All school campuses in the Walnut Valley Unified School District, including DBHS, will be closed through the remainder of the 2019-20 school year because of the COVID-19 pandemic. We are transitioning to online instruction.

Nicole Cabase Named New Instructional Dean


Wednesday, June 21, 2017, our Board of Trustees officially approved biology teacher Nicole Cabase as our newest Instructional Dean!

We are very fortunate to have Mrs. Cabase join our administrative team and help lead our school. She will be an addition to the three instructional deans who are currently part of our leadership team, Gabriel Aguilar, Matt Brummett and Whitney Prenger.

Nicole came to Diamond Bar in 2007 and has taught Advanced Placement Biology, Biology Honors, Biology, SDAIE Biology, and Integrated Science.

She filled the rolls of Department Chair of Science a year ago and Interim Grade Level Coordinator this past year.

In all of these positions, Mrs. Cabase has done an outstanding job. We are so excited to welcome her to this new leadership role!
