Vice President

With more than 20 years with JR Machine, Parker drives the company’s vision forward to simplify the customer experience. Working directly with customer engineers to understand the critical functions of each part, Parker leads the team to focus on those features while simplifying everything else — to provide exceptional value.

Parker enjoys manufacturing solutions that can be seen in everyday life. He notes that there is not one day that goes by that he doesn’t see one of our parts out in the field in some of the coolest products in the world! When Parker isn’t in the shop (which he says is pretty fun on its own), you can find him spending time with his wife Stephanie and his daughter Ivanna.
