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!

The staff are all very accommodating and pleasant. Dr. Sideridis is a kind and caring doctor with a wonderful bedside manner.
