From what I have heard, Instituto Iberia is a good school for Spanish speaking children.
Holy trinity seems to be a school for New York bred Dominicans and other foreigners that can't afford Santiago Christian School. My sources say it is not so hot.
Iberia enjoys a long time fame for discipline and solid teaching (at least it did when it was on Calle del Sol). And my grandson goes there and his mom is the head of the Psych Dept at PUCMM so she must know something.
