"My entire family have patients of Dr. Lee and Dr. Janda for many years. Dr. Lee makes it a point of explaining everything in detail, which I definitely appreciate. I have also recommended Dr. Lee to many of my colleagues at the college, as well as close friends. We are fortunate to have both Dr. Lee and Dr. Janda. I also appreciate the staff, who are exceptional as well."
"Best GI Doctor! He takes his time to talk to you and answer all your questions. Really good bedside manners. Highly recommended by doctors and nurses who work at the hospitals he go to. Who else would know his work but those that work closely with him, right?"
"Dr. Victor is one of the best doctors I know. I was going through so much problems and pain for months with a different doctor. As soon as I got Dr. victor’s information I started to see him in a week he got me under control. No more and no more problems. He saved me. Thanks Dr Victor Thanks, Robert"
"I was s little hesitant about being put to sleep but everyone there put my mind at ease. Before I knew it it was over. I read reviews about people saying it seemed like it was over before it started. I would 100% agree. True professionals and very nice. The whole process didn't hurt either."

Obviously I knew something was going on cuz of blood , I found dr Astice and he did colonscopy a month later and found one of the biggest hemroids (internal) he ever seen! Dumb dr in Indiana should be fired!"
"Dr Lee is very friendly, nice, & patient besides the fact that he's very knowledgeable & professional. He asked about & listened patiently to my problem, explained what he suspected of my problem, & gave me suggestions on what I could try. He also had me set up appointments for the needed tests in the future. I'm so glad to have found such a wonderful GI doctord. I'd highly recommend him!"

"Staff is always kind and helpful. Doctor Lee has a phenomenal bedside manner. He is kind and caring, explains everything in detail. I trust him wholeheartedly with my health and well-being. He takes the time to help me understand my diagnosis and my bloodwork and other testing."
"Dr. Lee is the best! He is extremely knowledgeable & very determined to get to the root of your problems. He also has a great bedside manner. He is extremely kind, he listens & makes you feel comfortable. I have had a few procedures done with him, and he & his staff are wonderful. From the nurses, to the anesthesiologist & everyone involved, they all explained every step of the way & what to expect. I was extremely impressed with his anesthesiologist Barb, who broke down every little thing regarding my sedation. I have had many anesthesiologists & none have ever been as informative as she was. I highly recommend Dr. Lee!"
"Dr. Lee’s bedside manner is top notch and his team is impeccable! From prep to procedure, everything is explained throughly. Each team member has their part and nothing is missed. I’ve had about 4 colonoscopies and I only choose Dr. Lee because he makes this procedure so stress free! Thank you!"
"Dr. Robert Clark and his entire staff at Digestive Disease Consultants are exceptional medical professionals. I was referred to him by another doctor and I now know why. His demeanor is patient, knowledgeable, and attentive. When I arrive at his office I can be confident that he has reviewed my files and is well prepared to discuss my medical issues. He is easy to talk to and ensures I understand his responses. I highly recommend Dr. Clark."
"Dr Robert Janda has saved my life many times . This man is truly the extension of the healing hands of The Lord Jesus Christ. I was bleeding from the rectum due to side effects of chemotherapy, surgery, internal radiation and external radiation. Some Dr could not help me; but God used Dr Janda to heal me. The devil tried to kill me with hepatitis due to blood transfusion that I received years ago. But Dr Janda and Jesus Christ said “ no” to Satan. And I was healed without any injury to my liver. He has been my Dr for 12 years. His compassion for sick people drove him to Africa to do medical mission and many lives were saved. The Holy Spirit and I strongly recommend this Angel to you. He is a humble child of The Most God."
"Dr Bernsen is a fine physician. He literally saved my life during a gut bleed out of which the attending staff later said, “You don’t know how lucky you are. None of us had ever seen so much blood.” In addition to his competence he is personable, human, available and interested in me and all my life circumstances."
"I recently had a colonoscopy. The prep was the hardest part. Once arriving for my appt. the staff was most pleasant and set me at ease. Dr Robert Lee visited before and after the procedure. He was relaxed, took time to answer my questions and was very informative. I would highly recommend him."
