    "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!"
