For over a quarter century, Sosa Granite and Marble has provided natural stonework for a wide range of residential and commercial clients throughout Northern California. During that time, the Sosa family, owners & operators of Sosa, have built a stellar reputation based on dedication to produce excellent personal service.
Mario Sosa has been in the trade for 28 years. For his first 10 years he rose to a position of lead supervisor at one of the biggest companies in the bay area. Mario always requested the most complex jobs as he enjoyed the challenge and satisfaction upon completing and mastering the most difficult job. At this point, Mario felt the need to expand his passion and decided to start his own business in 1987. Marios goal was to pursue excellence for every job which led to many referrals. Mario was faced with a dilemma of turning jobs down or expanding his new thriving business. Soon he hired his first employee and instilled his values on him and before long Sosa Granite and Marble now has 70 employees. Mario oversees all aspects of the business, however he also made a great addition to the team in 2000 by imparting his vision and goals into the VP of the company, Mario Jr.
