Very knowledgeable and friendly consultant. Easy to talk to and explain symptoms to .


I have recently attended St Peters Hospital for a coronary angiogram and had 3 stents put in to two of my arteries. The care provided by Dr Mark Williams and his team was outstanding. Leading up to my new stents and after the procedure I felt very much cared for by providing me information and support for what was going to happen and about the recovery. I felt very much reassured by Dr Williams experience, his understanding of my situation and the time he gave me. Thank you for your great care, it is much appreciated by my wife and I.


At a very worrying time, Dr WIlliams was a very calming influence and explained every procedure to me in great detail. He was extremely thorough and left no stone unturned. Through the procedure of the Angiogram, he made sure that every member of staff in theatre introduced themselves and again, put in at ease and gave me complete confidence at a time that could have been very tense. The aftercare and follow up was equally as pleasing, at no point throughout my experience did I have to call to chase for anything. When Dr Williams said he would call he did, which reduced stress levels. Thankfully, I have been given the all clear, but from the start I was made to feel very confident in Dr Williams and his teams ability, everything was done in a quick and timely manner to reduce stress levels, I honestly cannot find one fault. I do not often feel compelled to leave a review, but here we are ! Thank you for everything, it really has been appreciated. Gary Sandhurst




Dr Williams from a patient perspective is very good. His manner is friendly and professional. My appointment was on time and didn't feel rushed. He answered all of my questions and some I hadn't thought of. He kept me informed at each stage of the angiography and having identified I needed an angioplasty and more stents he carried out the procedure with a good bedside mannor. The after care I received was again very good.


My name is David Healy, I am the son of Mr Martin Healy, my father is 83 yrs old He has suffered many medical issuses over the last 10 yrs from prostate cancer, major back surgery, hip replacements, a stroke , 2 heart attacks to double heart by-pass surgery - and there is more! But as he says - im not ready to go, and as hard as they try to put me in the ground the more i will fight! My dad never moans, one of the reasons for this I believe is the excellent doctors, nurses and the people in the background that have always helped him. One Doctor in particular, Dr mark Williams I feel deserves a special mention, he is my fathers heart doctor (his words). from the moment I received word that my father had 2 heart attacks, Dr Williams has been so proactive in helping my father. He has a very caring manner, he is always positive and more importantly he makes things happen, The other thing we like is, there are many ways to break often difficult news to a 83 yr old, every time he has been totally honest but has been also been to get across to my dad, lets be positive, you can do this. My dad and my family could not be happier with the way things have been carried out. From a personal point of view, I think I need to mention something else, Like every son I love and care about my Dad, there have so many occasions when I have been worried about him, especially when he recently suffered a stroke whilst abroad, I did not know what to do or where to get information to pass onto the other hospital abroad. I emailed Dr Williams at 11pm at night with my worries and concerns and asked would it be possible for him to call me the following day, he personally text me at 11.20pm and asked could he call me now - totally incredible, he organised everything for me and he personally spoke to the hospital abroad to go through my fathers past history. Dr Williams for me is like a family member - he always cares about my dad, Thank you so much! I could say so many good things about him!

Dr Williams is a fantastic cardiologist and has been looking after patients I referred to him over last few years. Patients like him and understand the management plan given by him as many of them are on 5-6 complex medications for the heart. He is available to advice me if urgently on the phone if required and is able to see the patient quickly if any concerns.
