Mrs. Plony- Bais Rochel officially isn’t considered chasidish, they call themselves heimish. yet the teachers all teach in Yiddish, they daven sfard, and most of the girls come from chasidish or tuna beigel families..
And btw I think now BYR is more yeshivish than BYM- they are more close minded, and are not as willing to accept girls from less yehivish backgrounds, thus resulting in generally 1 type of girls.
