Dominic Cardea (Dom) recently retired after a 34 year National Park Service career spent turning big ideas—geology, history, culture, and community—into invitations to be curious. He helped shape and facilitate national interpretation and leadership programs, coached frontline interpreters, and trained hundreds in digital interpretation. A curious philosopher at heart, Dom loves the “why” behind a place and its objects—what they reveal, how they connect, and the questions they spark. He champions audience-centered, resource-focused interpretation that’s collaborative and co-creative, not a TED Talk in the woods. He’s happiest when the guests, places and objects becomes the co-facilitators of experiences—and everyone leaves wanting to explore more- including him .

Tim Merriman and Bill Gwaltney talk story with Daniel Martinez on Reflections on Interpretation. For historian Daniel Martinez, history isn’t just something to study—it’s something you feel. After 44 years with the National Park Service, most recently as historian at the Pearl Harbor National Memorial, Martinez reflects on a career dedicated to keeping the past vividly alive.

From his own family’s memories of December 7, 1941 to his years connecting with survivors, leaders, and visitors, Martinez has helped countless people see the human side of history—and feel its lasting presence.

He shares the stories, moments, and relationships that shaped his life’s work from his start at Little Bighorn Battlefield National Monument to Pearl Harbor and why the lessons of war, peace, and resilience still matter today.

Gary Candelaria brings a lifetime of dedication to America’s public lands to this episode of Reflections on Interpretation: Talking Story with Guides and Interpreters. Raised in Los Angeles and inspired early on to become a park ranger, he pursued that dream through a forestry degree at Oregon State University before entering the prestigious Intake Ranger program in 1975. His first assignment at Saratoga National Historical Park during the nation’s Bicentennial set the stage for a distinguished National Park Service career.

Candelaria went on to serve in key leadership roles across the country, Assistant Chief of Interpretation at Ozark National Scenic Riverways, Chief Ranger at Sitka National Historical Park, and Superintendent at Fort Laramie National Historic Site, Pinnacles (then National Monument), and Wrangell–St. Elias National Park & Preserve. Along the way he earned a master’s degree from the University of Oklahoma and worked in Washington, D.C., as assistant to Director Roger Kennedy.

Before retiring in 2008, Candelaria capped his service as Assistant Director of Harpers Ferry Center and Associate Regional Director for Cultural Resources in Omaha. Now living in Sharpsburg, Maryland, he continues contributing to historical scholarship as a contractor for the U.S. Navy, updating the Dictionary of American Naval Fighting Ships.

Join Bill Gwaltney and Tim Merriman as Gary reflects on a remarkable career shaped by curiosity, stewardship, and a deep commitment to interpretation.

Join Tim Merriman and Bill Gwaltney for a fascinating conversation with T. Lindsay Baker, a historian of the American West who doesn’t just write about the past, he’s lived it.

Author of more than two dozen peer-reviewed histories and a lifelong interpreter, Baker brings academic rigor and interpretive insight together in ways few others do. Known for using first-person interpretive scenarios in his university classrooms and immersive living history to inform his writing, Lindsay once built and lived in a sod house on the Great Plains for 18 months, just to better understand frontier life.

T. Lindsay shows how deep empathy and lived experience can change how we teach, write, and guide at the intersections of history, storytelling, and self-awareness. Whether you’re a museum educator, park interpreter, or heritage trainer, this episode will challenge and inspire you to think differently about how and why we interpret.

He's also a Fulbright Scholar and Texas Tech alum who held curatorial and faculty roles at major institutions across Texas and beyond. But we think you’ll appreciate him most for his humility, humor, and the way he helps us see interpretation as a tool for deep connection.

For more than fifty years, I’ve been asking one question: What is the purpose of heritage interpretation? Early in my career, a few key experiences set me on a path of reflection—a path that has shaped every step of my professional life since.

Few of us have the luxury of working in isolation or for ourselves alone. If interpretation is to be meaningful and sustainable, it must do more than entertain or inform. We have to protect the resource itself and nurture the circumstances that make interpretation possible. That means building purpose—real, intentional purpose—into everything we plan and do.

I’m Tim Merriman, and in this week’s episode of Reflections on Interpretation, I share a story from my early years—one that forever changed how I think about purpose in our work. It began with a simple question from another trainer: Why did purpose become so important to you so early on?

Join me for this short, heartfelt episode. I hope it inspires you to think about how your work supports the mission and purpose of your organization—and why that purpose matters to you.
