David, CNC Programmer
Owner of Treun Holdings

David’s career started at a very young age, being a quick learner and having natural mechanical abilities, he looked for ways to quench his thirst for skills and knowledge in the world of manufacturing.  It is a well-known fact that during the Great Depression machinists always had work because something always had to be manufactured.  With this dependable career choice, David dove in with all of his senses open.  While doing his job, David not only learned the task at hand, but also learned valuable skills taking place around him. This attitude enabled him to learn the whole manufacturing process: CAD, CAM and CMM. Being proficient in multiple areas is a great asset when planning a project from start to finish.

The companies David worked for were determined to advance with the times, which gave David the opportunity to improve his skill set. Jobs progressed from manual machines to CNC vertical and horizontal mills (3, 4 and 5 axis), to CAM Programming, CMM Programming and EDM die sinker.  Modeling parts and assemblies in Solidworks is also common knowledge to David.  David bought his own seat of Mastercam software to program on a contract basis and Treun Holdings was born.

David also volunteers as a mentor for a high school robotics team. Using his machining expertise, David teaches these enthusiastic students in safe machining practices. Over the course of 6 weeks, the student’s design and manufacture parts to assemble a robot that competes in a yearly-assigned challenge.
