Indian Gaming Association honors late Standing Rock Sioux Chairman Ron His Horse Is Thunder

The Indian Gaming Association (IGA) expressed its deep sorrow at the passing of Ron His Horse Is Thunder, former Chairman of the Standing Rock Sioux Tribe and an esteemed leader dedicated to tribal education and advocacy for Native American rights. He passed on March 27, 2025, the association confirmed. 

Ernie Stevens Jr., Chairman of the Indian Gaming Association, said: "Ron was a true Indian Country Warrior and a pillar of strength for our communities. He was a great friend and mentor to me. His tireless work in education and advocacy was instrumental in advancing the rights of Indian Country.

"We have lost a champion for our people, but his legacy will endure in the countless lives he touched and the progress he fought for. Our hearts go out to his family, friends, and all who knew him."

A descendant of Sitting Bull and a member of the Hunkpapa Lakota tribe, Ron's journey began at Standing Rock Community College. He earned his Juris Doctor degree from the University of South Dakota School of Law, which paved the way for him to assume pivotal roles that shaped the educational landscape of tribal colleges.

Throughout his career, Ron served as president of Sitting Bull College, the American Indian College Fund, and Little Hoop Community College, ultimately becoming the Chairman of the Standing Rock Sioux Tribe in 2005. His influential work extended beyond local leadership, as he served as a commissioner for the Higher Learning Commission and as chairman of the President's Board of Advisors on Tribal Colleges and Universities, appointed by President George W. Bush.

In his later years, Ron established a consulting firm with his wife, Deborah, and played a crucial role in stabilizing Little Priest Tribal College in Nebraska. His commitment to community and education was unwavering, reflecting a legacy of service that will be cherished by those he inspired, said the Indian Gaming Association.

Ron was a devoted family man, leaving behind his wife Deborah, and four biological children: Josi Halfred-Mendoza, Ron (aka Little Ron) His Horse Is Thunder, Wiyaka Wastewin His Horse Is Thunder, and Akitcita Cistila His Horse Is Thunder; five grandchildren; and one great-grandchild. 

Burial services will occur on Saturday, April 5th, at the AJ Agard Building, followed by burial at the Messiah Church gravesite in Little Eagle, South Dakota. Service and burial arrangements will be updated as the dates approach.

The Indian Gaming Association extended its heartfelt condolences to the family and friends of Ron His Horse Is Thunder during this challenging time. "His lasting legacy will continue to resonate throughout Indian Country for generations," said IGA.
