How can find a person in Chicago?

I have  finished a English lesson online. And I really want to find the teacher. I have never seen him before, and only know his name is Robert Yore, a native in Chicago. He was an English teacher before, but now he came back to the collegue. To earn money, he teach Chinese student English in Hujiang(a website).

In this case, any possible to find him?
