"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."

"Dr. Nina Merel is one of the best doctors who has treated me; and that's saying a lot since I've had multiple hospitalizations and 8 major surgeries. In fall 2020, Dr. Merel accommodated me during Covid within 24 hours. I had made a mistake in prepping for a colonoscopy and Dr. Merel reset the appointment for the next day & got me another Covid test within that same 24 hr. period. Her dedication to her patients is remarkable. Dr. Merel is considerate, has a wonderful bedside manner and, from my experience, obviously cares about her patients."

"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."

"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 and her group saw me on an emergency basis in March of 2016. With red tape from my blue cross blue shield health insurance I was getting overwhelmed from all ends. Dr merel and her staff navigated the health insurance issues like champions and quickly gave me world class health care. I can't thank the group enough !
