TREE Academy has been incredible for my child. From our first tour, we could tell that TREE offers something very different. The staff takes time to understand each student, and the environment feels friendly, respectful, and supportive.Since enrolling, she looks forward to school each day. She is making real friends, discovering new interests, and re-engaging with her classes. The small class sizes and caring teachers help her feel seen, and the personalized approach has helped her catch up in subjects she once avoided.What stands out most is the sense of belonging. TREE creates a space where students can learn without fear, explore who they are, and regain confidence. It has truly changed our child's relationship with school, and we are very grateful for the joy it has brought to our family.

Hi,We are looking for a nice, friendly school, with up to 18 students in a class. Boys and girls. Preferably international diverse students, where a foreigner does not feel like a stranger and where you can make friends. We used to live in Manhattan for 5 years and just last year we moved to California. Our school was not a good fit for our daughter.
