About Serrano Industries

For When You Need it Yesterday

Our history

At twelve years old, Hoberto Serrano already knew that he wanted to run his own business someday. A natural entrepreneur, Hoberto had plans for his own manufacturing company when he completed technical school in Los Angeles in 1985. After working and gaining experience at several local machine shops, Hoberto founded Serrano Industries in 1989.

Serrano Industries started with one machine in 400 square feet in Paramount, California. From these beginnings, Serrano has grown into its own 30,000-square-foot building with twenty CNC mills, nineteen CNC lathes, wire EDM capabilities and dozens of talented employees. “From the beginning, our goal has been to build long-term relationships with our customers,” explains Hoberto Serrano, president. “We accomplish this by ‘being there’ when you need us. Whether your requirement is for a complex prototype ‘overnight’, close-tolerance connectors from high-temp alloys, or thousands of precision parts, Serrano Industries has the will, the people, and the experience to make it happen.”

“Working Hard to be the Best in the Businesss”


Serrano Industries has raised the bar for customer service with our unique “Serrano Express” service.
