American Ratings Corporation Diamond Certified Revenue and Competitors

Our mission is to define excellence and identify for consumers the highest quality local companies. As creators of the Diamond Certified Program we rate local companies in Northern California on customer satisfaction and credentials. We survey a large random sample of each company's customers by telephone to get the most accurate ratings and to verify that only REAL customers are responding. By surveying from a company's entire customer base, we ensure that the research results, good or bad, truly represent the company's customer satisfaction level. Those that score high in the rating earn Diamond Certified and are backed with our Diamond Certified Performance Guarantee. Each year we publish over 1 million print Diamond Certified Directories and post to our website and social media channels thousands of ratings results, consumer advice articles and video tips from local Diamond Certified Expert Contributors and our writers.
