Dr. Atallah is the best! A week ago today, I had a procedure I was dreading- an endoscopy. But with Dr. Atallah, it was a relatively quick and simple procedure with a positive outcome. He is always so pleasant but thorough to be sure we have searched all possible options. If you need a GI specialis, I highly recommend him! Dianne Allen-Rieck read more

I had an extremely poor experience with Dr. Lalehzari's office. I can't believe that a doctor's office can function in such an disorganized way with such poor communication. Dr. Lalehzari's office facilitated ordering a specific lab test from a lab company for me. The lab test took over three weeks to be delivered to my house. When it arrived, it was the wrong test. I don't believe the long wait was this office's fault, but I do believe receiving the wrong test was an error from Dr. Lalehzari's office. Via email, I was sent the lab results from another patient. I know it was a mistake, but that seems like something you would want to double-check. I scheduled a telehealth visit with the doctor over two weeks out. With less than 24 hours' notice, her office called and asked me to move up the appointment by one hour. I called back, and no one was available, so their answering service answered. I told the person at the answering service that I could not make the appointment one hour earlier. I was told this would be relayed to the doctor. It was not. I was then told that I could make an appointment another two weeks out, but that they would put me on a wait list on a sticky note. In my patient portal, there were links to files. Two of the files were from a completely different doctor. I asked this office about these files, and they could not give me a reasonable explanation and told me not to worry about them. The amount of errors, miscommunication, and terrible service makes me wonder how many other things are going on behind the scenes that I did not see that are mistakes, errors, or a lack of care? To say I am extremely disappointed with this office and how they operate is a massive understatement! read more

Very professional, thorough, Dr Flicker always listens very attentively and really "hears" what I have to say. I highly recommend Dr Flicker. His staff is always professional, kind, and considerate. I highly recommend Dr Flicker. I'm always able to depend on Dr Flicker for outstanding healthcare. read more

The staff and Dr Dhamija did everything they could to take care of me in a timely fashion. I am appreciative and it could not have been better. read more

I was referred to Advanced GI by my PCP (I'm a 35m). I was able to get in pretty quickly with Dr. Manish Dhamija and ran through my symptoms. Due to a positive FOBT result. Dr. Dhamija got me scheduled for a colonoscopy where we removed 3 polyps, 2 of which were precancerous. My overall experience with Advanced GI and Dr. Dhamija was great - the office was very kind, made quick appointments, had great instructions for prep, and gave results when they said they would. Dr. Dhamija was precautious, friendly, and thorough and I'm glad I will be seeing this group again in 3 years! read more

Two doctors, Flicker and Lalezhari, gave seriously substandard care and I had to leave the practice to get treated for H. pylori. Also two bad experiences with the lab they use, ADT. Avoid if possible. read more

As a clinician I have heard great things about Dr. Atallah from several of my patients over the years, so when it came time for me to see a gastroenterologist I knew exactly where I wanted to go. His practice not only did not disappoint, but far exceeded my expectations. I felt respected from the moment I walked in; the nurse made me feel seen and heard instead of rattling off questions about my health history and behaviors. Dr. Atallah was strikingly warm, personable, and incredibly clear in his explanations about diagnosis and procedures, and importantly I did not feel the slightest hint of condescension. He was attuned to all the sensitive factors that are involved in the gut - mental, emotional, diet, etc. (this can be difficult in my experience) while also clearly staying up to date on the research and diagnostic & intervention development in this field; during our conversation he referenced a study that came out only last month, and an FDA approval for a genetic test that was approved just two days ago. Finally, I could tell he takes great care to prevent unnecessary costs for patients by utilizing ambulatory/outpatient surgical centers instead of hospitals when one's insurance allows it. It really feels like Advanced GI has worked hard to provide the best possible care for their patients by remaining independent, and it has made all the difference for me. read more

First visit with Dr Lalehzari was very disappointing! Although she seemed very intelligent, she could not give us the courtesy to answer our questions. She was in a hurry to get to next patient, but did not take into consideration it is not easy for us to get there with our son and we had travelled for an hour an a half. Maybe, it is better to know now, because she was inconsiderate and did pick her nose three times while speaking to us and we will not be returning. read more

Worst doctors I have ever been to. You wait months for an appointment and then Dr. Lalehzari did not even take 5 minutes to speak with me for this appointment and listen to my concerns. What a waste of time. She just said keep taking your medicine and walked out. I had a televisit with Dr. Atallah several years before this and he was just as bad. Worst doctors don't waste your time. read more

Complete waste of time. Dr. Laleahzari talked to me for 10 minutes, rushed me off the phone and then diagnosed me and prescribed me medication that was insanely expensive. AS SOON as I saw another doctor, they were able to help me and put me on the path to healing. This facility is a complete waste of time and money. When I was taking medication that was making me sick, I told them and their response was literally "I don't know what you want us to do". UNBELIEVABLY IRRESPONSIBLE! This is not a medical care facility. They are just trying to make money. These people should not be practicing medicine at all. They treat you like you are burden and in order to get any response from them at all, you have to almost harass them. Absolute worst doctors I have ever been too. If the people there are not ashamed of how they treat people looking for help and healing, I'm ashamed of them. God awful. Stay away. read more

