Established 1904

The Greene Group has been in continuous operation in Warren, Pennsylvania, since its founding in 1904 by G.G. Greene, Sr. The original line of stamped metal products for farming included a top-selling hame fastner for horses. When company leadership passed to Glenn Greene, Jr. the company expanded into a wide range of commercial and defense related products, including high-volume production of ordnance and cartridge holders during World War II.

West Coast Expansion

In the 1970’s, under the leadership of Craig A. Greene, the Greene Group opened several new manufacturing divisions and expanded to the West Coast serving a broad and diverse customer base. In 1997, in response to growing demand for precision metal parts in the high technology and electronics markets, Alexis (Greene) Willingham formed Southwest Greene International, Inc., located in Oceanside, CA.

Britt Joins Greene Group

In 2004, the Greene Group acquired Britt Manufacturing in Port Huron, Michigan, adding important metal and ceramic injection molding capabilities.


Our Oceanside location serves as the Greene Group’s corporate headquarters.
