I was so not impressed with her. I've been a cancer patient almost 9 years and regular oncologist moved on from Fox Valley he was an awesome oncologist. And I will not return to Dr. Gremminger I did not feel comfortable or cared or feel reassured in any way shape or form.

I had breast cancer in 2014 and received treatment between oct 2014 through March 2015, with follow up appointments after my chemotherapy. Karen was always very knowledgeable, very understanding and caring. I liked her not only as my Doctor but as a person. I highly recommend her to anyone who needs a good oncologist.
