Collecting a lot of information about patients and their siblings, I think doctor is collecting data and sell it later. Also taking picture of patients. This is the doctor in hesitate who takes picture of patients. I won't recommend.

Dr. Sideridis when I meet him a few days before Christmas years ago was like the Angel of Mercy. He listens to me, he hears my problems and takes care of all my medical issues. Plus, he stays in the loop with all my other Doctors to make sure they’re doing the correct things with not only my Crohns but the 3 other autoimmune diseases I have. I can’t thank him enough for being my Best Doctor out of the 11 I have. I can say he’s the most caring man in the field of Medicine.

I was totally dehydrated and came to see the doctor,rather than sending me to emergency room he gave me 4 liters oF saline in his office and stayed after the it closed so I could finish the treatment. He and his staff were terrific!

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.
