Niki Martinez is a leading social justice advocate and organizer dedicated to ending mass incarceration and dismantling systemic injustices and the criminalization of women, gender expansive and trans people. Since her release in 2019, she has mentored countless individuals, been a leader in the Credible Messenger movement, while also working on key propositions and policies and continuing to advocate for folks inside of the women’s facilities. Currently, Niki serves as the Administrative and Organizing Director of Sister Warriors Freedom Coalition and continues to build Sister Warriors Chapters throughout the state, providing spaces for community love, political consciousness and power. While incarcerated, she co-founded a youth-centered advocacy organization and holds certifications in trauma-informed care, relapse prevention, and restorative justice.
