My husband recently passed away from stomach cancer. Dr. Chris made the diagnosis 2 years ago. He broke the news to us in a soft and caring way. He guided us through surgery and chemo. My husband respected him tremendously. After my husband died he called me and spent an hour on the phone with me. The words he spoke were so comforting and allowed my to see life differently, he uplifted me. There is no second option when it comes to selecting a doctor in his field. God Bless you and thank you.

Dr. Demetriou is an intelligent, professional, and caring doctor. He has been my doctor for many years. I no longer live in Nassau county but will always have Dr. Demetriou as my gastroenterologist. He also has a very competent, caring staff which is a reflection of his personality.

Special Person I got a great recommendation from my partner to see Dr. D. I wanted him to see my 16 year old daughter. At first the office told me he only sees 18 and older, but after begging they asked him and he said yes. He made her feel so comfortable and spent time listening to her. He told us a clear plan of what testing needs to get done to better understand her bloating and diarrhea. She ended up having fructose and sorbitol intolerance and after dietary changes she is feeling great

I know DR. CHRIS for over 2 years. I owe him so much, he first convinced me to have a colonoscopy where he found colon cancer. He spoke to me with so much comfort and care when giving my husband and I the news. He personally contacted the radiologist, oncologists and surgeon where I felt all the doctors were working together. He controlled the whole situation for me and i never felt alone. The best doctor I have ever seen. His office also looks like a palace.
