    About Us

    Los Altos High school opened its doors in 1958 and currently has 1702 students in grades 9-12.  We are located twenty-two miles east of Los Angeles, in the suburb of Hacienda Heights.  Our school motto is "Conquerors Think, Thinkers Conquer" which is a true representation of who we are and what we strive to be. 

    We have a long tradition of excellence in academics and extracurricular activities which has given us the reputation of being one of the best well-rounded educational schools in Southern California.  We have received numerous recognitions each year at Los Altos, some of which have included the California Business for Education Excellence Honor Roll, California Distinguished School, Best High Schools from U.S. News & World Report, and Newsweek's America's Best High Schools.
