Mimosa Elementary School was built in 1967 on the site of a horse pasture across the street from the Smith barn and house. The school was named for Mimosa Boulevard in Roswell. At the time it was built, Mimosa was surrounded by a large cornfield and housed 325 students in grades 1-7. The original buiding had 12 classroms and 12 teachers. The area has changed dramatically over the years from a small town setting to a densely populated city. In keeping pace with the growth of the area, an extensive renovation was completed in 1990 doubling the size of the school. In 2010 another addition added to the size of the school which grew to over 1200 students. Mimosa has had three mascots over its history - the mustang, bear and manatee. The manatee remains the mascot today and is featured in a hand painted mural spanning the entire wall of the cafeteria.
There have been eight principals at Mimosa Elementary since its opening in 1968.
