Ready mixed concrete Orange County – A & A Ready Mixed Concrete, Inc was created in 1949 in Gardena, CA with nothing more than a truck and a trailer. Over the years, the company has grown steadily throughout Southern and Northern California. This expansion has led to the addition of several subsidiary companies, including Southern California based Associated Ready Mix and Northern California based A & A Concrete Supply. The company is owned by Kurt (President and CEO) and Randy Caillier (Vice President). And today, with dozens of plants and hundreds of trucks, A & A has become the largest family-owned supplier of ready mixed concrete in California.
