Christina Tettonis

Superintendent of Schools

Christina Tettonis is the Superintendent of The Hellenic Classical Charter Schools (HCCS), among New York City?s highest-performing public charter schools serving students from Pre-K through Grade 8.

She previously served as Principal of HCCS?s founding school in Park Slope, Brooklyn from 2007 to 2019. During her tenure, she successfully led the replication of HCCS, receiving approval from the New York State Board of Regents to open the second HCCS campus on Staten Island.

Under Christina?s leadership, HCCS Park Slope was designated a National Blue Ribbon School by the U.S. Department of Education and recognized by the New York State Education Department as a High-Performing, Recognition, Reward School.

Christina is especially proud of the innovative and enriching programs developed under her leadership, including comprehensive instruction in all four disciplines of the arts, coding, STEM education, theatre productions, and international travel opportunities that allow students to conduct research abroad, among many other initiatives that expand learning beyond the classroom.

Christina is a long-standing member of the Cahn Fellows Program for Distinguished New York City Principals at Teachers College, Columbia University, where she has been a fellow since 2007 and currently serves as an advisor for many years. She is also a Trustee of the Brooklyn Public Library, serving on its Library Operations Committee.

Earlier in her career, Christina served as Principal of P.S. 170 with the New York City Department of Education and as Director of the Drug and Alcohol Abuse Prevention Program for Community School District 20. She began her professional journey as a public-school teacher at P.S. 186 and P.S. 105 in Brooklyn, with her first teaching position at Holy Cross Parochial School.

She holds a Master?s Degree in Elementary Education with a concentration in Reading Instruction, a Sixth-Year Certificate in Administration and Supervision, and School District Administrator Certification.

Born and raised in Brooklyn, Christina continues to serve the city where she also raised her family. At the heart of Christina?s work is a lifelong love for children and the joy of teaching.

She also cultivated strong partnerships with the Greek government. With more than 20 years of leadership at Hellenic Classical Charter Schools, Joy currently manages over $20 million in annual budgets, has overseen multi million dollar capital expansions, and has secured over $1 million in grant funding.
