About Us

Tamshell began in 1980, when John Hernandez and Art Pierce opened up a machine shop in South Los Angeles County, California.  Their passion for machining opened up big possibilities for their success which has culminated in what Tamshell has become today.

Over the decades, Tamshell has continued to grow and expand our operations. We’ve built trusted partnerships with companies from Aerospace & Defense to Oil & Gas sectors.

Today, as we prepare to expand our facilities and capabilities again, our Quality Promise has remained since day one.

We appreciate your patience as we re-imagine our new website.  Should you have any questions at all, please do not hesitate to reach out to us.
