Very positive initial consultation. It is still early days, with tests and results to follow, but so far I am really pleased. Dr Barnes listened, explained things clearly, and took the time to understand the wider history and symptoms. I left feeling reassured and with a plan for the next steps.

Dr Barnes put one at ease and gave one his full attention, not looking at a computer screen like some doctors. He took a detailed case history and a very thorough physical examination. He was very reassuring, explained the blood tests to me.

I enjoyed a very pleasant and thorough, although a little inconclusive, consultation with Dr. Barnes. However, this was partially due to the difficulty in obtaining up to date information from my local surgery. This will now be rectified by further tests at the Nuffield Hospital in Tunbridge Wells. Dr Barnes explained the situation with the condition I have in a very professional and caring way and gave me adequate time to ask any further questions about the possible processes involved in achieving a probable cure.

Thank you for the positive feedback. I hope that the further tests will help with a definitive diagnosis so that I can recommend a specific management plan.

I have worked with Dennis Barnes for almost 25 years. He is a very experienced, wise and extremely capable consultant colleague. What he doesn't know about endocrinology is not worth knowing! I have no hesitation in asking him to see my patients with metabolic or hormone problems.
