Walnut High School Reviews
I am completely amazed at the level of education Walnut High School provides. Teachers, including the staff are very helpful and I’m impressed with the overall character of the students. I’m confident we made the right choice placing our child as a district of choice transfer. Best of all, our child loves it here!
