Spencerville Adventist Academy (SAA) was built on a foundation of love and sacrifice by parents desiring a Christian education for their children. In 1943, two years after the Spencerville Seventh-day Adventist Church was organized, a one-classroom school opened with seven students and one teacher, Miss Ruby Ingle. Every church member worked to get the classroom ready. In 1947, the church members saved money to build a new church. However, they soon realized how important the school was and voted instead to use that money for a two-room cinder block school. The church members built those classrooms through hours of labor—particularly Edward Reifsnynder.

By 1953, the enrollment had grown, and parents rallied together to add a third classroom and a third teacher. In 1956, the gymnasium was built and finally, in 1964 the three-story brick structure, housing the library, offices, and ten classrooms, was constructed. In the fall of 1997, the parsonage on the property was renovated, renamed Vandeman Hall, and became a part of the educational facility.

The church built a new state-of-the-art, green building in 2011, and the school was relocated to 2502 Spencerville Rd, Spencerville, MD 20868. Currently housing approximately 425 students in PreK to 12th grades with a faculty and staff of 50. The school is dedicated to offering a quality academic program that centers around developing a deeper relationship with Jesus. The constituency remains committed to supporting and partnering with the school to fulfill the mission.
