Melissa Mercado

Cesar E.Chavez Leadership Academy

Mentor

Yá'át'ééh! My name is Melissa Mercado and I am an Indigenous matriarch from the Diné (Navajo) Nation. I am a proud Arizona State University alumni, graduating with a degree in Elementary Education with an emphasis in Bilingual Education. Currently, I am at the end of my third year teaching at Cesar E.Chavez Leadership Academy in South Phoenix, Arizona, where I teach science to fifth and sixth graders. In the last seven years, I have had the opportunity to participate in various organizations that allowed me to present my experiences and knowledge at numerous local and national conferences, giving a voice to indigenous voices. As an indigenous person, I am constantly working to decolonize my way of life and advocate and create opportunities for indigenous youth to reclaim and sustain language and culture. For this reason, during the summer I host a day camp to provide space and learning for Diné kids to connect to their culture, language, and other kids. I find joy in dancing salsa, bachata, cha cha cha, and merengue, spending time with my siblings and family, learning Spanish and human anatomy and physiology, crafting, and sewing.

Previously, I taught 6th grade and this will be my fourth year teaching 4th grade. I am an enrolled member of the Chemehuevi Indian Tribe: we are the southernmost branch of Souther Paiute.  I’m from a small town alongside the Colorado River called Parker, Arizona. I moved to the valley over a decade ago to attend Arizona State University, and then Grand Canyon University. I earned both my bachelor’s and master’s degrees at Grand Canyon University. I am an active member of my school community and continue to seek opportunities to perfect my teaching craft and support my diverse learners. I am also a proud member of the Arizona Geographic Alliance. I was a part of the 2020 STEMSS Cohort and then became a Teacher Lead in the Summer of 2021. I am extremely passionate about multicultural education and representation in the classroom!
