Company Info


The company


DelGrosso Design was founded in 2002 by Andrea DelGrosso when he moved to Santa Rosa, California from Lake Como, Italy. During the years Andrea's personal and technical growth has pushed the company through different phases. In the first years of business in California DelGrosso Design has been mostly installing outdoor concrete, stone and masonry, trades that Andrea learned from his father and grandfather. In the following years Andrea became fascinated by the creativity and beauty of decorative concrete, so he started shifting the direction, focusing mostly on concrete installation and restoration. The desire to create more beautiful and unique projects brought out the need of exploring new and  unique applications for concrete interiors, like diamond polishing, custom staining and stenciling.


We are proud of every project we complete and of our customer care. We make a mission of listening and understanding our clients, steps too often underestimated by our competitors. We believe that the quality of every project it is not only in the beauty of the final product, but also in the entire construction process necessary to get there.
