I found Dr. Kadam to be very personable. He answered the questions I brought with me and explained the next course of action to be taken. I still have difficulty with all the medical terminology and some test results but I am learning what they mean in terms of my health. I would recommend Dr. Kadam and his colleagues from Long Island Gastro.

When I first saw the Dr he listened to ally concerns and was quickly to figure out my issue. Since I have been treating with Dr. Sideredis , I have been feeling so much better. Only wish I would have found him sooner!

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.
