Dr. Sideridis has been my doctor for years now and I will never go to anyone else. He is one of the only doctors I’ve ever met that truly listens and takes time to understand a patient’s concerns. I suffered from sucrose intolerance my entire life without knowing and he diagnosed me when hundreds (no exaggeration) of previously seen doctors ever could find the problem. He looks at the whole system to determine proper treatment and he actually cares. He has extensive knowledge and experience. He is warm and trustworthy. Why see another gastroenterologist? He’s the best out there. Thank you Dr. Sideridis for everything.

It was my first colonoscopy or as Dr. Sideridis said “my maiden voyage.” He has a great bed side manor and really put me at ease. His nurse and anesthesiologist were a great part of the team too. I recommend this practice!

I met Dr. Sideridis in the ICU at Plainview Hospital in 2016. I was at that time in organ failure due to vomiting and diarrhea. He diagnosed me and I have been seeing him ever since. He is a diligent doctor who explains everything in detail. I would recommend him to everyone.

I have been going to Dr. Kadam since 2013 when he found my cancer. I trust him completely and have recommended him to all my friends. My daughters have also gone to Dr. Kadam for their colonoscopies.
His caring and concern for his patients is what makes the difference.
I RECOMMEND HIM 100%. Cathy Burns

I had a routine colonoscopy at this office. Dr. Sideridis is professional, answers all questions and has a wonderful rapport with his patients. As an RN myself, I am never thrilled with being anesthetized in an office. The anesthesiologist, Dr Malone took a thorough history and asked all the right questions. I felt confident in her abilities. Bring a jacket office is cold.
