Medina Matonis
100 Horses Society Member
100 Horses Women’s Society Executive Director
Han mitakuyepi, Hunska Luta Win 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.

Hello relatives, My name is Eunice Guardipee. I am Mnicoujou and Hunkpapa Lakota. An enrolled member of the Cheyenne River Sioux Tribe and I currently reside on the Cheyenne River Sioux Tribe Reservation in Bear Creek. My mother is Georgia Baker (Hunkpapa Lakota) and my father is Alan Guardipee (Mnicoujou Lakota). My grandparents on my maternal side are Lucille Howard and Cecil Baker Sr. I was raised by my paternal Grandmother Edith Eye. 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 have 3 children; Two daughters, Xena and Arabella who are now 9 and 8, and I just recently had my son, Tokala. I enjoy taking them to powwows. My daughters both dance jingle dress, I taught them at a young age that jingle dress dancing is a healing dance. I was raised in the church and now I am reconnecting with my Lakota culture. I’m passionate about learning our Lakota lifeways so that I can teach my children and the youth in our communities. Working with the 100 Horses Women’s Society has been a beautiful experience, I’m so grateful to be in the role of a Youth Mentor. I have learned a lot since I’ve started and have built meaningful relationships with so many amazing wincincila and winyan along the way. Thanks to my mentors that I’ve met along the way for all the knowledge and teachings. It has been amazing to watch this all unfold so far, and I feel empowered to be a part of it and honored to mentor the youth and help carry knowledge forward to strengthen the generations to come. I’m excited to be a part of the progress throughout the years.
Hochokanwin"Cho" Chasing Hawk
100 Horses Women’s Society Youth Mentor
Han MiTakuyapi, Hocokanwin Chasing Hawk emaciyapi, I also go by Cho for short. Throughout my childhood and teenage years, I’ve moved around a lot between YST, CRST, SRST, and Bismarck, ND. I am Itazipco Lakota and Pabaksa Dakota. I am an enrolled member of the Cheyenne River Sioux Tribe along with my father, Wiyaka Chasing Hawk and my mother who raised me, Michele Chasing Hawk. My birth mother is Neva White Shield from the Spirit Lake Tribe. My paternal grandparents are Mabel Ann Eagle Hunter and Eagle Hunter, who are also enrolled members of Cheyenne River. During my time attending school in Dupree, my sister, DeCora Hawk, introduced me to handgames, where I also met Medina. What was meant to be a one-time tournament turned into something much more—I enjoyed handgames so much that I decided to stay and join the team for the next three years, up until the pandemic. Afterward, I moved to Bismarck, where I graduated from Bismarck High School in 2024. Although I have faced some setbacks over the past couple of years, I remain determined to continue pursuing my educational goals. I moved back to Cheyenne River in 2025, at the beginning of summer and joined the 100 Horses Women’s Society at the end of the summer! I enjoy being a youth mentor and working alongside Medina, Eunice, and Zaniya. I’m grateful for the positive work environment we have! I’ve been learning a lot since joining and I love learning more about our culture. Every day is something new and it's been nothing but good times! I enjoy meeting different people and getting to know the communities. I’m happy to be of service to the communities and I can’t wait to see the future of this program!
