Massachusetts’ Diversified Machining Company Is Scaling Up for Growth

Rebuilding a Successful Company to be a Bigger One


Hudson, MA–November 4, 2022–Phil Holman joined Diversified Machining after a successful 36-year career as owner and president of Fourstar Connections, a cable assemblies contract manufacturing company in Hudson, MA.

Downshifting from a larger scale operation, coming from a complementary industry, Holman knew his work was cut out for him when he sold his company and invested in Diversified Machining with existing owner, Chet MacDonald. MacDonald has been running Diversified Machining for almost four decades, and though at a smaller scale, has been running his shop with the same focus that Fourstar did: expert in his field of machining, quality- and customer-centric, relationship-strong, very personal, one-on-one collaboration, helping people with design for manufacturability (DFM) requirements and new production introduction (NPI), with on-time delivery.


Holman contracted Diversified Machining countless times to build machined parts for Fourstar’s cable assemblies. Having worked for manyDiversified Machining _TRAK years with MacDonald, Holman recognized the efficient business model of Diversified and understood where and how to grow its machining business—and not just in capital expenditures on the new equipment they added to the facility. In a recent article, Holman discusses the steps they made to scale up Diversified to keep the same level of service, while increasing its—and customers’—capacity for machined parts. This article addresses:


  • Technology
  • ISO certification
  • Marketing
  • Legacy knowledge
  • Industries served

As Holman says, “I needed to explore the business model priorities I had been operating from for almost four decades and shift them to more of a start-up mentality. Probably the most crucial piece of this pie was in recognizing the depth and breadth of networks and resources we had built at Fourstar: everything from our talented staff, affiliate relationships with suppliers and vendors, real-time, digital technologies, documented processes and procedures, ISO certification, etc. Chet had all the foundations in place when I came on board—and was running a fine business with satisfied customers—but did not have the tools in place to scale up. We are solid and ready to bring on more customers and welcome new inquiries.”
