Diamond Ranch High School, high school in Pomona, Los Angeles County, California

Diamond Ranch High School is a public school in Diamond Bar that opened in 1997 and serves students from the surrounding areas. The campus spreads across a large hillside site and features modern, distinctive architecture designed by the firm Morphosis under Thom Mayne's leadership.

In 1991, local voters approved funding for new school facilities, with about 10 million dollars set aside for this project. The school opened in September 1997, initially housing students in temporary portable classrooms until they moved into permanent buildings in 2000.

The school takes its name from its location near the borders of Diamond Bar and Phillips Ranch, connecting it to the local communities it serves. This geographic reference shows how the school is woven into the fabric of the area where families live.

The school sits on a hillside in Diamond Bar and is easily accessible from nearby communities. The campus is large and well-organized, so it helps to familiarize yourself with the layout before visiting.

The building has appeared in films like The Cell and Orange County due to its striking appearance and has also been featured in television commercials. This recognition shows how distinctive the architecture is and why visitors are often surprised to encounter such a recognizable school building.
