Our Company History

The idea of Sierra Manufacturing was born to fuse the best practices of the United States with the passion and dedication of a nascent automotive power in Mexico, thus creating a leader in the manufacture of indexable inserts. Co-founded by Lic. Teri Sue Fagin and Eng. Michael Worth Martin in 1995, as a secondary factory after the signing of the NAFTA trade agreement. 

Today the company is owned by his son, Lic. Andrew Michael Martin, whose experience in international business and technology positions the company for future growth focused on manufacturing 4.0.
