Riverside Academy opened on September 18, 1970, serving grades 1–12, with Pre-K and Kindergarten added later. What began as a small campus built with parent volunteers has grown into a full academic and athletic facility. Mrs. Holly Haase is the current principal.

Over the years, Riverside added new elementary, middle, high school, Pre-K, cafeteria, gym, and athletic facilities, with major expansions in 1983, 1985, 1994, 2002, and 2009.

The Rebels joined the LHSAA in 1986 and have won state championships in baseball, basketball, softball, and track, while competing successfully in other sports. The Marching Pride of Riverside also performs at football games, competitions, and Mardi Gras parades.

Today, Riverside offers advanced and AP courses, modern technology and science labs, and has a strong record of academic achievements, scholarships, and community support.
