It’s an interesting selection. From people I know, I have heard nothing but great things about Mr. Hirschfeld and their interactions/experiences with him.
However, at the same time, my understanding is that he served as Rector at St Paul’s during a period that had a lot of turmoil for the school and questions about how the school leadership (board and administration) handled it, ultimately resulting in the school having to accept a NH state overseer that doesn’t report to the school.
So seems like a bold, independent, and a bit surprising selection. Might be great, I don’t have a view and don’t have the necessary insight for a view. However I’m generally a fan of going against the grain and making controversial decisions if you think they’re right.
