I was fortunate enough to hire Mr. Grayson for an important matter. Mr. Grayson is an excellent Private Investigator and his company is very accessible to the public. I never felt as if I was just another number.

Max Wilson

Very knowledgeable private investigators with excellent customer service skills. Mr. Grayson is the owner and seems to have his hand in all the investigations. I never felt like just a number like I did with the first agency.

Jose Irizarry

We had a client that needed to locate his daughter that was taken to Mexico by the mother without the consent of the father. We notified Det. Grayson and he personally went to Mexico and 2 weeks later the mother was in Mexican custody and our client was on the first plane out of Orlando. You guys are the best and are the only Detective agency and detectives I trust for investigations in Mexico.

These private investigators helped me in Houston and did a wonderful job gathering proof that I needed.

I had a great experience with these private investigators in Houston, Texas. I hired them to watch one of my ex employees that claimed he was injured on the job. They were able to save me thousands of dollars and I just want to tell Ryan Grayson thank you for your help.

The owner of this company personally handled my case. I am very thankful for his services.

I WAS BLESSED TO HIRE RYAN GRAYSON! I found my real father after 25 years missing! I was nervous and did not know what to expect or even which company to hire. From the beginning he was honest, very knowledgeable, and professional. Thank you for your help. I DEFINITELY WILL USE YOUR SERVICES AGAIN!

Anita Perez

Son expertos y estoy muy feliz con sus servicios.

Todd Betancourt

I gained custody of my two children based on the evidence that was collected. I never believed my ex wife was so dangerous until I saw the videos provided by this company. I would recommend International Specialized Investigations to all my friends and family. I really owe having my children to the investigators that went out night after night and recorded her conduct with her lover. Thank you!! Great private investigators!

Adam Ted

I had a great experience with this company. They were very responsive and took care of my situation with great diligence.

Jennifer Seals

Their team did a great job with a task I had that required a private investigator to go to Mexico. They have a great knowledge of getting things done down there and I would use these guys on any future projects.

Clement Investigations

I was in over my head on a case in Ecuador & International Specialized Investigations not only taught me valuable information but went beyond their due diligence to help me find the information I needed to move forward on my case. I recommend this amazing company to anyone needing help in Latin America or any of their investigative needs.

Andres Medina

I was extremely pleased with their services. They found my daughter in Mexico.

Haywood Sawyer

I have used Ryan to help with the recovery of a stolen vehicle from the Central Texas area. I called Ryan and provided him the information. Within the hour, Ryan called back to tell me that he had located the vehicle. Ryan took photographs of the vehicle and confirmed the VIN. Our Repo Driver went to Houston and recovered the car. Ryan saved my client a lot of money and at the end of the day my client was happy. I will only use Ryan for any jobs in Houston or Mexico.

Donna Herrera

DEFENDANT ON THE RUN FOUND IN LESS THAN 24 HOURS! Without the expertise of International Specialized Investigations, we would have never located our defendant and would have had to pay the court a $35,000 forfeiture we would have never been able to recover. We hired another group to locate this individual - they worked this case for NINE MONTHS with no results. ISI found him in LESS THAN 24 HOURS. This is the only group we will ever higher and the only group we will refer to others.

Dalila Mendoza

Estoy muy agradecido por su apoyo.

Lindsay Grace

Ryan is my go to guy when I subcontract surveillance and any additional cases, If your looking for an amazing investigator that has integrity, goes above and beyond for his cases seek no further than International Specialized Investigations. It was a pleasure working with him and would highly recommend Ryan for any future work!
