Mt. Diablo High School

2243 Mt Diablo St

Mount Diablo High School opened in 1905 on three and a half acres donated by AW Maltby. Many of the students came to school from surrounding towns. The original two story building was named for Bertha Roman who served as a teacher and principal for over thirty years. It was demolished in the 1960’s. The original gymnasium was replaced in the 1940’s. Still standing however, is an extensive array of buildings constructed in the 1920’s. Since the late 1930’s, population growth has lead to the construction of 15 public and private high schools in the area.
