Greg McArthur’s journey in manufacturing began as a child sweeping floors and cleaning mats in his father’s machine shop. Over the years, he gained hands-on experience, evolving from a lathe hand to a skilled CNC machinist, estimator, and engineer. Eventually, Greg took a bold leap, bidding on a machine sight unseen on eBay and figuring out how to transport and operate it—foreshadowing his entrepreneurial spirit.

In 2017, Greg founded NTL Industries in his garage while working a full-time job. By carefully building a financial foundation, he transitioned to renting a facility, leasing machines, and growing a team. 

Today, NTL Industries is a full-service CNC precision machining shop in Sterling Heights, MI, specializing in defense, aerospace, agriculture, and automation. The company has grown to 11 employees and is moving into a state-of-the-art, 13,000-square-foot facility that reflects its ambitious trajectory.

From the beginning, Greg recognized the power of social media as a cornerstone of NTL’s growth. He embraced platforms like LinkedIn to build a following, share exceptional work, and attract new clients. Greg’s mantra is clear: if you’re not promoting yourself every day, you’re missing opportunities. By leveraging social media as a free marketing tool, NTL has gained exposure, received RFQs, and established a reputation for excellence.

In this episode, Greg shares his story, insights on growing a machine shop, and advice for young entrepreneurs in manufacturing. Whether it’s navigating an economic downturn, diversifying into new markets, or overcoming challenges like labor shortages, Greg’s practical wisdom is a must-hear for anyone looking to grow their business.
