It was lovely meeting Dr Williams — he was polite, professional, and put me at ease straight away. Thank you for your time today. I know coming in for a watch reading felt a bit over the top, but he was incredibly reassuring, and I’m genuinely grateful for all the tests being done. If everything comes back clear, it will give me real peace of mind.
Dr Williams was very thorough and I felt extremely confident that my concerns were being listened to. A very clear and thorough course of treatment was scheduled Thank you…!!
I had been unwell with BP issues(probably worse with the hot weather) and had my medication changed by my medical practice. This made things much worse. I went to see Dr Williams very promptly and he thoroughly examined my condition and treatment. He was very professional and reassuring.
Mr Williams was very professional giving me good advice and information. I felt very at ease with him.
Good care, good facilities and reassuring medical advice and treatment.
Dr Williams was excellent. He was very calm and reassuring, listened to my concerns and made me feel at ease. The procedure went very smoothly with no pain or problems and was much less stressful than when I had the same procedure four years ago. I felt very well looked after throughout.
Seeing a cardiologist can be stressful, but Dr. Williams made the entire process reassuring and seamless. He took the time to explain everything clearly, answered all my questions, and made me feel completely at ease about my heart health.
Dr Williams put me at ease straight away and was a delight to speak to about my issues. I was quite nervous initially but his calm, confident and friendly manner was very welcome.
I had a great experience with Dr Williams, would recommend & will enage with him again.
Dr Williams calm manner puts you at ease right away. He listened to my concerns and explained what the next steps would be. I have every faith in Dr Williams and would not hesitate to recommend him.
