“Following a visit to my GP I was referred to Professor Chan. I very quickly got an appointment with Professor Chan and after taking a few minutes to explain to him what the problem was he very quickly gave me an explanation and diagnosis. It was so nice for someone to eventually know exactly what I was talking about. Professor Chan prescribed some medication which worked almost straight away and I have been nearly symptom free ever since. Fantastic result!!” K.N.

It was obvious to me that he is an experienced doctor, in his field. He is an honest man who explained what he had found out, in a straight forward and easy to understand, way. I have now seen him again. this time in November/December 2019 and in my opinion he has not changed at all. My family were also, very impressed with him and his attitude.” D.M.
