As America’s 250th Anniversary approaches, one theme keeps rising to the top: leadership.

Many of you have been asking for a speaker who can bring this milestone to life in a way that feels meaningful and relevant for today. That is exactly why we are excited to feature Marc Koehler and his keynote, 250 Years of Leadership. One Mission: Perform Under Pressure.

Marc offers a perspective most audiences have never seen. As a former U.S. Navy Nuclear Submarine Officer, he takes you beneath the surface into a world where hesitation is not an option, uncertainty is constant, and every decision counts. Leading more than 100 sailors on high stakes missions, he knows what it truly takes to perform under pressure.

What makes this keynote stand out is how it connects the past to the present. From America’s first submarine in 1776 to today’s Silent Service, Marc brings 250 years of leadership to life in a way that feels both powerful and incredibly relevant for leaders navigating today’s challenges.

“250 Years of Leadership. One Mission: Perform Under Pressure.”

As the United States marks its 250th anniversary, we reflect not only on the leaders who shaped our nation above the surface—but also those who operated in silence beneath it, safeguarding freedom in the most unforgiving environments on earth.  Former U.S. Navy Nuclear Submarine Officer and leadership expert Marc Koehler takes audiences deep below the ocean’s surface—into the high-stakes world of a nuclear submarine, where every decision carries consequence, uncertainty is constant, and failure is not an option. Drawing on his experience leading over 100 sailors aboard a nuclear submarine on missions critical to national security, Marc reveals how leadership under pressure has quietly protected and propelled our nation for decades.

From the first US Submarine “The Turtle” (developed in 1776) that launched America, to the unseen missions of the Silent Service that defend it today, this keynote bridges 250 years of leadership evolution. Marc introduces his Fast Attack Leadership™ framework—a battle-tested system forged over 250 years in the depths of the ocean—to show how leaders can align teams to mission, make decisions in ambiguity, communicate with precision, and perform at the highest level under sustained pressure.

At a time when disruption is constant and the stakes feel higher than ever, this presentation delivers a powerful message:  The same principles that have safeguarded our nation for 250 years can equip today’s leaders to navigate the future.

Audiences will leave inspired and equipped to:

  • Lead with clarity and purpose in uncertain environments
  • Build high-performance cultures grounded in trust, accountability, and teamwork
  • Make faster, better decisions when the pressure is on
  • Communicate with precision to drive alignment and execution
  • Rise to the moment—because leadership isn’t about rank… it’s about responsibility

Marc Koehler connects 250 years of leadership legacy to what leaders face right now, showing that while the world changes, great leadership does not. Even better, audiences walk away with practical ideas they can use immediately. This keynote leaves people thinking differently about leadership. It is not about title. It is about action. It is about stepping up when it matters most and being ready to perform under pressure. If you are planning a 250th anniversary event and want something meaningful, engaging, and relevant, Marc Koehler delivers a perspective that truly stands apart.
