I had difficulty getting a recent appointment when I called so I went in early next morning and managed to get an appointment with another doctor for that afternoon. My family practitioner also called back with an appointment time. I saw the other doctor and was satisfied with his service.

Dr. Hecker is a very bright physician. I am confident in his diagnosis and care plan. He tends to try and speed up the appointment by filling in words while I am taking. I suspect he does this doc to the way his brain is wired. I don't believe this is fixable but that is OK. His positives outweigh the negatives. No one is perfect.

Dr. Hecker should not be in patient care. I have never been treated with such disrespect because the staff double booked him, like it was my fault.He was mad because he stated they don't think I need to eat. Then he stated don't come see me if you see another dr. I have heard how horrible of a person he is and was reluctant in seeing him, but I needed a physical for school and he was the only one available. He is rude and talks to patients as if they are idiots, along with his staff. I will never see him again if my primary is unavailable I will wait for her.

Reviewed on March 11, 2019 7:00 PM

was dismissive when I told him what was going on. He said I was diagnosing myself. yet in the end, that was exactly my diagnosis. it wasn't too difficult to diagnose, I needed to know how to fix the issue. He chastised me for not making a long enough appt. I called and told the desk what I needed the appt to cover. it is not my job to determine appt length. in the end, the doctor told me I would receive a larger bill because I had more than one issue to discuss. it is inappropriate to discuss billing with patients.

Not happy that he didn't fill out the Medicare form and fax it to Walgreens in Fox Lake. I have been waiting for my test strips but can't get them because of this form. I may be looking for a new doctor because this is unacceptable.

I like my Dr. but was discouraged that during the physical he never asked if I had any health concerns. When I tried to bring them up he over talked me and would not listen. Like he had the answer before I even asked it. Seems to dismiss me. He spent half the time inputting information in the computer that was lost with the aurora conversion. Asking me questions my medical records should have shown.

Reviewed on February 17, 2019 6:00 PM

The doctor was knowledgeable and I appreciated the extra time he spent since this was my first time seeing him, however, he lacks bedside manner. He interrupts and assumes he knows what your going to say. He is not a good listener and seems dismissive. I thought I was there to discuss my overall health and any concerns I have but he kept saying that discussion was for another time. I don't have the time to go to see the doctor multiple times to ask simple questions. I would think he would understand this as it seemed he didn't want to waste his time either. Maybe more time should be scheduled for first visits so that the doctor does not make the patient feel rushed to get through all the medical history as well as current concerns. Not an overall good feeling after I left.

the most annoying and perhaps dangerous situation is the fact that the electronic medical records from the Advocate Medical group are not accessible by providersin the hospital group. Really providers at the advocate hospital who get a referral from Advocate Medical group have no electronic access to the patients medical records.This needs to be corrected.. if not I will consider going to a provider group were the hospital and medical groups share the electronic records of the patient.

My last visit with Dr Hecker was for a EKG check up for Cataract Surgery. So it was mainly to make sure my heart was stable. He was concerned when listening to my heart beat, but then the test came thru as fine, and he came back to tell me why my heart beat most likely sounded irregular and recommended I ease up on my caffeine. He said the test was a good way to make sure all was fine. He has always been very thorough and makes you feel that you are a special patient. If he has any doubt on a test, he has me return to redo and make sure all is good. If I forget something or question something about an appointment or a medication I can send him a medical question on the my health portal and he either answers my question by calling me personally, or have his nurse call me, and usually sends me a return message also. I have recommended him many times to people who are looking for a provider.

Reviewed on October 16, 2018 7:00 PM

Overall I trust Dr Hecker and his opinion and treatment plans. My overall frustration has been every time I have seen him he has been abrasive, curt, and lacks empathy. His social skills are terrible and seem so rehearsed and insincere. Once I show frustration he inserts some bad joke or awkwardly long touch to my shoulder which shows he knows its an issue and is trying but he needs help. I believe he is a good doctor and I have no plans to see someone else. He just needs some coaching on how to interact with patients.
