Brian was very thorough and timely in my request to locate my missing son. He was able to locate my son within a few weeks even though he was across the country! Brian went the extra mile and personally made the trip to save time and money which brought a very worried mom some comfort and reassurance of my sons safety.

I would highly recommend McDonald & Associates for any kind of investigative work as they were very responsive to my request, stayed within my budget and got results very quickly.

Phenomenal experience working with this firm on a complex issue. The investigators were thorough and easily adaptable to shifting requests and priorities. Brian, especially, went out of his way to ensure the best possible service and even helped craft a backup plan in case our course of action was interrupted.

Would recommend them to colleagues in the field and cannot wait to use them again.

During a recent meeting, the doctor commented that the professional presentation and clarity of the video was instrumental in his ability to positively identify the claimant and observe/assess the movements of the injured body part.

The doctor said that most surveillance video he’s watched in the past was so shaky, grainy, and of overall poor quality that it was of almost no value from his perspective.
