When I think about inspiring stories of resilience and vision in the world of manufacturing, Sam Thevanayagam’s journey is one that stands out. In this episode of Machine Shop Mastery, I sit down with Sam, the founder of Parts Life Inc. and the leader behind Deval Lifecycle, to unpack his incredible path from Sri Lanka to Philadelphia, from downsizing his home to fund his dream, to acquiring a bankrupt business and transforming it into a thriving, mission-driven company employing nearly 200 people.

What struck me most about Sam is not just his sharp business acumen or the bold risks he’s taken—it’s the way he flips the traditional narrative. Instead of using people to build a business, he uses his business to build people. From brewing oatmeal for his team to helping nearly 30 employees buy their first homes, Sam has built a culture of empowerment, grace, and second chances. His deep belief in redemption and workforce development has shaped his companies into places where lives are transformed as much as parts.

We also dive into the strategic side of running a high-mix, low-volume shop that supports the defense industry. Sam shares how he navigated workforce shortages by launching his own in-house machining institute, how he invests in quality through systems and prevention, and why he believes visibility and trust with customers are just as important as making parts.

This episode is packed with lessons about leadership, perseverance, and what it means to align a business with purpose. Whether you’re running a small shop or scaling a growing organization, Sam’s story will leave you thinking differently about the role of a manufacturer in today’s world.
