"My GI doc for 30 years recently retired and I was hearing horror stories about finding a new GI. Luckily my GP recommended Dr Merel and I couldn't be happier. Her office, the staff and the facility where she does colonoscopies not to mention Dr Merel herself were all top notch. Highly recommend!"
"Doctor was good in terms of direct suggestions to deal with my issue. The only disappointment about this first time visit is how rushed the doctor was. I was told by the referring person who is a patient of the doctor, that she is calm and takes time to listen. This was not my experience. Perhaps it was one of those extremely busy days. Nonetheless I will continue to keep her as my GI doctor."
"This was such an easy experience- I was in and out in an about an hour- no pain or discomfort whatsoever. Everyone was professional and friendly. A seamless experience all around."
"Dr. Merely seems awesome, knowledgeable and thorough. Her support staff need coaching. The made me wait 45 minutes for the scheduler then told me and a waiting room full of people waiting to go, the scheduler will call. My time is valuable too, if he was that far behind tell me we are done right away and expect a call. Not well managed."
"The visit was fine with the Doctor! I did feel at the end that I was being rushed a little bit but most of the problems were addressed and hopefully I will get some positive results !!!"

"I have been with this practice for over 25 years. I started with Dr. Levitan. When he retired I switched to Dr. Merel and have been very happy with her care."
"Dr. Merel is kind, understanding, and open to feedback around my care. Only note is it can occasionally be hard to get in touch with her. But that is more because of the front office and not necessarily her responsibility to manage."
"The pre-prep to the drug store was wrong and I had to call to rectify. Had to make 2 trips to Walgreens. Also they gave me 5 places to get a PCR Covid test, which Golf Surgical Center does not take. They only accept the test from Evanston or Libertyville. Dr Merle was great but their help should get their direction and prescription right."
"Dr. Merel and her facility and staff were exemplary! Everyone did their job without fault. From the front desk, nursing, anesthesia to Dr.Merel herself, I was in expert hands and received the finest care. I would highly recommend this facility where they do their job with precision and confidence."

"My internist originally referred me to Dr. Merel several years ago for a routine colonoscopy and endoscopy. She has since treated me for a few gastric problems. She is an excellent diagnostician and I wouldn't be here today had I not gone to see her. She is very caring and goes above and beyond in taking care of her patients. I wouldn't go to anyone else and I would strongly recommend her if youou are looking for an excellent gastroenterologist."

"Dr. Nina Merel is wonderful, her team is as well, they are professional, efficient and very nice to work with. Each step in the process is fully explained, questions asked were addressed right away, the timeline was adhered too also. Each person involved explained their role as it pertained to the procedure. This was the second time I utilized Dr. Merel and Glen Endoscopy we're the only professionals I considered when it was time for a second visit. I would highly recommend these professionals to any one and in fact have made several referrals to friends. Thank you."
"Dr. Merel has a warm and friendly bedside manner. She makes you fell comfortable in “uncomfortable “ Circumstances.

I have no intentions of finding a new doctor out here! I have great confidence in her."
"I have been very pleased with Dr. Nina Merel and her staff. She was recommended to me by my primary physician many years back. I have not been disappointed with her bedside manner; she takes the time to speak with me before and after the procedure with calmness and professionalism. She explains everything thoroughly with graphics in addition to a game plan for improvement. I moved further away further from her office (45 minutes w/good traffic); However, I kept her as specialty physician because the service I receive is worth it."
