I spent $1000 to have Adam surveil and serve a respondent. Not only was he unable to get her served, but he did not tender the required and appropriate documentation or affidavit. I have called and left several messages as well as sent multiple emails but Adam Campbell and his son were much more responsive prior to getting paid; thereafter, communication ceased.

I have worked with Adam Campbell over the last 34 years on complex personal injury and criminal cases and have never been disappointed by the quality of service and integrity of him and his company. I have used Adam to locate and serve witnesses, obtain witnesses statements, photos and videos of crash scenes and surveillance work.
