“I had gone to Dr J Erber for years for colonscopies. They were done in his office, which is in my neighborhood( a 3 minute walk). Now its time for another colonscopy and he wants to schedule me at his groups "new endscopcopy center" on the UPPER EAST SIDE. This would require a 10 minute walk, then 1 hour subway ride. Absurd to tell a patient to go on a 1 hr train ride after a colonoscopy prep!! I asked about a Brooklyn location, said its reserved for patients that need a hospital based procedure. Then, he became annoyed when I asked for this option... that I cannot travel to Manhattan... then told me to go to another gastroenterologist!”
“Nice office staff and very thorough and kind Doctor. Personable and professional.”
“The absolute BEST!!!”
“Dr. Miller was professional, listened to me and didn’t rush me or downplay my concerns. I feel safe in his care, and he answered my message on the portal very quickly. I am so happy I found him.”
“Dr. Adler is an absolute gem! From the moment he walked into the room, his calm and reassuring presence immediately put me at ease. His bedside manner is truly exceptional, and he took the time to make me feel comfortable throughout the entire experience. I was extremely anxious about the procedure beforehand, but it ended up being incredibly smooth and virtually stress-free. It was, without a doubt, the best experience I’ve ever had with a medical procedure. I can’t recommend Dr. Adler highly enough!”

“I recommend Dr Kavaler and his team at NY Gastroenterology. The staff are welcoming and seem very well-organized. They make you feel that you're in competent hands, because you are. Very smooth admittance and prep for procedure. Dr Kavaler takes time with you, and is happy to explain everything if you have questions. I had a minor issue following the procedure, left him a message on the patient portal, and he called me on the phone right away to hear my concerns and offer help. He makes you feel well cared-for. This was my third colonoscopy done by him, and I would definitely recommend him.”
“Professional, courteous, and calming. From the check-in until my walk out. Knocked it lit of the park. Dr. Wu anesthesia, Dr. Pacheco Super Stars”
“Excellent physician”
“Dr Naymagon gave me complete confidence in his abilities and knowledge. His very timely responses to my inquiries thru the portal was greatly appreciated. At no point did I feel like I was bothering him. He has the perfect balance of being highly professional with a warm bedside manner. His quiet confidence is greatly reassuring.”
“For an unpleasant procedure - Dr. Naymagon and his team were beyond pleasant and absolutely spectacular medical professionals from minute one. Cannot recommend him highly enough!”
“Again a great place to go for highly competent medicine. And a well run organization. I can’t find anything to fault.”
“Dr. Miller was attentive and listened to all of my concerns. He is proactive and thorough. In addition, his office well organized and easy to navigate and his support staff is highly professional and excellent and following up.”
“Excellent; attentive listener; fine doctor .”
