    Good experience of Dr Kallis. Was seen on time and treated politely and friendly manner. He took time to explain the Fibroscan capability (and limitations) to me and the measurements were made swiftly and accurately. A report and cover letter followed later on.

    Patient seen for:
    I found everything associated with Dr Kallis to be exemplary. His explanations were clear and delivered with great EQ. According to my Executive Assistant (who bore the burden of fitting the procedure in, as a matter of urgency, amongst a crowded diary), Dr Kallis' attitude towards his patients was repeated by his PA who - rarely amongst medical administrators - was helpful and constructive in the extreme. I hope that none of my friends and associates experience the biliary malfunctions which placed me in Dr Kallis' hands - but if they do, I will have no hesitation in recommending him (and his office) with enthusiasm.