"Nurse went over my medical details thoroughly before the procedure to make sure everything was correct. I especially was thankful they let me relax before procedure because my pressure was high. I was nervous. Thumbs up for that! Doctor was cute an funny,but very caring. The anesthesiologist came to talk to me before she put me to sleep. So did the doctor, that's team work. Would I recommend, yes, but don't steal my Doctor.Lol"
"On the day of my appointment with Dr. Robert C. Kaiser I was registered quickly by the nurse. I didn't have to wait very long before I was seen by Dr. Kaiser. The consultation was very quick and thorough. I was very satisfied with the treatment I received."
"I started having GI issues at the end of 2020 (throbbing chest pain, regurgitation). I spent almost a year with a different GI doctor who was having trouble diagnosing my condition. I was prescribed different dosages of medications and nothing was working, I was beginning to worry that we would not figure out what was causing my pain and it would be something I would have to learn to tolerate. It was disrupting my sleep, causing me significant pain during the day, I couldn’t eat most foods and was losing a lot of weight on a bland diet. I met with Dr Gluskin in Fall 2021 and he took a linear approach with ruling out various conditions. After a few different procedures, we were able to come up with a diagnosis and a medication that has been actually working for me. I am able to eat most foods, get adequate sleep, and feel a lot better than I did a couple years ago. Dr. Gluskin truly gave me my life back and I am so thankful for him!!"
"I’ve been a patient of Dr. Gluskin for about two years now. He’s performed a couple of procedures and resulted in good news. He’s advised me on dietary changes and to get more exercise and more quality of sleep. This is definitely been helping my digestive issues. The key is to make time to eat! Recently had a follow-up and the staff was great! Dr.Gluskin is kind, friendly and was happy to see my improvement! He’s always kind and compassionate with me. Definitely recommend!"
"I have been a patient of Dr. Lee and his excellent care for over 20 years. He always has time for my questions. His staff is also excellent and available to talk with by phone. It is a pleasure to come to his office!"
"Very nice staffing. Of all my colonoscopy, I have to say this was the best and very quick. Dr. Lee was awesome and touch base on my procedures. Would highly recommend, your service. God Blessed you and the staff."
"Dr. Robert Clark was very professional, but yet very down to earth in his approach. He made sure all my questions were answered. And I was very reassured by his open, pleasant personality. He has been in the practice at the office 9 years and I have been an established patient with this office for over 25 years and that speaks volumes to me."
"I would and do recommend Dr. Chadha to others. He discovered a tumor in my abdomen five years ago, recommended an oncologist and a surgeon. I received wonderful care including six months of a target therapy drug to shrink the tumor in order to protect my other organs from damage during surgery. Dr. Chadha exhibits the most important qualities of knowledge and compassion. He is a credit to his profession, and a lifesaver to me. Sincerely, Arlene (Lee) Marisi"
"Dr. Lee is amazing! From arriving at Hinsdale hospital in 2012, I was finally diagnosed with problamatic pancreas divisum. For 10 years he was kind and caring with all the health problems I encountered. I've been told most GI doctors are very caring; however, Dr. R. Lee is exceptional. Thanks for taking good care of me!🙂👍"
"Dr. Matthew Horowitz was very caring doctor also the staff there were awesome and also the doctor they were very helpful I had down the throat and up the an upper rectum very caring no pain at all I was knocked out sleeping if you looking for a good staff and doctor need to check him out also the staff they are amazing they also check up on me and see how was doing . also saw the doctor before the procedure and after the procedure didn't find anything I was cleans as a whistle thank God for that praying does help so if you have to have it done get it done they told me I have come back in 7 years for a recheck up the only thing will hurt is the bill from the doctor that's the bad part of it.lol"
"Dr Robert Janda has been treating me for over a decade for my Barrett's esophagus. He's an excellent Gastroenterology Specialist and very professional but I also like his calm demeanor and bedside manner. He's very patient and answers all my questions."
"Was very pleased with the care I, received from all the Nurses. Dr. Robert Janda is always very Professional, He explained all the procedure and all I need to do for further care.I recommend Dr.Janda very highly."
