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.

Ryan Seacrest Coming To Celebrate Band Director's Award

Dear DBHS Students and Parents,


It is my pleasure to invite the entire Diamond Bar High School Community to join American Idol’s Ryan Seacrest, The Grammy Foundation, KIIS FM, and the Ford Motor Company to celebrate Steve Acciani being named a national semifinalist for the Grammy Music Educator Award on Tuesday, November 11th at our campus!


Please feel free to come and help us support the Diamond Bar High School Music Program! We will be participating in the Ford Motor Company’s Drive 4 UR School national test drive program to help raise money for our outstanding music program.


GRAMMY Foundation Honorary Chair Ryan Seacrest will be on hand to join members of the Diamond Bar community who participate and support DBHS by test-driving a new Ford vehicle. For every person over 18 who test-drives at this one-day event, Ford Motor Company and Fairway Ford will donate $20, up to $6,000, to Diamond Bar’s music education program. 


The event will also feature all 700 of our instrumental music students performing, and be hosted by KIIS FM. The event will take place on Tuesday, November 11, from 11:00am until 5:00pm, with Ryan Seacrest expected to be here from 1pm until 3pm. Food trucks will be on hand, so come spend some time enjoying an afternoon out with the community.


We’d love to see you there!



Principal Catherine Real
