Please don’t be to alarmed by what you heard! While not ideal what happened, it could easily happen anywhere. Old building or new, sometimes things just happen (Think of all the flooding problems Elmhurst had.)
On another note, my DD left Elmhurst at end of YR 8 to attend YDA and absolutely loves it! YDA has a very high standard. No school ticks every box but I’m sure no student does either. It’s more about choosing the right fit at the right time and if you make a mistake it’s ok, just find the other options that fit. There are many routes to the final destination and plenty of detours along the way. Don’t let any one thing be the be all and end all. I’m sorry YDA turned out not to be an option for your dd, I personally highly recommend it. It’s not for everyone though and I’m sure the girls that left YDA to attend Elmhurst are just as happy with their decision and I wish them well.
