Principal's Greeting

Welcome to the ACS Athens Academy!

I am genuinely excited and honored to welcome our students, families, teachers, and staff as we kick off the 2025-26 school year.

At the Academy, we cherish a long-standing tradition that emphasizes academic excellence while continually striving to improve and meet the diverse needs of our students. I am dedicated to collaborating with everyone to ensure that all students have a meaningful and enriching high school experience, laying a strong foundation for their future success in college and beyond. My goal is to foster qualities such as self-advocacy, curiosity, compassion, and integrity in our students, empowering them to make a positive impact on society. I look forward to working with our students, teachers, and staff as they explore, discover, and reach their full potential.

My career in education began over 35 years ago in New York City as a Social Studies teacher, and I have spent the past 20 years as a high school principal. I am eager to bring my experience and passion for learning to ACS Athens. This journey feels especially meaningful as I return to Greece, the homeland of my heritage, alongside my wife, Kristy, and our two beloved mini-huskies, Hudson and Nooma.

I am excited to be part of the ACS Athens community and to work with our outstanding faculty and staff as we start this new school year. I look forward to meeting each of you and partnering together to make this year a great success.
