"Well oiled machine and friendly staff. For an all the horror stories you hear, they made it pleasant. Highly recommend! Thank you Dr. Fern and staff!!❤️"
"The facility and staff here are excellent. I cannot recommend them any higher. I have seen Dr. Thyssen twice. He is always pleasant and very professional."
"Dr Root and his team were willing to inform me of details, and answered my questions patiently, and followed up on question they needed to check on with other records. A good experience overall A+."
"The Doctor and his staff all worked very well together to make my procedure as pleasant an experience it could be. Highly competent group, top to bottom."
"Dr. Root has been such a help to me. After years of frustration GI doctor visits where I felt the doctor did not care about my situation and prescribed the bare necessity to treat the pain and not the problem. After switching over to Dr. Root I have been met with such kindness and help with my problems. I feel that he is a doctor that really cares and spends time with his patients and listens to them and their needs. He’s gone above and beyond with helping me with my issues. Thanks Dr. Root!"
"Dr.Root is awesome, he’s friendly and the office staff are even wonderful too. He’s definitely a doctor I would suggest. He’s patient and answers all your questions patiently."
"Excellent doctor excellent care. My procedure was thoroughly explained to me. I had been there before. And she remembered me. That really made me feel at ease. You need"
"Dr. Erik Thyssen is absolutely the most caring, compassionate doctor I ever had. I LOVE HIM, the staff there was EXCELLENT. Thank you all for a very pleasant experience."
"Dr Thyssen and the surgical staff from AEC were very efficient and worked together as a very pleasant team. I would have given 5 stars except my phone call to SIG a week before the colonoscopy almost made me cancel. I called SIG to get a better clarification as to the pre-colonosocpy diet. Whoever I talked to seemingly got annoyed with me asking questions and I was told to stick to no seeds or I they wouldn't be able to do the procedure. How does anyone know they consider bananas to have seeds unless it's clearly stated. I found a diet sheet online from a credible university and followed that. Please include a diet sheet for patients to follow - people's interpretation of peel and and seeds vary. AEC didn't call me until the day before the case to pre-register me. For those two items I'm knocking off a star but the surgical team were the best."
"I never feel rushed in my appointments like I do at some of my other doctors. He is very thorough and you can tell he cares about his patients. 5 stars always!"
"Very efficient office. From making appointment to check in to wheelchair ride out Nurses very nice! and attentive. Dr Singh very courteous answered questions! All staff very good!!! 10 stars if I could!!"
"Clinical excellence + compassion and genuine caring wrapped up into one human being is the best way I can describe Dr. Thyssen. He is a skilled GI doc who listens, asks questions and works with you to make sure you are getting great care. I am a nurse and really picky about the doctors I choose for myself and my family - Dr. Thyssen is fabulous!"
"Outstanding performance of the colonoscopy. Dr. Thyssen showed care, compassion and competence. He is supported by an excellent , experienced staff throughout the process."
"Everyone on the staff is dedicated to making sure the patient is cared for from the moment they walk in the door until the moment they are taken to their car by wheelchair. Dr. Thyssen is one of the best doctors in St. Louis and I am in good hands with him."
"Everything from the check-in to discharge was pleasant and professional. I think that Dr Singh is wonderful. I have seen her several times. I would especially like to say that Sarah, Dominic, and Dominic who cared for me before and after my procedure were wonderful.."
"Dr. Singh thoroughly explained what was involved with my procedures including risks and potential complications. She was very easy to talk to about my concerns. Procedures were performed effectively and efficiently without any problems. I am very satisfied an would recommend her for her expertise."
"Doctor Root was Awesome today. I was shooting on see my mom & sisters doctor Aman Singh but very busy. I chose first available and It worked out. Dr Root is a young guy to keep an eye on me for the rest of my life. Things happen for reasons. Since I couldn’t see Dr Singh I got Dr Benjamin Root and I’m happy. He will be my doctor thank you."
"He performed my upper endoscopy and made the whole process quick, easy, painless and free from the scaries. His whole team has been wonderful and so helpful."
"This facility runs like clockwork. The staff is friendly and professional. They make sure you are comfortable throughout and make you feel cared for."
"When Tonya first took me back for my colonoscopy, I was concerned. She was not friendly or accommodating. She was harsh, hurried, and appeared very annoyed that I was there. After that introduction, the people got much better. The rest of the staff were friendly and nice. Dr Thyssen is always pleasant and I do have faith in his procedures."
"Dr Thyssen and everyone one his staff we welcoming and caring. I got lots of assurances and pats to comfort me. The Dr and all his staff are proficient and professional."

"Well the nursing staff is fabulous the place is welcoming and my doctor was wonderful informative the anesthesiologist was wonderful it was just a great place to go when you have to do this you're in and out they move quickly but not too quickly it's definitely a five star"
"Dr Singh did 2 procedures that were non-eventful, just as I like them. The team that she has working with her were both caring and efficient. They joined me in singing “Goodnight Sweetheart” as I was going “out for the count “. Lol. After the procedure Dr Singh came to speak to my husband and I to explain what she found, and what she did. I appreciate her candor and willingness to discuss. I also like that when I left there, I had all the info, plus pictures of areas that she either removed polyps or did biopsies. Many Drs don’t provide that info immediately like her, and the other Drs in that practice do."
