A Message from Principal

Emilia Herrera, Ph.D.

Welcome to A.O. Marshall Elementary School - Home of the Mustangs!


A.O. Marshall Elementary is a nurturing environment for our bilingual, general education and special needs students in grades K-5.  We pride ourselves on our ability to connect with our students and their families.


We are an early start school and encourage students to arrive as early as 7:45 a.m. for breakfast.  Classes begin at 8:00 a.m., so please make sure that your child is in the building by that time.  Our administrative team is hands-on and most mornings you will see us welcoming our students. Ms. Darlin is typically in the car rider lot conducting student drop off and I can usually be found near the main entrance, ensuring our students are following our safety protocols.


Join us online for our various virtual family engagement events and follow us on twitter.  We are hoping to return to in-person family engagement events once it is safe to do so.


Join us in our quest for excellence at Marshall, where college begins today!
