After being badly let down by another investigator who took my money and failed to do anything to assist me, I was recommended to Adrian of Group One Investigations. It was a pleasure to deal with Adrian who acted promptly, delivered exactly what he said he was going to do, and all for a very reasonable fee. Very professional and highly recommended.

Was nervous about using private investigator, wasn't sure what to expect.
Adrian was great he stated clearly what was needed to start and that there was no charge if he cannot locate the information. He was friendly and helpful.
