Ms. Bernabe

Welcome!

I look forward to an exciting and fun school year! This year, I'll be teaching Algebra I and Precalculus. You will find helpful information and links on this page so visit often. If you have any questions, please email me. 

 

A little bit about me.

 

I earned my Bachelor of Science degree in Astrophysics (Physics Concentration in Astronomy) at San Francisco State University and my teaching credential in math and science at Notre Dame de Namur University. This is my eight year at South San Francisco Unified School District: six years as a math teacher at Parkway Heights Middle School and now at El Camino High School. Prior to teaching in this district, I worked as a physics and math teacher at Mercy High School in Burlingame. 

 

If I'm not working, I'm likely spending time with friends and family, playing the guitar, singing, exploring the natural world and being involved in the community.
