Transitioning to her operational role meant she would not be working with students directly, but she still managed to build meaningful relationships with them. Every year she would take a group of them  on a tour to her alma in order to encourage them and show them that going to a college or university of their choice was possible no matter their current circumstance. She is very excited to be serving the students and surrounding communities at Caliber!  

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.
