School Notes

  • Annunciation Orthodox School, having grown from a ministry of the Annunciation Greek Orthodox Cathedral, celebrates the diverse and individual qualities of all children and their families. AOS provides a superior education in a secure and stimulating Christian environment which encourages the individual child to achieve academic, spiritual, emotional, social and physical excellence, and to become a responsible member of our society.
  • The learning environment at AOS encourages students to try something challenging, take academic risks, and abandon the fear of failure. Public speaking is a hallmark of the school, and AOS educators are committed to providing students with an engaging curriculum in a nurturing environment. They instill excitement for the discovery of knowledge while motivating students to reach individual goals and explore their unique strengths and talents. With its close proximity to the museum and performing arts districts, medical center, major universities, libraries, downtown, and zoo, the acquisition of knowledge occurs both inside and outside the classroom.

AOS is a wonderful school. My son is in Pre-K and he loves going to school every day. The school is a nurturing environment that also provides a diverse and challenging curriculum. In addition to academics, the school also focuses on developing the students moral character and sense of community. It is a school that places community service as one of its priorities. AOS is a great community with extensive parent involvement. The new addition to the building is beautiful. The space is open and full of light. You really see all the hard work and dedication that was put in not just by the school, but also by the parents in order to make it all possible. We have just started our AOS journey and we are looking forward to the many years ahead that we have to be a part of this community.

AOS is an amazing place! Warm teachers, administrators, and parent community. Challenging academics and faculty that are interested in capturing the hearts of young children to create a love of learning from early childhood. My young children (age 3.5 and 5) are exposed to a variety of Fine Arts, Athletics, Language, and other enrichment activities and we could not be more excited to see them grow into the mature, intelligent, and kind middle school children they have as role models at AOS!

AOS is the most well-rounded school. As a parent of middle and lower school students, I am impressed with the genuine culture of love and powerhouse academics. I wish every school could achieve what this school does, which is to help raise kind, intelligent and compassionate people.
