Meet Our Team

We are creating a strong foundation with a diverse team of professionals driving our mission forward. Having individuals from different backgrounds and experiences will bring unique perspectives and approaches to addressing challenges and achieving our goals. By prioritizing diversity and recognizing the importance of representation at every stage of womanhood, the organization is ensuring that its initiatives resonate deeply with the community it serves. The collective dedication and passion for empowering matrilineal leadership will ensure that The 100 Horses Women's Society remains a beacon of hope and support for girls and women from all four stages of womanhood. Together, they embody the spirit of unity and resilience, standing as the backbone of the organization's efforts to create a more equitable and inclusive world for girls and women within our Cheyenne River Tribal Communities.

Medina Matonis

100 Horses Society Member

100 Horses Women’s Society Executive Director

Han mitakuyepi, Sahuwin emaciyapi. I am an enrolled member of the Cheyenne River Sioux Tribe and grew up in the community of Red Scaffold. I went through Isnati Ca Lowanpi in 2016 alongside my two daughters with my Ina, Rosalita Roach(my mother and cofounder of the 100 Horses Society), as our sponsor. I am ina to three awesome children, proud wife of a Navy Veteran, unci to two very special takoja girls, and tunwin to many amazing youth. I am very passionate about our youth. In 2016 the youth at Dupree School asked for a space to learn and practice their culture, in turn I founded the after school Lakota club, and have been bringing Lakota cultural education to the students since. My daughters and I are very active in supporting the mission of the 100 Horses Society, ensuring the Becoming a Woman ceremony is available to the future generation of girls and women of all ages. Tunwin Sandy and Ina Rosie gifted me with a leadership role for the Society. Creator puts you where you are supposed to be and has led me on a path of supporting and serving our youth. You are never where you are, by mistake, there is a purpose and one must be open to receive the message. My 150 year goal is to help create culturally rooted mothers, sisters, aunts, and grandmothers that lead their youth to success.

100 Horses Women’s Society Youth Mentor

Han Mitakuyapi, Eunice Guardipee, emaciyapi. I am Mnicoujou and Hunkpapa Lakota and an enrolled member of the Cheyenne River Sioux Tribe. My ina is Georgia Guardipee (Hunkpapa Lakota) and my até is Alan Guardipee (Mnicoujou Lakota). I was raised by my unci, Edith Larrabee (Mnicoujou Lakota). I grew up in Bear Creek, Swift Bird, Rapid City, and Eagle Butte. I spent a lot of my childhood on the powwow trail with my tunwin Luanne and big sister/cousin MerriAllyn. My tunwin Luanne made all my regalia for me. I was Mini Miss Cheyenne River at age 7, so tunwin made sure that I attended powwows all over Turtle Island. We were a powwow family. I enjoy taking my daughters, Xena James and Arabella James to powwows. They both dance jingle, I taught them at a young age that jingle is a healing dance. I was raised in the church, so I am reconnecting with my Lakota culture. I’m passionate about learning our ways so that I can teach my two daughters and the youth in our communities. This will help so they can teach their children, grandchildren, so on and so forth. I’m currently attending Oglala Lakota College part-time for Lakota Studies. I’m thankful for this job with the 100 Horses Women’s Society as I’ve been learning a lot since I’ve started. Thanks to Medina and Tami for all the knowledge they’ve been sharing. It’s been amazing to watch this all unfold so far, and I feel empowered to be a part of it. I’m excited to see the progress throughout the years.
