Jon Dumas, Commercial Manager at GTI Manufacturing

Jon Dumas

Commercial Manager

Jon has been in the custom engineered parts industry since 1996. He got his start in the infancy of stereolithography and found his passion working with product development engineers and new technologies.

Jon was a business development manager for a CNC machine shop focused on aerospace and defense machining and electro-mechanical assembly. It is here that he came across thixomolding while trying to help a customer reduce part cost, and where he met Greg Raleigh. In 2004 Jon created GTI Manufacturing to specialize in part sourcing, new process technologies, and supply chain management for military, defense, automotive, and consumer OEMs.

Jon is based in Houston, TX.
