Prior to my procedure , I had the worlds sweetest nurse. She made me feel so comfortable ! She was friendly and made feel assured that I had nothing to worry about ! I wish I could remember her name (pink scrubs). A friendly face always helps.

Dr Kadam is fantastic but shocked to see bills in excess of $6000 for lab work that is outside of the network. They should mention that all labs and anesthesiologist are outside network. It’s painful trying to rectify this. Still not rectified. Anyone going to LI Gastro needs to verify this. While Dr. Kadam is in network, the rest is out of network. Be prepared for a hefty bill. The office just ignores and says to address it with the out of network providers. I would happily give 5 stars but can’t due to these bills.

Dr Kostas Sideridis is the best doctor in the world. He addressed my issue explained what steps he would take to investigate my digestive issues. I went for testing the following morning and he called me with the result ASAP!Cant get better service than that. He answered all my questions and is very knowledgeable. Not an alarmist! I would recommend Dr S to everyone I know and to all I don’t know!

l am a nervous patient. Dr. Sideridis is a kind and caring person who made me feel at ease at our very first meeting. When I returned for my procedure he reassured me and calmed me. The staff are all very accommodating and pleasant. Dr. Sideridis is a kind and caring doctor with a wonderful bedside manner.