"The entire staff was very very professional and friendly. Dr Weinstock went over my pictures with me and provided a copy. I love this medical office."
"I’ve had two procedures at other facilities and the level of care and friendliness of the staff here is completely unmatched. Everyone here is very courteous and professional and makes you feel incredibly comfortable. I will never go anywhere else, the atmosphere is just THAT good, truly!"
"This is one of the best run doctor's offices I've had the pleasure of visiting. The staff is friendly + knowledgeable, and it's clear that they have processes they're following, which creates an environment where you know exactly what to expect and how much it's going to cost. On top of that, Dr. Weinstock is top notch and has an excellent bedside manner. I've been struggling with GI symptoms and a lot of other crazy symptoms for a few years, and he listened carefully to everything I shared (in addition to collecting much of the information up front in a thorough intake questionnaire) and help me determine that I have Mast Cell Activation Syndrome (MCAS). After doing a lot of research about MCAS, it's clear to me that I'm working with one of the best doctor's in the country and am insanely lucky that I found him this early into my journey. His protocol has helped me get a significant amount of symptom relief, and I'm optimistic that by digging into the root causes with another local STL doctor (Dr. Christian Wessling), I'll be on the road to healing. One other thing I love about this office is that you can get support between appointments using their patient portal, and their responses are thoughtful and prompt. All doctor's offices should take a lesson from this one on how to run their operations while providing excellent patient support! 👏👏👏"
"Dr. Weinstock was very friendly and professional! Phenomenal doctor! After my procedure, he explained his findings in terms that were easy to understand and answered all my questions! The nurses and staff at MoBap were also phenomenal! Couldn’t have asked for better care! Highly recommend Dr. Weinstock and Missouri Baptist Hospital!"
"Dr. Singh and her whole staff could not have been more nice and professional. I will definitely be going back to their facility in five years. What an awesome group!"
"Dr. Banerjee, the anesthesiologist, the nurses, and the check in staff were all very warm and knowledgeable and do everything they can to made you feel at ease. They have an efficient system down and there was no wait time getting me started on my procedure. I definitively recommend them."
"The supporting personnel are all very efficient and professional. They go out of their way to make you comfortable. Dr. Thyssen is awesome. He is so positive and explains the test results very clearly. Even though it is years between tests, he never forgets you. He, too, is so professional."
"The entire staff has an efficient process with a warm and inviting feel. They let you know exactly what is going to happen and are so friendly. They are compassionate, efficient, and professional."
"My upper and lower endoscopy went smoothly. Dr. Banerjee and his team are phenomenal. They have the grace to usher patients through what could be an embarrassing position (literally), and make everyone feel comfortable (and even share a great sense of humor). I’ve been a patient at this practice for years and couldn’t be happier, both with Dr. Banerjee and my previous doctor (retired). Thanks to the whole team. You guys are amazing!"
"Dr Root was very friendly and explanatory of the process and procedure. Ensure me that everything was going to be all right , made me feel very comfortable. Kudos to the whole staff, they were PHENOMENAL!!!"
"I’ve seen Dr. Singh off & on for over six years after my daughter-in-law recommended her. Im so glad she did!! She explains everything in lay persons terms. She found the root of a problem I had that mimicked heart problems. Other doctors left me to believe it was in my head. Highly recommend Dr. Singh!"
"Dr Root was extremely pleasant and had an awesome bedside manner. He was totally tuned into what I was saying and really made me feel secure with being under his care. The older doctors are passing on the torch to the newer young doctors. Congratulations Dr Root. Glad to be a patient under your care"

"My father in law sees him, i am a cardiologist, and this man may as well be god! He made a diagnosis on a family member that no other doctor would likely make. He is amazing and would see him myself!!"
"Dr Thyssen is a compassionate and friendly physician. He took the time to explain everything to my mom and myself, and made us feel comfortable with the upcoming procedure. The employees at SIG were all easy to deal with, understanding and made my mom's experience comfortable and stress free. SIG has appointments and procedures all in one building which makes for ease of patient care. There's no running the gauntlet of hospital corridors, registration and bouncing from one area to another. I would highly recommend Dr Thyssen and his staff."
"Dr. Root, the techs, nurse anesthetists—everyone was so amazing! Really made me feel at ease and cared for throughout the whole experience. It was my first colonoscopy and I couldn’t have asked for a better team."
"I liked Dr. Banerjee. He seemed very professional, concerned about the procedure he was about to perform and took every opportunity to keep me informed. I'm glad I went to the Advanced Endoscopy Center. In fact everyone in that entire experience made me feel as though I would be taken care of in a very professional manner."
"Dr. Root and the entire staff were very friendly and professional. I was extremely nervous about my procedure and they made me feel as comfortable as possible. I will definitely continue to follow up with Dr. Root and will highly recommend family and friends use him for their GI medical needs."
"Dr. Erik Thyssen has a wonderful bedside manner. He made me feel comfortable prior to and after a very intimate procedure. The entire staff that worked with me made this go very smoothly and my anxiety level was very low. Thank you!"
