"She's the best GI MD I've ever seen. She's smart and extremely informative. She's finally figured out what's been wrong after years of searching with other doctors. She's not only thorough but very gentle. An important attribute when considering these types of procedures. I have complete trust and confidence in her."

"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 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."

"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."

"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. Merel has a warm and friendly bedside manner. She makes you fell comfortable in “uncomfortable “ Circumstances. She takes the time to make sure you understand everything and always takes the time to answer your questions. I’ve been going to Dr.. Merel for a few years and have since moved quite a distance away. I have no intentions of finding a new doctor out here! I have great confidence in her."

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.
