Our Team

We are a group of health professionals, artists, researchers, and consultants who aim to exist at the intersection of feminism, anti-racism, and trauma-responsiveness. We are working with others to dismantle white-supremacist, heteropatriarchal, cisnormative, mono-normative, and colonial practices as they exist within the classroom, healthcare system, research lab, and larger community. We are inspired by BIPOC scholars, feminists, freedom fighters, community organizers, and abolitionists. Grounded in their teachings, our aim is to support transformative justice and healing justice efforts.
