Our Team


Ava Bailey-Klugh

Development and Communications Intern

My name is Ava Bailey-Klugh (she/her). I am 19 and currently an English and Women and Gender Studies double major. I identify as a lesbian and I am Jarocho. I am from a small fishing town in Veracruz. My life goals include finding what makes me happy and living every moment to the fullest. I hope to one day become a teacher of some sort and have a full circle moment by teaching at the schools I grew up going to. 

I’ve always had an interest in doing anything to help my community. I’ve done some work in my classes at college to raise awareness for LGBTQIA+ student struggles and visibility on campus and hope to continue supporting my community. In my free time I love writing poetry, going for long drives, taking long walks in nature and blasting music by Montellfish.
