In the fall of 2010 I went to Dr Sloneck with rib pain. After several tests including blood and X-ray Dr. Sloneck called me late in the evening and suggested that I may have something more serious. He suggested a cat scan and directed me to an oncoligstist The diagnosis turned out to be multiple myeloma, a blood cancer. After treatment I am in complete remission. I am still on maintenance - and still going strong due to Dr Slonecks great medical incite. Thank you Dr Sloneck who kept After me and calling me when I did not respond at first. Dr Sloneck is truly a dedicated Doctor. I am grateful!

I've been seeing Dr. Slonek for quite a few years and have never had a bad experience. My wait time is usually minimal but has been 45 minutes twice. I love being able to review my visits and test results on line, it's very helpful. I can't say enough good things about this doctor and DMG in general.

Dr. Slonek quickly diagnosed a rather serious form of cancer, notified me and gave me direction to my next step for treatment. Because of his diligent follow up, I have been in remission for more than 4 years and continue maintenance therapy.

Excellent and caring doctor. I have recommended him and will continue to do so. He has been an immense help when other doctors didn't seem to want to be 'bothered'. I can't say enough good things about him.

Made an appointment a month in advance based on the good reviews since choosing a new doctor. Waited in the examination room for over an hour. I had to leave but at the front desk, I had to wait for 10 more minutes to get the copay back, i asked if he is done and the massage from the doctor was that since I told them I was leaving, I have to wait for another hour to see him. Total disregard of my time. And, no one bothered to even apologize. Our whole family will be pulling out of Dupage group.