I have never felt so dismissed by a doctor in my entire life. I was seen by Dr. Manish Dhamija and the appointment lasted for all of 5-10 minutes. Brought up multiple issues but only one was addressed. Continued to tell me that what I eat isn't an issue - but didn't even ask what I eat on a daily basis. Only asked what type of fiber I take - sorry I don't have the brand name off the top of my head, didn't know that was so important. I had to nearly stop this man from leaving the room to ask follow up questions. He immediately went from take fiber / miralax / water to do you want a colonoscopy? Well, doctor, do you think I should get one?? How am I supposed to know? Didn't even attempt to rule out other issues (like IBS/Celiac's) before asking about colonoscopy. Do not recommend coming here. My concerns were not addressed, just dismissed. This appointment made me feel like I'm crazy and just making up my issues. read more

Best of luck trying to get an appointment. I had a referral from my PCP for Michael Flicker. No one answered the scheduling line for an entire week (wildly unprofessional!) and there was no voicemail to leave a message. I then tried to book online. Flicker had no appointments open for 90 days, which I get (GIs are really busy these days), but the calendar wouldn't go beyond 90 days! With no way to reach these folks, I gave up and found my own GI elsewhere. Really a bad look for this practice. read more

This was one of the worst experiences I have had in doctor- patient care. The doctor I saw, whose name I will not mention entered the room carrying a laptop and did not make eye contact with me and began firing questions and typing. As I was answering sensitive questions and scared, I stopped answering at which point the doctor finally looked at me and I said, "You need to understand. I am scared." The doctor slowed down for a moment and talked to me like a human before returning to being a computer like person. I left feeling unheard with a prescription. Is this what medical care is coming to? read more

This office is so unorganized, doesn't follow up if they're missing something they need. Knowing I had a few weeks until I needed my next infusion, they didn't submit a PA until I followed up asking. They then said well we don't have all the paperwork from previous doctors... well then ask!! To my knowledge they did send it. Turns out their fax number is different online than the one provided over the phone. Dr. Atallah was also shockingly incapable & didn't listen during the whole appt. I switched immediately after I got the infusion I needed. There's much better GI's in Chicago! read more

The office staff and their third party billing department are completely rude, dismissive, and don't seem to care if you have a good experience. Would never recommend. read more

Outstanding GI doctor, very responsive and knowledgeable. He's very kind, a good listener and offers new solutions which have been very helpful to me. I'm very glad that I found Dr. Atallah. read more

My overall experience with Dr. Manish was positive, however my experience has become negative after receiving couple unexpected bills from the doctor's office. If you have a colonoscopy, expect a separate bill for facilities charge, professional charges and anesthesia. It's negligent that the office does not explain all of the expected separate bills you should receive prior to having the procedure. Beware what you're getting yourself into! read more

I was seen immediately by Manish Dhamija, MD via virtual visit after referral from my PCP recommended specialist. Following this visit, I received instruction to undergo a CT scan. This required several hours off of work. The administrative team communicated normal results. The office made no attempt to schedule a follow-up to continue care. From that point, I received no further communication until I insisted on medical records release to move care only after persistent emails and calls. They then recommended I come in for an in-person visit but did not offer availability. Anemic follow-up but had no problem billing insurance to the full extent. Would not recommend. read more

