Things have to start somewhere. The inception of International Investigative Group occurred twenty-seven years ago in New York, New York. Daniel Ribacoff (founder and CEO of the firm) paired his experience in both law enforcement and the diamond business to undertake investigations that pertained to robberies and fraudulent claims.

Many years ago, when the situation called for special investigation of a situation, I had called Mr. Daniel Ribacoff and his group to the rescue.
He and his team are extremely efficient, knowledgeable, and go above and beyond their duties, and responsibilities, with a specialized personall attention to detail and client.
Should you need an investigations group, the number one firm to deploy, and employ is the Iternational Investigative Group!
Do not hesitate, nor think of anyone else!

I am an attorney and have used IIGPI's services for over 10 years. Dan Ribacoff is an investigator in a class of his own. He has always produced amazing results for my clients and he has helped me prevail in quite a few cases . There is very little that Dan and his amazing staff are not familiar with, and I have never been disappointed by their results. Dan has made me look quite good at times with my clients and the courts. He gets my highest recommendation. More...

When my law firm has a problem, I know how to solve it. It all begins with making one phone call. My issue could be on Long Island, New York City, or upstate, and it does not matter because I know who I can count on. This office works miracles from New Yorkto Florida and back. There is only one number you should know if you need an investigator. More...
