This is 4 years late, but I just came across this site. I'm actually wondering where he is too and looking for anyone who may know him. I am an old friend. Kostia was a great dancer with a ton of stage presence. Really passionate about his dance (he put up with a lot of pain and ice to get through performances) and I was always amazed at his historical knowledge. He loved to listen to the music and imagine the movement. Yes, he made Principal at Pacific Northwest Ballet, but then left to teach. Which ballet studio were you at? I'd love to know how he is doing... Thanks,
