I feel the same way. Our entire program is successful largely because of the efforts of my assistant. She solves many problems before I even bring them up. She is a big reason why I love my job, and if she left I think I'd have a tough time replacing her.
I just wanted to brag on my young assistant director who has done an incredible job. Way above and beyond expectations.
As said by a colleague last week, “Many directors would love to trade their assistants.” If he sticks with it, he will be a legendary teacher one day.
