My mother attended in the early 60's. She said it was the best thing that could have happened for her. She kept up a correspondence with one of the nuns many years after she had left. She said the school was for trouble makers as well as girls who were "in trouble" as it was worded back in the day.
I went by there just this past weekend and found the original building had been turned into a strip mall of sorts, which I found to be kind of sad to see but still a beautiful building.
