Online Distribution of the Fall 2025 Diamond Certified Directory Update Begins

American Ratings Corporation announces the arrival of the Fall 2025 Diamond Certified Directory Update, which features enhanced listings of top rated companies throughout the Greater Bay Area.

PETALUMA, Calif., Sept. 30, 2025 /PRNewswire/ -- This month, American Ratings Corporation (ARC) began emailing the Fall 2025 Diamond Certified Directory Update to more than 820,000 homeowners, local business owners, property and apartment managers, and insurance and real estate agents throughout the Greater Bay Area. There are five versions: North Bay, East Bay, South Bay, San Francisco & Peninsula, and Napa & Solano. Each Diamond Certified company is represented with an enhanced listing that includes their phone number, website, owner/manager info, California license and Diamond Certified Rating Report URL.

Only companies that score Highest in Quality and Helpful Expertise® earn Diamond Certified and are featured in this directory. What really separates Diamond Certified ratings from all others is that a large, random sample of each company's customers are surveyed by phone to get the most accurate ratings and verify only real customers are responding. By surveying from a company's entire customer base, ARC ensures that each company's research results truly represent its customer satisfaction level. And each Diamond Certified company is backed by mediation and the Diamond Certified Performance Guarantee.

As part of their always-free membership, 180,000+ Diamond Certified Preferred Members get immediate access to the Fall 2025 Diamond Certified Directory Update. Diamond Certified Preferred Membership also includes a member hotline, a double Diamond Certified Performance Guarantee, exclusive digital downloads and more.

In recent years, the increase in online reviews has given rise to cherry-picked and fake reviews. Anyone can post a review on sites like Yelp even if they were never a customer, which inflates the company's star rating and creates a false sense of security for consumers. That's why the Diamond Certified Directory has become such an important resource over the last two decades. It's designed for those who care about quality work done by companies that prioritize customer satisfaction.

"People love our Diamond Certified Directory Updates because they can find the most recent collection of local companies that are a pleasure to do business with," says ARC CEO Greg Louie. "The directories are easy to use, too—just download one to your computer, iPad or Kindle and you'll have instant access to hundreds of top rated Diamond Certified companies across a wide range of service industries, from auto repair and remodeling to eye care and plumbing."
