Diamond Certified Resource’s ratings of local companies are based on surveys of only verified real customers, so they are the most accurate.

Each company report includes detailed quality ratings and scoring, verbatim customer survey responses, a profile video, a company story video, a capabilities table, a photo gallery, researched articles, unique expert contributions from the company’s owner, and more.

This sounds good, but it has led to company profiles that are littered with false claims and incomplete info.
