"Dr. Bajaj and staff were amazing. Everyone was professional, friendly, and knowledgeable. I have been seeing Dr. Bajaj for about 20 years, intermittently. He has always been a doctor worthy of my trust. His demeanor and bedside manners are impeccable."
"One of the most thorough and well run medical practices I use. I have a few health issues and for my stomach issues I use this group. They really try to get to the root cause of my stomach issues by testing and trying different approaches and lots of meaningful communications from a great well coordinated team of highly qualified Drs. And Nurse Practitioners. I always know what’s going on next and why we’re doing it. I wish all my different Dr. Groups were run as well as this one is. I have the one thing that a Dr. Really needs to earn, and that’s - my confidence. I am confident they will get my issues resolved."
"My experience at this location is outstanding. The staff are there to greet you and answer any questions you may have. They are very professional and the space is so clean. It make you feel at ease and comfortable. My doctor Baja is the best. I trust him with my life. He is always on top of things. Dr.Baja will actually call me at home to see how I am doing He will call me to let me know about my test results I never had a doctor that would do this. He is so intelligent, professional and he tells you everything you need to know. He informs you what he will be doing next to find out what is actually going on with my health. Dr Baja is just a great doctor and I’m so happy to have him for my doctor."

"I highly recommend Illinois Gastroenterology Group. I have been a patient of Dr. Arndt for many years and at my last visit I saw the Nurse Practitioner Lauren Smith. I am extremely satisfied with both of these medical professionals; I feel they listen to my concerns and ensure they provide the best care and follow up possible."

"Needed to have a colonoscopy performed, and had no idea what Dr to use. I harbored some concerns as the last colonoscopy I had (some years back) was not a "good experience" at all.Friend recommened Dr. D'Astice. Contacted his office to schedule. Thus began a wonderful experience dealing with 3 ladies in his office, Michelle, Tammy& Yolanda. Over the next 2 1/2 months, They worked with me on the phone, answering questions and preparing me for the prep. Everyone treated me with respect and dignity, and the procedure went well. Dr. D'Astice and his entire staff (including the anesthesiologist) were great. A hearty Thank You to all."
"I would like to thank Dr. Imad Elkhatib for taking care of me, he is so professional, caring, and kind and patient, and always spent time explain my questions with patience. Dr. Imad Elhatib was recommended to me by a famous Hospital Physician during my stay in the Hospital., I am so happy I made a great choice and so lucky to see Dr. Elkhatib in several years, he is the best GI Doctor that I have ever had."
"Lauren, Dr. Arndt's P A was going to tell Kim Dr. Patel's nurse to call me to set up an appt. for a EGD. So far I've heard nothing and it's been a few weeks. I suppose I have to call Dr. Patel's office to see what happened."
"Service was great 👍"
"Dr. Muscarello was able to diagnose my husband within 15 minutes of his examination. Very kind, caring, a great listener and is sympathetic to his patients needs. We would highly recommend him to anyone."
"This was my first time there & it was wonderful. The nurses were all polite & made sure you were comfortable. Dr. Bajaj is also wonderful. I have been seeing him for several years & he is by far one of the best doctors that I have ever had. If I could rate more than 5 stars, I would. Thank you!"
"I love Dr.Bajaj, He is so kind and very thoughtful, answers all your questions."

"Dr. Bajaj is the best doctor. Very knowledgeable with a fantastic bedside manner. He always listens to what you have to say."
"I have been going to Dr. Bajaj for yrs. He was my mother's gastro doctor first. He found her tumors when no other doctor could. That is why I choose him to do my own care. He is polite, informative and always follows up to see how ones progress. His staff at both location are great. I highly recommended doctor Bajaj even my own pcp gives him always positive reviews."

