Long Island Gastroenterology Specialists, Wantagh NY

Dr marshak is literally one of the most personable, kind and caring doctors I’ve ever had in my life.

Dr Marshak is a excellent Doctor. He spends time needed to address all your concerns. Staff in this office are all very polite and attentive.

When my pain and discomfort needed medicaI attention, I called asking for an appointment with Dr. Marshak and was able to see him the same day. The doctor and his staff were wonderful.

My whole experience was wonderful, starting with John. He was so helpful and friendly! Dr. Carly Barth was absolutely incredible! She took the time and listened to everything I had to say and did not rush me. After the appointment I immediately went to the front desk where they scheduled my procedure, the COVID test I have to take before it and the follow up appointment. So efficient! When leaving, John rushed outside to guide me out of the parking lot because I was making the left on Wantagh Avenue. Really? ! What doctor’s office does that? !
I am so happy and will recommend Dr. C. Barth and the entire practice to anyone who needs a gastro.

I received courteous professional service by the front desk, medical technician and Dr C. Barth. I was impressed by the level of listening and thoughtful care. Looking forward to adding Dr C. Barth a member of my healthcare team.

Dr. Rush and his staff are wonderful. From the person who made my appointment, the adorable greeter in the parking lot, and the rest of the staff I thank you. Dr Rush listens and no pun intended does not rush you. Professional, knowledgeable, and caring office.

From the moment I pulled into the parking lot I was greeted by John who confirmed my appointment and checked my vitals. He then escorted me into the office where the rest of the staff took over. As a new patient I can honestly say my visit with Dr Marshak was efficient and thorough

Was met in the parking lot by very friendly and competent gentleman who escorted me into office and took my temp. The office girls are excellent and overall it was a very successful experience. The PA Corri Wolf was excellent and I scheduled my colonoscopy that very day.

The staff's friendly professional and helpful. Dr Rush is very informative and answers all questions

Only my second time seeing Dr Carly Barth, but made me feel very comfortable and addressed all my issues. Very professional, yet very down to earth.

The Dr. I go to is Dr. Rush, excellent, thorough, highly recommend him. Office staff is pleasant and efficient. The man that greets you at the door his name is John, so very nice and pleasant!

Dr. Razzano is an absolute professional and listened to my issues. I would highly recommend him to anyone experiencing GI problems.

Friendly greeter as soon as you pull in the parking lot. Dr. Anthony Razzano answered all my questions and was very helpful.

I was super impressed with William, the MA, and Dr Marshak was amazing! Thank you for getting me in today!
