Mr. Mario Eulogio Blanco came to America in 1963 from Costa Rica. Lou, his son, was 3 years old. It was soon after his arrival in the United States that Mario began his plumbing career. By digging for local plumbers as a way to provide for his family, Mario eventually started his own plumbing business. Lou Blanco was trained up as child and retained Mario's work ethic to continue his fathers legacy. Now, nearly half a century later LG Blanco is one of the leaders in industrial, commercial, and residential plumbing in California
