Our Mission & Philosophy
“To awaken a love for God, a desire for learning and service to others.”
Three Sisters Adventist Christian School is owned and operated by the Seventh-day Adventist Church.
It is our purpose to provide a Christ-centered academic environment where students are nourished spiritually, intellectually, socially, physically and emotionally.
We believe that while knowledge of facts and the ability to think are necessary for a person to succeed in life, they are not all-inclusive.
True success includes a positive outlook on life, which comes from a complete and active faith in God and acceptance of His love.
We believe that serving God gives us purpose, inspires a sense of identity, and motivates us to serve our community.

Student Life Photo Gallery
We pride ourselves in the fun we have while learning! Play is the number one way for children to learn – it helps them retain what they are being taught, and it also helps develop a love for school and education. Here are some photos from over the years of our many field trips, extra-curricular activities, and special events.
