Assistant Principal: Jason Cain

Administrator for Grade 9:

Education values the growth of the entire student, focusing on academics as well as necessary skills to be successful.  School is a place for students to be challenged as well as supported throughout their adolescence.  It is an environment that allows students an opportunity to explore, make connections, and relate to the world and their communities.  I am a product of FUSD and have the opportunity to work in this district my entire career as a teacher, program manager, and administrator. I believe in the values of this District and support the decisions made around student growth and mindset.  FUSD supports student diversity and their achievements.  The District’s focus is student-centered that incorporates 21st Century Learning to best support all students in their education.  The American High School Community supports their students and challenges them with a rigorous education that allows them to be successful after high school.  This community helps one another grow as an individual and as a group because it understands the value in working together to grow as one.  In my first year at American, I’ve been graciously welcomed by the community and feel fortunate to be part of this attendance area.


Assistant Principal: LISA DIACONIS

Administrator for Grade 11:

Welcome to American High School!  I am excited to continue serving students, staff, parents and the AHS community as Assistant Principal.  I began my career in Fremont Unified School District in 2010, where I taught for 8 years as a high school English teacher at Robertson High School.  The following summer I served as Principal for Fremont Unified’s Summer Success Academy, for incoming 7th and 8th graders. Then, at the beginning of the 2018-19 school year, I had the opportunity to join the American High School administrative team, where I currently work with 11th grade students (class of 2021). 

I earned my B.A. in English Literature from San Francisco State University, my Single Subject Teaching Credential and M.A. in Education from the University of California, Davis, and my Administrative Credential from Saint Mary’s College.  Ultimately, I went into education to not only build students’ academic skills, but to also build their belief in themselves. Additionally, I believe that all students can learn, and deserve to have a school environment in which they feel safe, welcome, and have positive relationships with staff.      

I look forward to a successful school year at American High School, and am excited to continue supporting and getting to know students, staff, parents, and the AHS community. Go Eagles!

I became a teacher and then an administrator because I wanted to give back to the community. As a student, I had teachers who treated us with dignity, as individuals, and who challenged us to think through problems, both critically and creatively. These teachers provided the freedom for us to make mistakes and to learn from them. These are the qualities I wanted to emulate and perfect - treating young adults with dignity and respect, accepting their own uniqueness, and challenging them to think broadly, to make their world a better place. I still continue to make mistakes, and encourage my own students to make mistakes as well - to learn from them and to be better people as a result.

Assistant Principal: Jennifer Watson-Bird

Administrator for Grade 10

I am extremely grateful and humble to be given the opportunity to be part of the American High community and continue working with these awesome young adults as they navigate their way to graduation and beyond. 

As many of you know, I am currently an Assistant Principal at Thornton Jr High and have held that position since the 2016-2017 school year. Prior to that, I taught English there since 1998-1999 and was a student there from 1980-1982.

I find my unique half-time American, half-time Thornton position particularly rewarding because it enables me to continue nurturing the relationships I've worked hard to build with students while at Thornton. 

My goal when interacting with students is to act and speak to them in a way I would want someone to act and speak to my own kids while they are at school. I use restorative conversations whenever possible and try to help them understand empathy and where and when certain behaviors and actions are appropriate. 

Please feel free to reach out to me if there is anything I can do to help bridge the connection between home and school.
