What Our Clients Say
"I engaged Thomas after my young son was abducted from China and taken to NZ. After speaking to many PIs, my lawyer recommended Thomas. Thomas quickly located my son, ensured he was safe and even took his passport so he could not leave NZ. In less than 72 hours, my son was located and was on a plane back to China. Thomas and his team went the extra mile to ensure the safety of my son and I, and was available at anytime to reassure me."

Google Review"I am incredibly impressed with the investigation services provided by Thomas. His efficiency and dedication were outstanding, going above and beyond my expectations. Notably, he delivered a comprehensive report on the same day, exceeding the required information. This was in stark contrast to a previous experience with an agent from a different company, who left the job unfinished, charged excessively, and lacked any guarantee of confidence. Thomas's professionalism and exceptional service have set a new standard for me, and I wholeheartedly recommend his services to anyone seeking reliable and thorough investigative work."

Google Review"I am extremely pleased with Thomas's exceptional service in collecting a $1.4 million debt for me within just two weeks. I contacted Thomas on a weekend and he immediately replied and was able to meet me the following day. Thomas' efficiency, professionalism, and results exceeded my expectations. I highly recommend Thomas and ISACORP."
