ÜBER DIESE EPISODE
Walking Shield has spent nearly four decades improving quality of life for Native communities across the United States—bridging sovereign tribal nations with philanthropy, federal agencies, and the U.S. military. Alongside the Walking Shield team, Executive Director, Dr. John Castillo, and Senior Fellow, Mariano Diaz help tribes build the capacity needed to secure federal funding, strengthen infrastructure, and advance true self-determination. Their work blends grassroots trust-building with systems-level strategy, supporting tribes on projects ranging from road repairs and water access to energy development, environmental co-management, and leadership planning.
This Episode:
What does true collaboration with tribal nations require?
Dr. John Castillo and Mariano Diaz highlight the deep assets that guide Native communities, including long-standing governance traditions, cultural and environmental knowledge, and a strong commitment to collective well-being. They share how Walking Shield helps tribes use these strengths to access federal resources, plan for long-term development, and steward land and water. They also discuss the systemic barriers tribes still face, such as underinvestment and complex federal requirements, and how capacity-building can make a meaningful difference.
Together with Grant, they explore San Diego’s uniquely rich tribal landscape, the growing promise of co-management of natural resources, and why trust, relationship-building, and listening first are essential for any partnership with Indian Country. At its heart, the conversation offers a long view of resilience and strategy, reminding us that when Native leadership is honored and communities have the tools to act on their priorities, progress becomes both possible and lasting.
