Natalie Morosi, Founder and Executive Director

Dr. Natalie Morosi has spent her career as a teacher and school leader in bilingual educational settings, first as a classroom teacher for nine years in a traditional public school in Nashville, and later as the founding Lower School Director of a small independent American school in Madrid. Natalie holds a BS from Furman University in Psychology and Spanish, an MAT from Belmont University, and an Ed.D from Vanderbilt University in K-12 Education Leadership and Policy. Natalie’s graduate and professional work have focused on the academic, social, and cultural benefits of bilingual education, as well as drivers of school choice within educational systems.


Natalie has engaged in conversations with families and educators for over a decade about the need for an intentionally diverse bilingual school option for Nashville's growing and increasingly multicultural population. She is grateful for the opportunity to develop and launch Aventura Community School  through the Diverse Charter Schools Coalition's UnifiED School Launch Fellowship. Natalie's two children are future Aventura students!
