AHS Administration

Principal: Megan Barrington

At American High School we strive to help our students achieve in all aspects of their development.  It is my goal that during their time at American High School, every student make progress in their learning, expand their perspectives, and explore new interests.  As we kick off the start of a new school year, I am celebrating five years at American High School and my twentieth year in secondary education.  I feel privileged to work within a community of educators who all value student voices, a respectful population of students with a strong desire to learn, and a network of families and community members who continue to make decisions that are best for students.

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

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!

Assistant Principal: SUMEYYE CARDAKLI

It is with great joy and honor that I join American High School as an assistant principal. While a native of Turkey, I have been living in the Bay Area with my husband and two kids. 

I have been in education as a teacher and leader for twenty years. Throughout my career, I saw how race, ethnicity, gender, language, and socioeconomic status affect students’ education.

I am committed to ensuring the benefits of public education extend to all students. I plan to pursue this work by informing, influencing, and inspiring stakeholders while maintaining a focus on inclusion and equity in all aspects of our interactions with students on a day to day basis.

I am looking forward to collaborating for our students’ success!

Go Eagles!

I am excited and proud to be a part of the American High School staff and community as an Assistant Principal. It is an honor to be part of such a diverse and inclusive community that values equity, academic excellence, and supporting our students in their learning and social-emotional wellbeing. The school's vision of helping students take ownership of their own learning and preparing them to be productive members of society that respect all people of diverse communities align with my own core values. When I became a teacher, I understood how creating positive relationships with students can help them to not only succeed academically, but to improve their wellbeing in a safe learning environment as well. As an administrator, my goal is to continue to build a positive school culture through my daily interactions with the staff and students. My hope for this school year is to continue our work in creating a warm, and inclusive learning environment where all students feel supported.
