Mr. Mark Brummer

Mark Brummer is a visionary CEO, principal negotiator, and developer working at the forefront of infrastructure, finance, and transformative industry. A reputation built on delivery, Mark leads from the front — whether he’s securing multi-million-dollar deals in the DRC’s mining sector, launching international cargo airports across two nations, or engineering next-generation energy and research systems, including an advanced high-capacity oil refinery.

With decades of experience and an instinct for both innovation and strategy, Mark is known for building on what others only talk about. His leadership blends the precision of a developer, the foresight of a strategist, and the unwavering commitment of someone who gets personally involved from blueprint to execution.

Driven equally by the challenge of the build and the legacy it leaves behind, Mark has become a relentless force for progress. His guiding principle —

“Experience is experience; however, it’s earned. I never lose – I win, or I learn.” captures a mindset rooted in action, accountability, and adaptability.
Mark is building more than projects. He’s building a Can-do culture: a framework of relentless execution, bold vision, and enduring results.
Get up. Show up. Deliver.

That’s not a motto — it’s how he leads.
