I had a series of visits for tests and then heart surgery. On every occasion the entire team were friendly and professional. They went out of their way to make the experience as worry free as possible, with mr Whitaker taking time to explain what was happening at every stage. In short, a perfect example of why our health system is unique and envied world over.

Dr Whitaker carried out the fitting of my pacemaker and the follow up consultation. He throughout the whole time has acted in a friendly but very professional manner and is clearly very competent. The operation went well and throughout the whole process he has explained all I need to know giving me great confidence. For the follow up I had two appoints being initially for some tests and calibration of my pacemaker the for a consultation with Dr Whitaker. I arrived slightly early for the tests and was seen right on time which to is a nice surprise for a hospital and since all that was over with quite quickly I assumed I would have an hour wait since the appointment for Dr Whitaker was not until then but in fact he saw me straight away which meant I had no wasted time and could get home before the rush hour which was much appreciated. I can honestly say I would recommend Dr Whitaker.

Dr. John Whitaker took the time to really listen to my symptoms and concerns. I was very nervous about what I had been experiencing, but he approached the appointment with a calm and attentive manner that immediately helped put me at ease. He listened carefully, asked thoughtful questions, and made me feel genuinely heard rather than rushed through the consultation. His bedside manner was excellent, and I left the appointment feeling reassured and supported. I’m very grateful for the care and attention he showed.

I first met Dr. John Whitaker when he was a Senior House Officer and encouraged him to pursue a career in electrophysiology. Since then, he has become an expert operator in the field of ventricular tachycardia (VT) ablation, and we now perform our most complex VT ablations together. These cases often involve prolonged procedures with both endocardial and epicardial approaches, requiring advanced techniques such as phrenic nerve deflection and venous alcohol ablation. I have complete trust in his skill, judgment, and dedication to achieving the best possible outcomes for patients.
