There is nothing to pick from. Sorry, I could've helped!
No improvement to this sentence is necessary. It makes perfect sense on its own and sounds right. "Either" always takes an "or" else the word wouldn't make sense, as it's meant to contrast binary options.
eg.
I'm either going to eat food or drink water.
Dear Yale,
Can you please give me a tour of the school. Can you tell me the classes, you are teaching.
