About Us
Family History
Founded in 2014 by Milan Lubanko, the company carries forward a rich legacy in the aggregate mining industry that spans over half a century.
The Lubanko family's involvement in the industry began in the 1950s with Milo Lubanko, who established Lubanko & Sons and acquired a quarry in the Salton Sea area of Southern California. This venture supplied aggregates, asphalt, and concrete for the burgeoning Mojave Valley. Following Milo's passing, his son, Donald Lubanko, founded Diversified Materials in the 1980s and 90s, dominating the portable crushing market in Southern California. In 1984, Donald expanded operations into the Nuway Landfill to mine sand and cobble for the Industrial Asphalt Company and Owl Rock. After depleting those reserves, he refocused on portable crushing services until selling the company in 1995.
Continuing this tradition, Milan Lubanko established L&G Portable Crushing & Materials to provide specialized portable crushing services across California.
