Slides of Diamond Bar High School's construction in 1981 were recently discovered while cleaning out files in the school's administration office. When our school opened its doors to students for the first time 35 years ago, it was made up of five buildings, including the gym and locker room. Today, the school has ten buildings, including an aquatic center, and is in the planning stages for a new instrumental music building. We hope you enjoy this look back as we begin our 2017-18 school year.
