Mrs. Tanikawa brings over two decades of experience in public education and has proudly served in the Tustin Unified School District for nearly half of her career. Before becoming principal at Hewes Middle School, she served as an assistant principal at both Beckman High School and Bolsa Grande High School, where she oversaw curriculum and instruction and led initiatives to support student achievement and staff collaboration.
Throughout her career in secondary education, Mrs. Tanikawa has helped establish a comprehensive school counseling program, expand Career Technical Education (CTE) pathways, and develop systems that support Dual Enrollment opportunities.

Mrs. Tanikawa believes great schools are built on strong partnerships among students, families, teachers, and staff. She is committed to ensuring the Hewes team has the tools, resources, and support needed to help all students thrive. Her leadership is grounded in collaboration, continuous improvement, and a deep understanding of the school community.
Outside of school, Mrs. Tanikawa enjoys spending time with her family. She is a proud mother of two sons and wife to a wonderfully supportive husband. Together, they value staying active, spending time outdoors, and enjoying shared experiences that keep them connected.
"It’s an honor to serve the Hewes community. I look forward to continuing the meaningful work happening here and building a bold future together with our students, staff, and families."
