Dr Williams is calm, thorough and explains issues clearly. He pays close attention to detail and takes prompt action when necessary rather than delaying treatment. His PA - Ava, is excellent at follow-up and communication. Both are professional, patient and responsive, consistently addressing requests quickly and effectively.
I arrived in the A&E department of St Peter’s hospital and within an hour and a half I was being wheeled up to the cath lab for an emergency Angiogram, as I was having a heart attack. Dr William’s was the person on shift that night and he performed a successful angiogram, opening an artery and inserting a stent…effectively saving my life, as it was the main artery that was blocked. 3 days later I went for another Angiogram where a branch off of the main artery was also opened up (with balloons). During the whole process, Dr William’s was professional, affable and informative, making me feel at ease in a very scary situation. It has been two weeks since my heart attack and I am on the road to recovery, thanks to Dr William’s and the medical team. I would not hesitate in recommending Dr William’s to anybody with any issues or cardiac concerns. I have seen Dr William’s within the NHS and privately.
