Dr Barnes was very thorough and clear on what was important and what wasn't. He explained his thinking and answered all my questions at a rate that I could make notes and gave confidence. He was thoughtful and had good empathy. He could not have been more helpful or patient. Dr Barnes was strongly recommended to me by my cardiologist, and I would completely endorse this.

Over the last 5 years I have had very positive experiences with Dr Barnes. From the outset, Dr Barnes was personable, caring and reassuring, taking the time to listen carefully and explain everything clearly. I felt genuinely heard and supported throughout my care. Dr Barnes has a warm and approachable manner, while also being professional and thorough. I really appreciated the kindness, patience and attention shown during my appointments.

I felt that the doctor was extremely thorough in assessing my current symptoms as well as my other long term health conditions.. Dr Barnes carried out a very detailed examination and discussed the management plan with me. I have seen many doctors in various places for a number of health concerns, but this experience was far the most satisfactory.

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.
