John Hamilton2026-06-18I came to Marc during one of the most stressful times of my life, desperately trying to locate someone I had lost contact with. From the very first conversation, he was professional, compassionate, and straightforward about what the process would look like. He never overpromised — but he delivered beyond what I expected. Marc worked quickly and kept me updated every step of the way. Within a shorter timeframe than I anticipated, he had the information I needed. His attention to detail and the thoroughness of his work gave me complete confidence that I was in good hands. What really sets Marc apart is how he handles the human side of these situations. He understood how emotional and urgent this was for me and treated my case with real care — not just as another job. That meant a lot. If you need someone discreet, reliable, and genuinely skilled at what they do, look no further. I wouldn’t hesitate to recommend Marc to anyone. Absolute professional. 10/10.
