Los Medanos College (LMC) is a two-year community college located in Pittsburg in Contra Costa County, California. LMC has an extension in Brentwood. The name, meaning "the dunes" in Spanish, refers to the sand dunes that characterize its location in eastern Contra Costa County. The college, opened in 1974, is one of three publicly supported two-year community colleges in the Contra Costa Community College District (along with Contra Costa College and Diablo Valley College). Current enrollment is 14,000 students. LMC currently offers 33 different associate degrees and 24 certificates of achievement. Many students complete their first two years of college here and transfer on to 4-year colleges and universities all over the country. Others move right into a specialized career or enhance their skills. The college's facilities were expanded significantly with the completion of a new library and math building in the summer of 2007, and a new science building in the spring of 2008. This expansion increased the available instructional space by approximately 50%.
