About DeMark

Originally founded by J. Edwin Hecock and James P. Mumper.


Incorporated in 1984 E & J DeMark originally brought new and innovative grounding products to the Investor Owned Utility and Phone Industry.  Over the next few years, DeMark Inc. continued to grow and penetrate these markets.  Starting in 1995, DeMark moved to a new manufacturing facility and began production, not only of their proprietary products for the Utility and Phone markets but also as a quality manufacturer of screw machined products.  Over the next 15 years the company expanded its capabilities into CNC Lathe, CNC Mill, Centerless Grinding and Swiss Turn technology.

As an ISO 9001 registered and certified company, DeMark has a long history of providing quality and innovation at a competitive price.
