[General] There are many....

[Silverobama]

I wrote the following sentence:

There are many excellent and outstanding people here whose English are impeccable and from whom I can learn.

I said the above to a woman in an online chat group, wanting to tell her that the group we're in is a great one and I can learn from people there.

Is the italic sentence natural?

The second "are" needs to be "is": [Their] English is impeccable, not [strike][Their] English are impeccable[/strike].
