Gastrointestinal Specialists of Long Island

Very easy to get an appointment. Then I was contacted just a few days later and they had a cancellation and I was able to fill that spot! Dr. Marwil for very thorough and covered everything. The staff works well together and they are right on top of everything. I could not be any happier with my visit.

Dr. Marwil is one of my favorite doctors which is hard to find. He is thorough and has a very good bedside manner.

His expertise is extraordinary! Sincere and heartfelt consideration & understanding just comes easy to him! No matter how much you're hurtin', he makes the pain go away with his smile! I consider him 'one of the best'!!!! 'Been with him for more than a decade; and, will stay for another! Thank you & warm regards, From Richard

When I went in for my appointment I was so very nervous and the way Dr. Novak took his time and explained everything to me I felt so much better when I left. The girls in the office were very nice, also.

Dr Marwil is a great doc. He takes plenty of time with you, never rushes you out and addresses all of your medical concerns. I’m lucky to have him as my Dr.

I was very impressed with Dr. Marvil. He was very professional. I was not rushed at all. Very pleasant experience. His staff was also very nice and welcoming.

Dr. Novack educated me on my Endoscopy very Well. I appreciated his manner and Professionalism!
