Meet our Administration

Thomas Domer, Principal

Hello Central Middle School Community,

My name is Thomas Domer and I am the Central Middle School Principal. CMS has a reputation for having the best students, teachers, and families in the Bay Area, and I am lucky to be a part of the CMS community.

My goal is to get to know every student personally so that I can best serve the community. I believe that working to develop personal connections is one of the most important aspects in education. I am particularly interested in engaging my efforts in a school with strong commitment to family and community involvement. Working to foster the potential of every student is a particular passion of mine.

I have been working in education for the past 16 years. I began my career at a middle school in San Francisco teaching English and history. I taught high school English in New York City and Burbank, California. I also briefly taught English at Sequoia High School.

More recently, I have been in Pleasanton as a Vice-Principal at a school of nearly 1200 students. There I was charged with curriculum and moving our school to full implementation of the new Common Core Standards. My job was to provide materials that kept teachers up-to-date on best teaching practices, research and programs. I also worked closely with other school administrators on ways to best support our students to meet the challenges of the 21st century.

I look forward to a great year ahead of me getting to know the CMS community. Please stop by my office to say hi whenever you get a chance.

Heidi Mickelsen, Assistant Principal

Hello Central Middle School Families and Community,

My name is Heidi Mickelsen and I am excited to join the staff and students at Central this school year! Most recently I was the assistant principal of a middle school in San Jose, and I am looking forward to being a little closer to home and getting to know the San Carlos community! I am passionate about building a positive school culture, helping students achieve their potential, and encouraging students to integrate academics with their other talents and interests as they progress through middle school.


I started my career in education teaching middle school math and English in Chicago and Boston before returning to the Bay Area where I was born and raised. After taking some time off to be with my three young kids, I worked for a number of years with two educational non-profits supporting low-income elementary and middle school students in East Palo Alto. As I returned to working in school districts, I worked as a math intervention teacher before entering school administration a few years ago. While I love teaching students, I also enjoy the challenge of collaborating with the staff, district, and community to create whole-school change and implement best practices to constantly refine our work as educators. I am also passionate about community service and have been very involved with helping students engage with and serve the broader community in which we live.

Please stop by to introduce yourself when you are on campus - I look forward to meeting you and serving the CMS community!
