Mariah Tanay Ashley

Mariah Ashley is Tsí’naa’jíní (Black Streak Wood People clan), born for Ta’neeszahnii (Tangle People clan). Her maternal grandfather’s clan is Naakai Diné’é (Mexican People) and her paternal grandfather’s clan is Kinyaa'áanii (the Towering House clan). She is from Tsé’chil’tah, New Mexico (just southwest of Gallup). Mariah is an alumni of Northern Arizona University where she received her Bachelor’s degree in Environmental Science and Geology. Her professional experience includes working alongside Indigenous communities, researchers, and organizers in the collective effort to combat climate change in their respective territories and beyond. She’s helped foster projects, facilitate discussions, fundraise, and assist in event coordination throughout the Navajo Nation. She continues to advocate for the health and land of her people on Dinétah.

Her current work at ITEP is under the National Tribal Air Association as the Program Coordinator. Much of her experience has taught her that change is slow moving and ever evolving, celebrating wins and accomplishments is very important, and to always have hope, sihasin. She cares tremendously for her family and all her relations; including Nahasdzáán Níhímá (Mother Earth), and all the plant medicines. She is a creative Indigenous-fem, vegetable-eating, mutt-loving, rock-collecting, outdoor enthusiast who also loves to watch movies and eat hot cheetos.
