Hear from Our OCASA Families

Our family has been part of OCASA since my son started Kindergarten, and now, as he prepares to move on from 5th grade, I can confidently say this school has been an incredible place for him to grow. Academically, he has thrived, but what truly sets OCASA apart is the well-rounded education it provides. With two teachers in every classroom, he gets more support and guidance than he would in a traditional public school. Beyond academics, I love that he has the opportunity to learn from multiple elective teachers, work on hands-on projects, go on multiple field trips a year, and collaborate with his peers in meaningful ways. As the PTA president, I’ve also witnessed the strength of our parent community—families, teachers, and staff all come together to create a nurturing environment where every child can succeed. The mission says we are a "joy-filled school and you can feel that in the classrooms and on campus every day.
