Welcome to Montessori School of Oceanside! We are a family owned and operated Montessori School. We offer individualized care to Infants, Toddlers, Pre-School and Elementary Students! We provide quality care in a nurturing environment for children ages 6 weeks to 6th Grade! Nestled on the border of Oceanside and Vista, our School provides exceptional education, daycare (as part of our before and after school program), and a variety of programs (including P.E., Music, and Spanish) to immerse your child in a world of learning! Welcome to MSO, where children learn, how to learn!
