Dr. Greg J Jun, MD

On a good day Dr. Jun was impatient and rude. Normally he would scold me, laugh at my description of symptoms and be dismissive. On my very first encounter he was mad that I checked in at the front desk 3 minutes past my appointment time. In my last appointment when I mentioned that I had more issues to talk about, he stopped me and said he didn't have time for more than one or two issues per appointment. Well what if they were interrelated? My 19 year old son went once to see him for severe hip pain. He came home and said he was never going back to him again. He said it was the worst experience with a doctor ever. It was just announced that he left Fox Valley Internal Medicine after just a few years. Take a look at all the health systems he's worked at. Why does he bounce around so much? Is he chasing the money or are patients chasing him out?

Dr. Jun told me there was a limit on my medical concerns per visit. Dismissive, condescending attitude. I had to beg for a referral for an ENT. He said large painful bumps on my throat and tongue were normal and laughed in my face when I asked if someone can swab or culture the bacteria. He said there’s nothing to swab. I will never recvommend this lazy jerk to anyone.

Non accommodating!!!!

Great doctor. I just wish I can find out where he is practicing now.

He has been my doctor for 8 years. He is a great doctor. He keeps up new treatments and whether new medicines would improve treatment.

Dr. Jun is a true partner in our healthcare. He listens well, is current on the latest research, and genuinely cares. In the time my husband and I have been seeing him, we have each had some serious health issues crop up. Dr. Jun has taken appropriate action in every case, earning high praise from the specialists to whom we were referred.

Dr. Jun is a fantastic doctor. He truly cares about his patients. My daughter was having emotional problems, depression...and Dr. Jun gave her his number and told her to call him anytime. I've been going to him for about 7 years now, and I just love him!!!

I had this doctor but then he joined Aurora Health Care. I didn't know where he went but then I finally found him. He is young but experienced. He actually sits down and listens to me.
