Excellent school in every way. Both daughters (one already graduated) have loved their experience here. Great friends, great teachers, great counselors, academics, sports, etc. An All-American school, and by far the best in the County. They don't even consider inter-district transfers due to it's so may people outside the boundaries trying to get in, so if you attend here, consider yourself very fortunate.

The counselor has been very helpful in choosing classes my child is interested in. The technology program is current, with all new computers and software. The principal really administrates this school effectively. It is safe and there are zero "gangs" which can be find in other neighboring areas.

We took a tour of the school and love the people and the location here in Rancho Cucamonga. We just moved to this area and are looking forward to great things for our children.

Los Osos is an amazing school! I wasn't as motivated freshman year to do so good, But my teachers did everything they could to help me. They are very flexible and are willing to do whatever it takes to make sure you pass. Also the best High School in San Bernadino County!

Los Osos High School. Let me just say first off, it is the best high school in Southern California. Everything, and i mean everything is perfect about LOHS. It surpasses Rancho Cucamonga High School as well as the rest! With the outstanding principle, Mrs. Petrocheli , This is still the top school.Also WE ARE NOW A CALIFORNIA DISTINGUISHED SCHOOL! We made it to the top 10! Our API is through the roof and all we can do, is till go further up! Go LOHS Grizzles!

Great ACADEMIC program and reputation. Teachers I have interacted with show genuine concern for the success of all students through professionalism and upright character. Lots of school spirit and the office staff has always been friendly and helpful.
