Faculty & Staff

All faculty members are credentialed.


Lizbeth Caraballo 
K-2nd Grade
Hello, my name is Lizbeth Caraballo and I am originally from the beautiful island of Puerto Rico. I am 4th generation Seventh-day Adventist and am so excited to join San Francisco Adventist School this school year. This will be my 11th year of teaching in the Adventist educational system. I have my Bachelor's degree from Columbia Union College now known as "Washington Adventist University" and my Master's from La Sierra University.
It is my hope and goal for all my students that they are successful and are able to realize their full potential. There is material that you must know to prepare you for high school; there are also things I want to guide you through to prepare you for life.
The most important thing in this world is having a real, functional and true relationship with Christ. When He parts the clouds upon His return, He is not looking for those on the Deans list, He will come for those who know and love Him.
I want to have fun this year implementing the new technology we have available here at SFAS. It is my goal and desire to create the best learning environment we can so students can enjoy the process of growing up Godly.
Betty Hsue
3rd-5th Grade Teacher
Many of you might be familiar with Betty Hsue; she’s not a stranger to our campus. She taught here for more than 19 years, when she retired to help care for her father who had cancer. Over the years since her retirement she has frequently volunteered at our school both in long term and short term teaching positions, and she continues to hold a valid California teaching credential.  After many years teaching in both the private and public school arena she currently substitutes for our school and she is a blessing we do not deserve but so overwhelmingly appreciate.

Melody Trauthwein
6th-8th Grade Teacher
My name is Melody Trauthwein and I am delighted to be starting my second year teaching at SFAS. Although I spent eleven years teaching music, math and science in Maryland, this is my home.  I attended Pleasant Hill Junior Academy and graduated from Rio Lindo Academy.  I received my Bachelor’s Degree from Pacific Union College and my Master’s Degree from the University of Oregon.  I have been a teacher in Seventh-day Adventist schools for 17 years.  My philosophy of teaching is that everyone can learn and learn well.  I believe that determination and hard work are much more important to success than is talent.  I believe that God will give us the ability to do whatever He asks of us.  I heard someone say this and I share it with my students: God doesn’t call the equipped, He equips the called.
