"Dr. Greenberg has the best bedside manner that I’ve seen in many years and as a nurse, that says a lot. I took my dad to his appointment because he gets nervous at doctor visits and he made the entire appointment painless. He listened to my dad ramble for easily 30 minutes and listened to every word that came out of his mouth, even if it didn’t exactly correlate to what he was asking lol. He took his time explaining everything to us. Never once made it seem like he was busy with other things. He went above and beyond to make sure my father got his medications in a more affordable way since they can be so expensive at some pharmacies. 10/10 recommend. My mom will be going to him now too because my dad raves about him, and never once has he raved about any doctor"

"I went to the Illinois Gastrenterology for the first time to have my COLONOSCOPY. I have been seening Dr. Greenberg since probably the early 1990's. I have had him do my COLONOSCOPIES at St. ALLEXIUS hospital in Hoffman ESTATES since I live in Streamwood. This time his office suggested that I have my test done at their office in Arlington Heights. It truly was a pleasure doing my procedure at the Illinois Gastro office rather than the hospital. It was so much easier 1 to find a parking spot 2 the staff at Illinois Gastro is very kind and very hard working and they get you prepped really fast and the anesthesiologist is supper kind and she gave me just enough of the sleeping stuff that I woke up quicker and I never woke up during the procedure. Well, I can't say enough about Dr. GREENBERG because he is a very nice person and his bedside manners are fantastic. He explains everything before your procedure and after your procedure when he gives you your results. So like I said the Illinois Gastro CENTER is so much better and easier to go to and they work quicker and Dr. GREENBERG is awesome he has been my gastro doctor for way over 20 plus years. Along with every thing I have said about Illinois Gastro CENTER and Dr GREENBERG also he is my wifes Gastro Doctor as well. My wife explains Doctor GREENBERG as very gentle with his bedside manners as well as she will now get her procedure done at Illinois Gastro office also. The Center is so much better to go to than the hospital. Don't hesitate to try it you won't be disappointed at all. I give them 5 STARS. THANK YOU ALL FOR YOUR WONDERFUL SERVICE INCLUDING DR. GREENBERG. 👍"

"I've been going to Northwest Gastro for many years. I had seen one of Dr Greenberg's partners until he retired a couple of years ago. Since then, Dr Greenberg has been working with me. I'm very happy with his care. He is not just a "good doctor". He gets to know you and cares not only about your health but your well-being. I suppose this means he has a great bedside manner. I feel as if he truly cares and this is demonstrated by his interactions. I highly recommend Dr Bruce Greenberg for those needing a Gastroenterologist."

"The first time I came to this practice was about 15 years ago. When I recently looked at the names of the doctors in this practice via their website, I think many of them are now unfamiliar to me (newer and younger), but I was happy to see that Dr. Greenberg stayed on. He’s been my doctor from day 1 (2005) when I was first diagnosed with colon cancer. I find Dr. Greenberg to have good listening skills, a gentle, compassionate, and personable doctor.."

"I’ve known who Dr. Greenberg is for years, as he’s on staff at a hospital I once worked at. Then I came across him again when my spouse was almost killed by a surgeon who screwed up a simple gallbladder removal. I requested his group, he showed up and was super compassionate and made sure that my wife received the care she needed by the individuals who were best suited to help her even though it wasn’t him - it was one of his partners. He didn’t let ego get in the way. When it came time for me to see a Gastroenterologist, I did not hesitate to go to Illinois Gastroenterology Group. He took his time with me, was very thorough, asked how my wife is, and he made sure that my next procedure appointment worked with my work schedule as getting a day off is not always an easy task. He’s not just a good doctor, he’s a good man. I would definitely recommend Dr. Greenberg."

His nurse Donna has returned my calls within less than 24 hours. His staff on-site has answered all my questions. I am usually seen with 20 minutes. I am more than satisfied with Dr. Greenberg and his staff. I would definitely recommend him as a wonderful and caring physician."

"Dr. Greenberg and his staff were supportive and informative, making the entire experience stress free. Besides obviously being a highly regarded member of the medical profession, Dr. Greenberg actually puts patient medical needs ahead of all else. Thus, if a younger member of his group has more expertise in an area that would best benefit the patient, Dr. Greenberg encourages the patient to have his associate take the next step in treating the issue. I think Dr. Greenberg is the epitome of what all doctors should strive to be.... Thorough, informed, caring, willing to discuss all aspects of the situation. Dr.. Greenberg called me from his home one evening to discuss the pathology report and to assure me of the person he wanted me to see for resolving the issue without invasive surgery. He even suggested something to add to the 'prep' to make it more palatable. Highly recommended by me. I don't hand out rave reviews lightly."

Always remembers to reach out to me whenever blood work is due, very easy to talk to and to get a hold of when in need. 10 stars if it was an option!"

"I was a patient of Dr. Michael Cohen for 10 years and saddened when he moved back home to Florida. Before he left he called me in to see him because he wanted me to hear from him not the letter that would be sent out. He told me had had thought about who would be the best match in the practice for me and chose Dr Bruce Greenberg. That kind of over and above caring is greatly appreciated. His choice was right on the mark."
