Estefania was born in Ecuador and raised in Oakland. She earned her degree in Legal Studies from UC Berkeley in 2017. After graduating college, she worked at Kaiser Permanente's Human Resources Department for their Benefits and Enrollments team. While doing this work, she was also able to learn a lot about Human Resources and how to better assist employees regarding both benefit and leave concerns. However, she found that she was not living her passion, which has always been to work in a place where she could give back to a community like her own. While in college she volunteered at her elementary school as well as at a Head Start located in Oakland and found that she could do meaningful work outside of the classroom. Through these volunteer experiences, she realized that there was a lot of work to do be done for the families in our community; this is where a passion to aid in this work began. During her last years of UC Berkeley, she expanded this mission by volunteering at a non-profit Immigration center located in Berkeley. She is thrilled to have found her way back to serving communities that mirror the one she grew up in as the SSO Administrative Assistant at Caliber Schools.
