Nayasia Coleman

Development Coordinator

Americorps VISTA

Nayasia Coleman is a Black, Queer, activist, healer, and creator that holds a Bachelor of Science in Writing and Gender and Women Studies from Kennesaw State University. Her life research question lies in what her ancestors believed prior to colonization specifically looking at spirituality, identity, relationships, and education. She is heavily influenced by her Yoruban belief system, her background in Queer Theory, and Afro-futurism.

While at her alma mater, she was a part of the team to establish an on-campus LGBTQ resource center, one of few in the South, that continues to serve as a safe haven for students. She was also nominated as the Co-chair of the Presidential Commission on LGBTQ Initiatives. During her tenure in that position she was pivotal to the policy shifts to include student’s preferred pronouns on student IDs, create more LGBTQ representation in on-campus speakers, and achieve a successful consolidation with Southern Polytechnic University.

Now based in the California Bay Area, Nayasia serves as the Development Coordinator for IGP and loves the way this position creates connections that lead to more resources to do this transformative work. As an AmeriCorps Vista member she has dedicated her life to the members of our community that are most often forgotten.

Sharing her varied degree of knowledge, Nayasia has presented at Kennesaw State University’s Summit on Civil & Human Rights, Southern Fried Queer Pride, Sex Down South, and will be at South West Love Fest this April in Tucson, Arizona as well as Black Poly Pride in Washington, D.C. this upcoming summer.
