What does a life of curiosity, service, and lasting impact truly look like?

In this episode of Origin Impact Podcast, host Brad Kelly sits down with legendary teacher and Yellowstone National Park ranger Harlan Kredit. At 86 years old, Harlan is still actively teaching, mentoring students, and preparing for his 54th summer in Yellowstone—living proof that purpose doesn’t retire.

Harlan shares unforgettable stories from a lifetime of exploration and service, including witnessing the historic 1988 Yellowstone fires, helping restore salmon runs in his hometown creek, and working closely with wolves, bears, and bison inside America’s first national park. With over six decades in education, he reflects on the lessons that have shaped generations of students.

This conversation goes beyond stories—diving into the science of ecosystems, from salmon migration to wolf reintroduction and forest fire recovery—while uncovering deeper insights about leadership, curiosity, and living a meaningful life.

Harlan also challenges conventional thinking about retirement, shares his philosophy on staying engaged at any age, and even entertains the possibility of Bigfoot.

If you’re seeking wisdom on purpose, nature, leadership, and how to make a lasting impact, this episode is for you.

Your life matters. Make an impact today—no matter how small.
