Our Team

We are a collective of health professionals, artists, researchers, and consultants working at the intersection of feminism, anti-racism, and trauma-responsiveness. Collaborating with others, we strive to dismantle white-supremacist, heteropatriarchal, cisnormative, mono-normative, and colonial practices within education, healthcare, research, and the broader community. Inspired by BIPOC scholars, feminists, freedom fighters, community organizers, and abolitionists, we are dedicated to supporting transformative and healing justice efforts.
