I would not change a thing. The faculty and staff are amazing! My academic experience has been the best. I have also enjoyed the team sport experience with water polo, swimming, and volleyball.
I liked Los Osos high school and most of my teachers. My favorite teachers included Mrs. Diver, Mr Hartz, Mrs. Mcbride, Mrs.Elliot, Wrs. Grennan. I also liked the classes that they offered, especially Water Technology and Robotics.Water technology was my most influential class by far over my four years in the district because it showed me about the water industry and the water politics in California. This class made me want to be apart of the water district. Robotics was also very influential to me because this is the day and are that we are living in right now. If I were to change one thing about the school it would be the library. It contains our computer lab and it is not always open.
