For all consultations Dr Williams was on time. He has a friendly calm manner which would set anyone at ease straight away. I suffer from panic attacks in medical settings and he did his best to reassure me and ensure I understood what was being explained and what procedures / tests were required and why. The team that supports Dr Williams was also a big reassurance from the admin staff through to his support medical staff. This made the entire process a lot less daunting.

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.

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.

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.
