Saints Constantine and Helen Cathedral
Founded in 1913, St. Constantine Church was the first Greek Orthodox Church on Long Island before becoming Brooklyn’s Cathedral in 1966.

At a Glance
The Cathedral is a center of the Greek Orthodox Faith and Hellenism in Brooklyn, and is visited by many dignitaries from Greece, Cyprus and the United States.
Christians of the Eastern Churches call themselves Orthodox. This fifth century description means “true praise.” In other words, to bless, praise, and glorify God the Father, Son, and Holy Spirit is the fundamental purpose of the Orthodox Church.
While the Orthodox Church contains individuals from numerous ethnic and cultural backgrounds, a large percentage of her membership is composed of persons who were born in America. In recognition of this, Orthodoxy has been formally acknowledged as one of the Four Major Faiths in the United States.
Following the practice of the Early Church, Orthodoxy treasures the various cultures of its people, but it is not bound to any particular culture or people. The Orthodox Church welcomes all.
There are about five million Orthodox Christians in the United States. The largest Orthodox Christian community is the Greek Orthodox Archdiocese of America, which has about 500 parishes throughout the United States.

Meet the Dean:
Father Evagoras Constantinides
“Our A. Fantis School is much more than just a school. It becomes a home to the people who make up our family, and we work hard to cultivate that warm and accepting environment. We are unique in who we are, yet we are proud of who we are. We are a Greek Orthodox School, and we strive to make understanding of both Hellenic culture and our Orthodox Faith a reality of each and every day”.
- Fr. Evagoras

Frequently Asked Questions
Yes! Fantis is a welcoming community, and we have families of many different Christian denominations and cultural backgrounds. A baptismal certificate is required for K-8 students. We are happy to assist with this process if needed. Please contact us with any questions.
Faith and love of God are foundational components of our A. Fantis education. K-8 students begin each morning in the cafeteria with a prayer. Religion class is held weekly and teaches the basics of Christianity before the deeper study of iconography, service-learning and comparative religion analysis in middle school. Monthly liturgy is held in the Cathedral adjacent to the school, to celebrate holy days and help students practice their faith. Rooted in the Greek Orthodox tradition, the majority of the religion curriculum and liturgy overlap the core tenets of Christianity. Please note there is no religion or religious instruction in UPK4 classrooms.
Daily PK-8 instruction builds bilingual fluency, cultural literacy, and cognitive benefits. Music is part of this, with students learning Greek poetry, Orthodox liturgy, and works of Greek composers. The school choir expands this connection through contemporary pieces, language learning via song, and a long-term goal of three-part liturgical music in the middle school choir.
