Alpha Investigation Services from Italy to Australia. I needed to find "invisible" relatives and with great professionalism, courtesy and dedication in their work, they were able to solve my problem. I thank immensely for their availability and kindness. I believe that if I need to, I will call Alpha Investigation Services again because for me they are number one .... I live in Italy and for them there are no borders! HIGHLY RECOMMENDED

This was my first time using a private investigator, I strongly recommend it to anyone who is going crazy with worry. From the very first phone call I had with Alpha Investigation Services I was able to stress less. Pete was professional, kind, and empathetic. He really took the time to listen to me and understand my situation. Thankyou for everything you have done for me in locating my brother. Im more than happy to recommend Alpha Investigation Services to anyone.
