Success Stories

I have been with Dr. Neeraj Kaushik many years. He is absolutely outstanding physician / specialist who went above and beyond to find the cause of my disease and helped me fully resolve an ongoing issue. Dr. Kaushik is very professional, knowledgeable and kind. Any questions, troubles, issues - he always knows the answers for me and takes time to explain everything in simple words that non-medical person can understand. He and his respectful staff ensure that you receive the best treatment possible. I have nothing but trust in and respect for him and his team and would not consider using anyone else. Many thanks, Dr. Kaushik!

I went in for a colonoscopy and endoscopy. I got nice treatment from the staff. They made me feel very comfortable and were very professional. The doctor also spoke to me to make me feel at ease. Both procedures went smoothly. I highly recommend Dr. Kaushik.

Wife of patient Jack B

Having a series of highly complicated and “ mysterious “ Digestive Issues I consider myself extremely blessed to at last having found Dr Kaushik! Yesterday I had to have a procedure which I feared to the point of nausea! But , this Physician calmed me , his demeanor was so reassuring and caring with his impeccable bedside manner ! What a Gem ! His team at North Shore Hospital was equally nice and comforting, I highly recommend this Physician to everyone, especially to those who like me have “ unresolved “ Gastric problems, trust me he’s the best !

Best Gastroenterologist on Long Island

Dr Kaushik is really a very patient, knowledgeable, hands on , caring Doctor. When I first came to him, he didn't want to know only current symptoms and took time to listen to my complete history in detail and was able to predict and diagnose my Celiac right away. I am forever thankful to him and his staff for their help and care. I was very regular with other GI Dr but they could not provide relief when I needed it which led to my health deteriorating. He is very accommodating and an awesome Dr.

Life savior

All doctors should be as good as Dr Kaushik. After an endoscopy/colonoscopy I went home and I saw something when I went to the bathroom. I called his answering service @ 7pm and he called me back in less than 10 minutes. All the gals and 1 guy (shout out to Alex) are young and knowledgeable. Your staff can either ruin or enhance your practice and they make his practice outstanding.

Paul D.

Dr. Kaushik is a life saver. I was misdiagnosed by previous doctor as having a benign pancreatic condition. Dr. Kaushik determined that I have stage 2 pancreatic cancer. He gave me a chance to fight this condition early. I am thankful for him.

Paul S.

Dr. Kaushik is amazing! He’s so easy to talk to, very warm and understanding. I trust him fully, he’s extremely smart & extremely professional. I’m very grateful for his help! Gabrielle Hoffman.

Gabrielle H.

Dr. Kaushik diagnosed, in my first visit with him, a condition that had me seeing multiple doctors for WEEKS trying to diagnose. Once it was confirmed he knew the exact course of treatment and has been my GI since then with diligent and timely follow up. His office staff run a very well maintained practice with excellent response time and the people are friendly and knowledgeable. Highly recommend.
