Open Quote Our daughter was redistricted to Sun Valley this school year. Initially, we were reluctant as we were happy with the school she had been attending. Much to our surprise, the transition was not only smooth, it has been very positive. Our daughter is thriving both academically and socially. From administration to teachers, she has been welcomed. Her classes have been challenging and she has thrived. We could not be more thrilled. I encourage all prospective students / parents to talk with current students / parents. You will be astonished at the overwhelming sense of community and pride - which is just a bonus on top of the quality education in your child's future at Sun Valley. Welcome to Sun Valley Spartans!!