"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 have been a patient of Dr. Lee for almost two decades. Late onset crohn’s had us all baffled. Dr. Lee tried every trick Dr Internet knew and a few more but it took old school exploratory surgery to prove him correct. He’s quite knowledgeable but not one of those annoying know it all’s. I’ve seen him reach out to colleagues so the both of us can feel assured. He’s fun and easy to talk to and will take the time to ensure you understand with out needlessly using big words just to get rid of you. I could easily call Dr Lee a friend and have no problem trusting him with my life. I have also found his office staff and nurses as helpful and attentive. I and my wife have worked in healthcare all our lives. I’ve tried not to but it just seemed to draw me back. My first part time high school job was maintenance at a long term facility, then U.S. Navy Corpsman, combat medic, every department but billing in a hospital and am still a field service engineer for medical imaging equipment for over forty years. I might know what I’m talking about. I almost don’t dread my colonoscopies. Dr Lee is highly recommended."
"I have been a patient of Dr. Lee for approximately twenty years. He came highly recommended and I was initially referred to him by two primary care physicians for a unique virus condition, which he was able to cure. Much to my satisfaction, I have continued to work with him over the years for standard preventative adult care procedures. Despite sporadic contact, he always recognizes me and knows exactly who I am. He provides sound advice and always follows up on whatever information is necessary for my continued good health. Both he and his office staff have been a pleasure to deal with and I hope for their continued success."
"Dr. Robert C. Kaiser is a very Excellent Doctor. I've been a patient of his for about 10 years or more. He is very through Doctor and has a wonderful bedside personality ❤. He's a blessing to have him on my medical team."
"i have never met such a great team of doctors, NPs, and nurses before. everyone is so happy all the time and make sure you’re 100% comfortable. very low wait times and very smooth operation. thank you to especially dr. lee, NP jolene, nurse maria, nurse crystal, nurse nicole, and nurse nikki. absolutely wonderful staff and clinic. keep up the great work!"
"Dr. Robert C. Janda is a really great Dr. He listens to you, questions you and tries to get down to the root of the problem. He is very professional and thorough. He does not rush you. His staff is very proficient and helpful."
"Dr. Robert Janda, Gastroenterologist, is simply at the TOP of his field. In fact, probably ANY medical field when all important considerations are factored in. • His knowledge of his profession is comforting. • He has a terrific demeanor, disposition, and personality. • He is perfectly willing and interested in discussing any concerns and questions presented to him. • Dr. Janda - and his staff - are great at making an awkward and uncomfortable experience feel far less “threatening”. • clearly, I have only good to say about Dr. Robert Janda and while he was originally a referred physician/specialist for me, I unofficially refer or surely recommend him for you. It’s a pleasure to be able to write a review of this nature for a doctor rather than feeling a need to write something cautionary and unflattering. I LIKE Dr. Janda and I suspect you will also."
"Dr. Lee has been my gastroenterologist for close to 20 years now, and I have no intention of changing that. Not only is he knowledgeable in his field, but he loves his work, and it shows. His disposition is always cheerful, he answers questions with no sign of impatience, and puts me at ease instantly. To me that is so rare in the medical world. There is no hint of condescension, yet he takes his job seriously, and when I leave his office, I always feel better than when I walked in. I highly recommend Dr. Lee. ,"
"1) very professional staff 2) extremely friendly and happy 3) very punctual 4) explains procedure before and after 5) always reassuring and polite 6) simple procedure 7) Doctor was awesome 8) Anesthesiologist did a great job 9) Office was extremely clean 10) very very convenient"
"I have had absolutely positive experiences with Dr. Lee…he thoroughly goes over your health concerns & problems & gives u peace of mind when u r going through really hard times w/gastrointestinal problems that affect everyday life….he takes time & helps make positive decisions & choices with you which changes the situation & makes it hopeful with a smile 😊 I know that I am in good hands with a caring exceptional doctor."
"Dr. Lee has taken great care of me for about 15 plus years. My medical conditions are quite challenging at times. Dr. Lee is always there for me. He is very intelligent and thorough with lots of year’s experience."
"Dr. Lee has always been wonderful, I've been a patient of his for years now and he always explains everything that is happening in great understandable detail. No one could go wrong by having him as your Doctor."
"Dr.Lee has been my Gastrointerologyest for over twenty years,, and also treats many of my Family members and friends. Do to His careful monitoring of my Gerd issues , He caught a change in my Esophagus and through His quick actions I was immediately treated for early stage Esophageal Cancer , with great results . I'm Five years post operative and Cancer free, this outcome was only do to His quick action and supervision of my treatment."
