Transitioning to her operational role meant she would not be working with students directly, but she still managed to build meaningful relationships with them.

Estefania Garcia, SSO Administrative Assistant
I was born in Ecuador and raised in Oakland. I earned my degree in Legal Studies from UC Berkeley. After I graduated college, I worked at Kaiser Permanente's Human Resources Department for their Benefits and Enrollments team. While doing this work, I was also able to learn a lot about Human Resources and how to better assist employees regarding both benefit and leave concerns. However, my passion has always been to work in a place where I could give back to a community like my own. While in college, I volunteered at my elementary school as well as at a Head Start located in Oakland and found that I could do meaningful work outside of the classroom. Through these volunteer experiences, I realized that there was a lot of work to do for the families in my community; this is where a passion to aid in this work began. During my last years of UC Berkeley, I expanded this mission by volunteering at a non-profit Immigration center located in Berkeley. I am thrilled to have found my way back to serving communities that mirror the one I grew up in as the SSO Administrative Assistant at Caliber Schools.
