Meet Our Principal

Ms. Theresa Johnson

Ms. Theresa Johnson

Born and raised in California, Ms. Johnson relocated to the San Joaquin Valley shortly after her high school graduation in 1986, attending Modesto Junior College and serving in the AmeriCorps Early Childhood Literacy Program for two years where she graduated with honors, earning an Associate Degree in Child Development. She became the Coordinator of the AmeriCorps Foster Youth Mentoring Program and received her Bachelor of Science Degree in Applied Studies, graduating with honors from California State University in 2002. She continued her education at CSU Stanislaus by obtaining her Multiple Subject Teaching Credential, Master of Arts Degree in Educational Administration, and her Administrative Credential.

Prior to joining Manteca Unified, Ms. Johnson served as a classroom teacher, vice principal, principal, instructional coach, and Director of Educational Programs. She has served in both traditional and charter school settings, and strongly believes in building a strong Multi-Tiered System of Supports that includes Academics, Behavior and Social Emotional components.

I am honored to serve the Great Valley community. I am committed to creating an inclusive, equity-based learning environment that values teaching and learning. Teachers will be empowered to be creative and master their craft of effective instruction that meets the needs of ALL learners, students will be empowered to achieve their fullest potential, and parents will be empowered to be involved in their child's education.
