    Time with the company: 45 Years

    “I started First Company when I was a young, single guy. As the years went on, I saw how great it was to work for the Nation family and First Company. The company has provided me with the knowledge and skills to be a Journeyman Tool & Die Maker. Through my 45 years at First Co., it has been a good stable company for me to raise and support my family. I look forward to helping the company grow and continue to be successful.”