"I've been under Dr Lee's care for 20 years now. Reason? He takes the time to really know his patients and is genuinely concerned for their well being. Plus, he remembers who you are...it's not a cold and impersonal experience. I don't feel like a number in his care. I feel valued. Thanks Doc! You rock!"
"Best doctors office I have been in , in a long time. Very relaxed atmosphere and the staff is very friendly. Wouldn’t go anywhere else!! Dr. Lee is very personable and straightforward. He definitely knows his job. So glad my GP recommended him."
"I would recommend Dr. Lee and the whole practice. I have seen Dr. Lee and Dr. Janda for many years. My son goes to them and my daughter has an appt this week. Dr Lee also has a very good sense of humor."
"Dr Bernsen is a phenomenal doctor. I am speaking as Dr. Bernsen’s patient but also as a medical provider. I came to see Dr. Bernsen for second opinion after seeing someone else for 7years. I was hesitent of leaving my previous doctor because you get attached. However, I knew I was not getting the symptom relief or quality of life I deserved. My ulcerative colitis was simply not treated. Now, boy am I thankful I saw Dr. Bernsen. For the first time I saw a light at the end of my tunnel. If anyone has moderate to severe ulcerative colitis, you know how bothersome signs and symptoms get, how drained and hopeless you can feel. Long story short, you do not feel yourself. Can’t enjoy food, have normal bowel movements, plus your social life, mood and sleep is affected. I’m thankful because Dr. Bernsen took care of me. He offered me medications my previous provider never mentioned. And after 1 tablet of prednisone Dr.Bernsen prescribed, my symptoms improved drastically. I can not say enough of how thankful I am of getting my life back. All my ulcerative colitis signs and symptoms resolved after incorporating a new treatment plan. I can eat normal again, have my energy back, and I do not need to worry about having a bathroom close by. A very grateful patient, A.Opiela"
"(Translated by Google) If I keep coming back to that clinic, it is because he treats me very well, in every sense of the word, he is a great doctor, and I really highly recommend him. (Original) Si yo sigo regresando a esa clínica, es porque se me trata muy bien, en todo sentido de la palabra, él es un gran doctor, y en verdad lo recomiendo muy fuertemente."
"This was my first colonoscopy experience, but at 57 I knew I needed it done. I had some trepidation going into the whole process, but mostly uncertainty. But after leaving Dr Adler's office I was pretty amazed at how easy it all was. From the time I walked in to a warm and genuine greeting from one of the nurses (I think her name was Jackie) to the time I walked out a couple of hours later, it was stress-free, painless, and comfortable. Including the front desk person and Dr Adler I believe there were five people I interacted with during the procedure. Each of them was very helpful, making me comfortable and putting my mind at ease. When I was brought into the room for the procedure, the nurse anesthetist (Nikki or Nicole) explain what she would be doing, and after administering the anesthesia I think I was out within 30 seconds and "came to" after a very deep and satisfying sleep. There were no complications during the procedure, images were shown of a few polyps that were found, and I was told that I would get news of the test results soon afterward. While some people have reported being a bit loopy afterward, I felt no odd side effects and had a pretty normal day from there on. They asked if I wanted a follow-up "well-being check" which I declined, since everything had gone so well. The office did follow up with a phone call with tested results in a reasonable time. In summary, my experience with Dr. Adler and his staff was really "first rate.""
"I normally wouldn’t use social platforms to reference Doctors. Always refer to the actual medical references and resources. I had a procedure done at his office it went very better than I thought. His staff was friendly and helpful and professional most of all it was virtually painless. I would have given 5 stars but the nurse who prepared me for checkout abruptly pulled out the IV needle while my arm was south and not resting by my side I had some bleeding. Otherwise, it was a good medical experience. He does have 35 years of experience and is from the original Ingalls hospital aka The University of Chicago."
"Dr. Lee explained very clearly and slowly the gallbladder procedure (ERCP) he was going to perform. He then did exactly what he said...and then met with my family in post op to review the gallstone-removal results. He is the REAL DEAL...cool, calm, collected. His emergency surgery skills made the following day's gallbladder removal a huge success."
