Accurate ratings. We survey a large random sample of each company's customers by telephone to get the most accurate ratings and verify only REAL customers are responding. This ensures the research results, good or bad, truly represent the company's customer satisfaction level.
Highest in Quality. Our ratings process of local companies is the most accurate in the Bay Area. Companies must score Highest in Quality in customer satisfaction, a 90+ on a 100 scale, and pass all of our credential-based ratings. Most companies can't qualify.
Ongoing research. Companies must keep up their high performance. If they don't, they are removed from Diamond Certified. We never allow a Diamond Certified company to sit on its reputation.
