Longtime MTD leader returns to guide the company’s next era of innovation and operational excellence in precision micro manufacturing.
CHARLTON, MA — MTD Micro Molding has named John Clark its Chief Executive Officer, effective June 10, 2026. Clark brings more than two decades of expertise in tooling, operations, and high-precision medical manufacturing — and a deep, firsthand understanding of what it takes to reliably produce increasingly complex miniaturized medical components.
Clark first joined MTD in 2008 as a toolmaker and became a key leader during a transformative period of expansion, overseeing the completion of the facility addition that doubled MTD's manufacturing footprint. His return earlier this year — one of several strategic additions to MTD's leadership and technical team — began as Director of Operations before MTD named him CEO. He came back because he believes there's no team in the industry that does what MTD does.
“Customers today are more informed about micro molding than ever,” said Clark, “asking detailed questions about equipment, process discipline, and technical capabilities. What they're looking for is what MTD has been developing for decades. This isn't a new niche for us. We're the ones who defined — and continue to redefine — what this work requires.”
MTD recently optimized what may be the smallest overmold design in its 50-year history — one example of the complex programs the company is taking on. In the first five months of 2026, MTD produced 4 million components across 45 production molds, including tiny orthopedic implants with dead-sharp tips, thin-wall components for minimally invasive procedures, bioresorbable implants, and intricate multi-step overmolded devices. MTD has also reactivated internal lab and testing equipment to advance its materials analysis capabilities, supporting more precise polymer characterization across complex programs.
This reflects a year of deliberate investment in the leadership, technical depth, and operational foundation that make MTD an effective single-source partner for its customers, from concept through validated production. While many manufacturers focus on what's easily producible, MTD starts by understanding why each spec matters.
"By investing ahead of industry needs and developing capabilities before they're required,” said Clark, “we help our customers bring the next generation of medical devices to market with confidence."
"Dennis used to say that what made MTD special was the team's mentality — taking on the projects that start with some element of impossibility and finding a way to conquer them,” said Darlene Tully, Owner of MTD Micro Molding. “John has carried that mentality throughout his career here. He doesn't make promises he can't keep, and he builds teams and processes that deliver on the ones he does. That's the foundation of every customer relationship MTD has, and it's why I trust him to lead this company Ever Forward."
