About Us

The foundation of Advantage Tile Stone Design, Inc. was laid thirty years ago by one man installing ceramic tile to support his family.  That one man, through years of hand work sweat, built a company that employed 40 full time tile and stone installers that work on newly built custom homes throughout Southern California.  Today, John Gragg is the CEO of Advantage Tile Stone Design, a company created to bring the latest trends and materials from the world of high end custom homes and commercial buildings.

We are a family run business. Jodi, John’s wife, is President of the company and travels all over the world discovering unique Home Décor items that we feature at our design center.  John’s eldest son Bryan, is head of business operations. Heidi, his eldest daughter, is the Senior Design Consultant, and Adam his middle son, is President of Operations.

It is easy to see our professional quality and workmanship at any of the models of new home tracts.  We are the exclusive tile and stone installers at all S&S homes in Porter Ranch including the Meadows, Tuscany, Sorrento Pointe, and Verona.  In Calabasas, we have worked on the Mont Calabasas community and The Oaks.  In Thousand Oaks, we have worked on the Rancho Conejo Community.  In Camarillo, we have worked on Tesoro Walk and Hidden Park Estates, Agoura.  We have also worked on many tract homes in Bakersfield, Antelope valley, Victorville, and Tehachapi.

Advantage Tile Stone Design Inc. was created to bring the latest trends in new housing and commercial buildings.  We are for those individuals and businesses who want professional and an affordable option.  Our goal is to carry high quality and unique stone, porcelain, and ceramic products and affordable prices without loosing the quality.  With our in house installers, we offer the customer a one stop shop for all of their needs including fabrication.  They can pick out a new floor, place the order, and have it delivered and installed within a very short period of time.  We guarantee the quality and craftsmanship will be at the highest standard and we’ll bring a personal touch only a family run business can offer.  We approach every project as though it is for our own space.
