend Gradoni & Associates to anyone for background checking or private eye services.

They came through for us on our case. I though I was being railroaded on my case, the police didn't believe us, and I thought I was finished. When my lawyer Jack B. Carroll hired a private detective to investigate my claims, I thought he was just trying to raise my legal bill, but when the investigator came to court and testified on my behalf, with evidence that they got from God knows where, I knew the light was gonna shine on me. Even though I don't know these guys, my freedom is a testament to their expertise as private eyes. Thanks guys!

They handle their business with silence, and provide comprehensive data, video, images, and detailed investigation reports. I don't care to share much about our relationship, but I can certainly recommend Gradoni & Associates if you're looking for one of the best investigators in practice and ethics.

When I thought he was cheating on me I figured I was just having unfounded suspicions. I'm glad I didn't marry that bastard. Thanks JJ for showing me the truth. A sharp gentleman and a great private eye. The investigation report was very detailed and I could make out everything and every face that I saw in the surveillance photos. Thanks for everything.
