I do not have experience with Dr. Tebbs, but it appears his methods are essentially conventional and evidence-based with regard to tools. The principal value would be in his commitment to integrating multiple data sources from as many aspects of an individual's existence as accessible, and any clinical expertise he has.

Also, he is selling a data organization and interpretive tool to professionals. I don't hold that against him, though.
