ANDREW CHRISTENSEN MIDDLE SCHOOL

Christensen History

Andrew N. Christensen was a long time resident of the Livermore Valley and served on the Board of Trustees of the Green School District for 19 years and was a member of the Board of Trustees of the Livermore Joint Union High School District for 14 years. In addition to his community and civic participation, Mr. Christensen was also a cattle and horse rancher.

On June 29, 1966, the Board of Trustees of the Green Joint School District of Alameda and Contra Costa Counties passed a resolution to rename the Greenville-North Site #1 school site Andrew N. Christensen School.

Established in 1972, Andrew N. Christensen School was a grades 3-6 elementary school in 1972. In 1977 with the closure of Green School, Christensen became a K-6 school.  After a school board decision to move grade 6 to middle school, the District established Christensen as a K-5 school. Grade 6 was added back in 1990, grade 7 was added in 1991 and grade 8 was added in 1992. In 1991, the school site completed a remodeling process with the addition of new classrooms and administration building. 

With the opening of Leo Croce Elementary School in 1991, Christensen transitioned to a 4-8 school.  When Altamont Creek Elementary School opened in 2000, Christensen transitioned to its present configuration serving grades six through eight and became Andrew N. Christensen Middle School. We are able to accommodate more than 800 students, a capacity we have not reached. We are proud to have 36 spacious classrooms arranged in grade level or subject matter “clusters”. At the center of each cluster is a mini-courtyard, complete with benches and greenery, where students study, snack, and socialize when class is not in session. Our campus includes four science labs, two home economic teaching kitchens, a library, a gymnasium with locker rooms, two music rooms, a computer lab, a multipurpose room, a kitchen, an outdoor eating area and a courtyard and an administration office.
