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.

Mock Trial Team Among Top 24 In County


Our team is in the Top 24 of the 100 teams participating in the 40th Annual LA County Mock Trial Competition. The second week of September, our DBHS team began practicing and creating its argument for this year's case. After two months of daily practice, hard work and strong team spirit, they continue this season undefeated and will compete in the first elimination round Monday, November 13, at the LA County Courthouse. If the DBHS team wins, the next round will be the top 12 on Thursday, Nov 16, with subsequent rounds being held after Thanksgiving break.
