The Team

Our work environment encourages teamwork, self-discovery, and personal interaction, which means that rarely will one come to work and do the same thing day-after-day. Our on-the-job cross-training provides personal and professional growth.

At National Manufacturing Group, attention to detail isn’t a requirement, and it’s a lifestyle. Our team of craftsmen takes great pride in doing the job right. They take great pride in knowing that because of what they are doing, light rail cars are on track; fire-trucks and medical devices are ready to save lives; planes can land and take-off safely, and school cafeterias have places for students to enjoy lunch.

Please take a moment to meet, and get to know those who make up our locations’ family. We hope you enjoy learning the personal side of those that make National Manufacturing Group an organization that prides themselves on defending our small plant focus, big company resources customer promise.
