Rebecca Burton
Deputy Superintendent - Student Services & Special Education
Confidential Administrative Secretary II | Priscila Leyva
 
Mrs. Rebecca Burton has worked as a district special education leader for 7 years, and her favorite part of this work is collaborating and working with all team members to achieve wonderful things for our students and families, especially our most vulnerable students. Her work in education started as a teacher at a small special education school in Baja, California in 2006, where she also was a house parent for students with special needs. This really incredible time gave her the spark and passion for learning how to support all learners, all people, from any background; so she eventually went back to LA to earn a Master's in Special Education and Education Specialist credential. From there, she spent most of her years teaching middle school and high school, both as a General Education teacher and Special Education teacher, doing anything from mod-sev programs to co-teaching in high school ELA. She transitioned into district leadership in 2014, because she saw an opportunity to be an advocate for school educators of all roles, so that together, they could build work spaces that work better for all students. She really looks forward to getting to know our team, students and families here in Lemon Grove! In her spare time, you will find her reading like a maniac, going to parks with her husband Joe, daughter Sadie, and their dogs, and on a special occasion getting out for some horseback riding.
