There is a tumor attending at Cook County as far as I know. His name is Walter Virkus--he is a tumor and trauma guy. He is on staff at Rush, and is actually Dr. Gitelis' partner. But he does see patients at County, and takes care of public aid patients, so he does work with those without insurance. I'm not sure if he operates out of County, he might only operate at Rush. I've heard good things about him, and Gitelis and he operate a lot together on the more difficult cases. Hope this helps.