"Dr. Bajaj is very knowledgeable, caring and kind! Has an excellent and professional bedside manner! This office made me very comfortable and had me at ease for an uncomfortable hitting the big 50 procedure. Everything was so organized, quick, painless and can’t say enough about the staff, nurses, and receptionists who were pretty amazing as well. I also want to mention that the office called me the following day after my procedure as well as Dr. Bajaj personally to see if I was ok and if I had any questions. This doctor and his office is highly recommended!!"
"Dr. Muscarello was referred to me by another doctor whose opinion I value and trust. When I asked “If you needed a GI doctor, who would you choose?” His response was “Dr. Muscarello”. I asked him why specifically and his reply was that he is just a really excellent doctor. I have had Crohn’s Disease for 17 years. I had a bowel resection in 2003. I have seen 4 doctors over the course of the last 17 years. I switched to Dr. Muscarello and it was the best move/decision I could have made. He is (by far) my favorite out of all that I have been with. He is so intelligent and knowledgeable. My previous GI doctor was okay (at best) but I had no idea what I was missing out on until I met Dr. Muscarello. He listens, he cares, he wants to help, and he’s very intelligent. You will see that the first time you meet with him. I feel as though I am in good hands with Dr. Muscarello. The staff in his office is excellent. Every time I have needed to speak with a nurse, they take the time to listen and explain. The entire experience with Dr. Muscarello and his staff has been nothing short of amazing. I HIGHLY recommend."
"Dr, Bajaj was a great help to me. The GI team are professional and kind. The issues that I have had for years are finally being addressed. Thank you Dr. Bajaj and team!"
"Highly recommended"
"Nice and caring"
"very competent and knowledgeable in his field."
"Dr. Ajay Bajaj performed an upper endoscopy on me Thursday, October 29 at Advocate Good Samaritan Hospital in Downers Grove. From the moment I entered the hospital I was well taken care of by the most awesome group of caregivers. Megan was my admitting RN, Carmen was my procedure assistant, Alex and Stacy were my amazing procedure RN’s, Bill was my recovery assistant, Sabrina was my awesome recovery RN and then there was my amazing physician Dr. Bajaj. from the first moment that I met Dr. Bajaj at his Oak lawn office he made me feel totally at ease. Dr. Bajaj is very detailed in his instructions to you about what you’re going to go through and or experience. When I had a question just one day before the procedure, Dr. Bajaj returned my call in a very timely manner putting me at ease. Upon my discharge I was given complete detailed easy to follow instructions and callback numbers if I had any questions. Thank you Dr. Bajaj for taking such good care of me. I pray that the most high God continues to bless your hands as well as your mind."
"Dr. Muscarello is the BEST! He is the only gastroenterologist my family & I will see. Dr. Muscarello is very professional, explains everything, takes his time with you and is friendly."

"Very caring and thorough doctor, amazing bedside manor. She took the time to make sure I understood everything. Wish I would have found her years ago."
"Great bedside manner, very funny and informative."
"Good experience with the medical staff. Dr. Kwon was professional and caring."
"Sure you might wait in the waiting room. But it is well worth the wait. My experience with Dr. Charles Berkelhammer has been nothing but fantastic. He listens to the complaints, asks questions and forms his diagnosis. That might call for procedures to be done. After all oil f that he takes time to explain and answer your questions."
"Everyone was kind, helpful and thorough. Procedure started on time. Was out in exactly 1-hour as the nurse stated the day prior. Great experience!"
"The quality of the care is impressive."
"I was treated by Dr.Berkelhammer and Sandra Bernklau and they took care of me and my problem quickly and professionally. Very nice people and took time to explain my situation."
"The quality of the care is impressive."
"Very friendly and professional place."
"They are excellent and up to date on procedures and health related. Very great and trustworthy!"
"Scheduling took back and forth phone calls for a total of 9 days to get an appointment. There was never a time that someone actually picked up the phone. Then it took approximately 2 days to get a return call and it was mostly when I stepped out. Then another 2 days of waiting for a callback. I almost switched to another doctor. But from he moment I stepped through the doors for my appointment I only experienced kindness and a perfectly run office staff. I was very impressed with everyone I encountered. All showed professionalism. Dr lue was everything I hoped for in a physician. Glad I did not switch after all I opted for Osmoprep because of a very bad experience with the other. Projectile vomiting, etc. found out it costs between $200 and $300 for the 32 pills depending where purchased. Called my insurance company and they gave me a phone number for doctor or staff to call directly. Explained my situation and they said they could make me a tier 3 which would then cover 30% of the cost. scheduler refused my request by telling me if they did that for me then they would be spending their entire day doing it for everyone. Really? How many people actually need the Osmoprep. I was very disappointed in her lack of empathy. I feel if I could have talked to dr lue directly and explained it to him he would have made the necessary phone call to save me the money."
