Dr Barnes has been incredibly helpful, from my initial DKA episode right through to my diagnosis and plans going forward. He had clearly read and studied my medical history beforehand, spent a long time explaining everything thoroughly and I felt all my questions were answered. A truly kind doctor who goes well above and beyond - I would highly recommend Dr Barnes to any patient.

I have found Dr Barnes to be an excellent physcian. His knowledge and experience of the thyroid and replacement medication, has benefited me enormously. He listened fully to the problems I was having. I trialled a combination therapy of T4 and T3, which has improved my energy levels and decreased my blood pressure. I feel that Dr Barnes really cares about his patient. An extrememly kind man who is very thorough with his diagnosis and he is unstinting in his care.

Dr Barnes was on time. He was very clear about the process to be followed and ensured that he had obtained all relevant records an information. He tried to use the time and costs wisely by leveraging other parallel appointments. Most importantly, i found him to be professional, courteous and through.

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.
