Our Company 

The idea for  Sierra Manufacturing was born to merge the best practices of the United States with the passion and dedication and automotive industry powerhouse born in México, thus creating a leader in the manufacture of indexeable inserts. Co-founded by Teri Sue Fagin and Michael Worth Martin in 1995, a feeder factory after the signing of the NAFTA trade agreement.

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