School Reviews
5 11/7/2022
Don Bosco Technical Institutes are known throughout the world for their STEM programs. We are fortunate to have one here, especially in Southern California. I am glad that my son (Class of 2022) attended this high school and is doing well in his pre-computer Science prerequisites such as Calculus and Physics. My son will be the third Bosco Tech graduate in our family, two of which are graduates of Don Bosco Technical Institutes in the Philippines (Makati and Mandaluyong).