I honestly was hoping to have been one of the people who left 5 stars from an amazing experience but that has been far from the case. Last Monday I got a colonoscopy w/ Dr Carl Atallah from Advanced GI and 2 weeks prior we had a virtual consultation. This review is absolutely written with frustration and disappointment from my appointment. And I never received any clarity as to why my procedure didn't go as planned due to the doctor and doctor's office not responding to my request to speak to the doctor to give feedback and ask clarifying questions.   Now, I will say that everyone was very nice and hospitable last monday during my time there, which I appreciate, even when we felt rushed out after I woke up. But if NO ONE was going to actually listen to my needs, what was the point of this procedure and the 3 day sacrifices I made? My boyfriend and I took off for work and paid for 2 uber rides for this only to leave more disappointed than when I arrived.  When I had my virtual appointment I stated that I have been dealing with a chronic anal fissure since November of 2021. I stated that I have had a hemorrhoid for years now but for some reason last winter I got a really bad anal fissure that just NEVER healed. I stated that I have tried Prep H multiple times and it did not work. Prep H actually burns now when I use it, when it didn't before, as there wasn't an anal fissure present. I stated that I have done sitz baths and they have not worked. I stated that I had a prescription that only had 3 refills that helped with the pain but not with the healing because the hemorrhoid was stopping that. I stated that I wanted to get the hemorrhoid banded so that the anal fissure could finally heal as it keeps get reactivated when I move my bowels due to the hemorrhoid being an obstruction. I was very aware of my body and knew what I wanted/needed to be done in order to have peace of mind and get back to my normal routine of life. I have gone -80 sick hours at my employment due to calling out of work over the year from the agonizing pain.  Every nurse I spoke with I told them the same thing. I had very high hopes that I was going to be waking up on Tuesday morning pain free. I had very high hopes when I went into work the following day,  that I would be able to for the first time in over 8 months not embarrassingly use my donut cushion to sit on all shift. I can barely sit right now at my desk to type this review as I am in burning pain.  My virtual appointment now feels very misleading as I was under the assumption that I would be having a colonoscopy with banding. As I gained more and more consciousness from the anesthesia, on my way home, I began to realize what happened, which was nothing. And then I recall as I was being discharged, not only was I being told I have a hemorrhoid but that no anal fissure was seen, but also wasn't being looked for was a whirlwind of confusion. For it to only be followed up with, "use Prep H, take a sitz bath...maybe I can get you a prescription...if the problem persists we can band the hemorrhoid". It was as if NO ONE heard or listened to anything I said. This has been a problem for over a year now and ALL of that was communicated. I also was given discharge paperwork with personal information and images of another random patients colon and I don't know if that other patient had mine. I called last Tuesday, the following day of my procedure and sent a follow up email on Thursday. It is now the following Monday and I have not received ANY communication from ANYONE. I find this whole process to be disgusting and negligent. I would NOT recommend this office nor Dr Atallah. NO banding and NO prescription. An absolute waste of my time but of course I'll be expected to pay any copay required for this unsuccessful and incompetent experience. read more

Dr Atallah and his staff are just great! He provided excellent diagnosis, treatment, care and follow-up with my recent procedure. His staff was kind and more than willing to work with my busy life to get me in for an appointment. Maria G 'The Scheduler' was patient, helpful and thorough. I really felt cared for as a person and would reccomend Dr Atallah and is staff without reservation. I would give him 10-stars if I could! read more

Wonderful staff, and through, considerate, knowledgeable care by Dr. Flicker! Thank you. read more

I saw Dr. Berger and he was wonderful. Very informative, took time to discuss everything in detail and answered all of my questions. It was a pleasant experience and I would highly recommend him. read more

The doctors and their staff are very professional and courteous. Dr Atallah was very down to earth and took his time explaining everything to me. He was very knowledgeable about my issues, and prevented me from serious health problems I could had in the future. I can not express my gratitude in words I have for Dr Atallah. Advanced GI is a 5 stars practice!! read more

Thank god for Dr. Flicker. I was having multiple idiopathic pancreatitis attacks and was in and out of hospitals over two months. When Dr. Flicker was assigned to me was when things were finally getting sorted out. He was able to identify that it was my gallbladder that needed removing. I'm now 4 days pain free after having the surgery. Dr. Dallas performed the surgery to remove the gallbladder laparoscopically. I'm so very blessed to have had Dr. Flicker as my GI when I went to Illinois Masonic Hospital, otherwise I might still be experiencing biweekly pancreatitis. If you've never had an attack, pray you never do! Thank you Dr. Flicker, so very much! Sincerely, Derek Setterlund read more

Dr Atallah is an exceptional physician. Very professional and highly qualified. I would highly recommend for someone dealing with GI issues.

Couldn't recommend any higher. Wonderful doctors who truly care about their patients.

Dr. Flicker is excellent. After a year of suffering while being told by a different doctor that my condition was chronic and untreatable, I went to Dr. Flicker. Dr. Flicker examined me, listened to me and recommended a different form of treatment. I slowly improved over the next few months and then returned to full health. I have been totally healthy for three years since I have been under Dr. Flicker's care. It is not an exaggeration to say Dr. Flicker gave me back a normal life. read more

I had the worst experience EVER and I didn't get a chance to see the doctor because I decided to leave after how I was treated by his office and clinical staff. Let us begin by how rude office staff are when answering the phone and how they lack any sort of warmth when greeting patients. Then the clinical staff are clearly disengaged and more interested in chatting with their friends at the reception desk. When called the PA couldn't be bothered to show her face so I had no idea if it was clinical staff or some spiritual being calling my name from beyond the door. When I peeked my head into the corridor there she was chatting with reception staff. She didn't greet me she just escorted me to a room. While I'm sitting down she just fiddles with the computer and had random awkward pauses between questions. Didn't even ask why I was there... Once I'm done with this awkward encounter I am seated in another exam room where I wait and wait... in there I can hear, as clear as day, the doctor in the next exam room carrying on a lengthy personal conversation with a patient. Glad to hear they both like to "party." While in this room I have reached over an hour of waiting. Being a provider in the healthcare field myself I knew that I couldn't trust that I'd be getting good care and I ,honestly, stormed out and told the receptionist that I better not be charged because this is RIDICULOUS! Until this provider make changes to their staffing and prioritizes client care I suggest that you consider another referral. read more
