My son is a new student at KJMS this year and it has been such a great experience for him and our family. His grades are higher than ever (he is in 7th grade)! He loves his classes, teachers, and peers. He has joined some interesting programs and especially enjoys having an art class as part of his curriculum. I am so proud as a parent to be a part of the KJMS family.
