Holy Angels School, Mathari, was established in 2003 under the guidance of the Sisters of the Holy Angels. The school began with a simple yet powerful vision — to shape minds and nurture faith through quality, value-based education with its motto as Integrate in Simplicity. It started as a Pre-School with only a few learners, a handful of teachers, and a deep commitment to providing a loving, disciplined, and faith-filled learning environment. Classes were held within the holy Angels Sisters compound, where teachers focused on holistic child development — spiritually, academically, and socially.
