History

Established in 2006.

Norm Siegenthaler is a native Californian, who moved to Switzerland in 1971. While abroad, Norm completed a machining apprenticeship program at Lehrwerkstaten Bern and moved back to the United States. Norm became a mill operator, and worked his way to Shop Foreman over a period of 14 years.

Sonny Flores is a native Californian who served in the U.S. Army before completing a four-​year apprenticeship with the National Tooling and Machining Association. In 1994, he became a lathe operator, growing to the position of Lead Lathe Supervisor over the next 12 years.

Together, these talented machinists founded Trinity Machining in 2006, each with their own specialty. Their focus is on bringing old-​world craftsmanship to customers at a fair price, and their customer base includes automotive, medical, semiconductor, R&D, military, and other industries.

Not only are they serving international customers, but with parts on the Mars Rover, you could even say they are interplanetary!
