We are a locally run 2nd generation family business owned and operated in the heart of Los Angeles.

Our founder Jaime F. Prieto began Prieto Engineering over 40 years ago as a driveway contractor and slowly grew the company along with his son Giulliano J. Prieto.

As Prieto grew over the years with their valued clients on their side they have been able to self perform the solutions that were requested of them one division at a time.

Over the years Prieto has serviced greater Los Angeles County and has expanded to surrounding counties.
