Was great.

I am happy for the clinic experience.

Friendly & knowledgeable and Professor Sam Mohiddin explained everything to me expertly. Thank you.

Very calm and friendly environment.

Excellent experience, would highly recommend

I can’t recommend Dr. Teresa Castiello highly enough. From my first appointment, she put me at ease with her warmth and professionalism. She’s not just an expert in her field—she genuinely cares about her patients. She takes the time to explain things clearly, making sure you understand your condition and options without ever feeling rushed. Dealing with heart issues is daunting, but with Dr. Castiello, I always felt in safe hands. Her attention to detail and thoughtful approach made a real difference, not just for me but for my family too. She listens, she reassures, and most importantly, she makes you feel looked after. What sets her apart is her dedication—not just to cardiology, but to people. She treats her patients with kindness and respect, always making sure they feel supported. It’s rare to find someone so skilled yet so down-to-earth, and I feel incredibly lucky to have been under her care. If you’re looking for a cardiologist who is not only brilliant at what she does but also compassionate and approachable, Dr. Castiello is the one.

Very friendly and helpful staff. The whole experience is very smooth.

Clean, efficient

St John & St Elizabeth is a wonderful place for treatment, other than the imaging department. The Cardiac Suite team is exceptional.

It was a pleasure receiving care at Nuffield Health, the clinic is calm, modern and spacious and functions very well plus all the staff are very friendly and professional. I underwent a coronary CT angiogram which on the whole went smoothly. Perhaps some minor suggestions concerning the fact that due to a previous mastectomy my veins on (useable) only one arm required a bit more skill regarding inserting a cannula & taking blood. And although I researched the procedure beforehand to explain it in detail in person then and there would have been good. The doctor who dealt with lowering my heart rate did not introduce himself or explain his role. Yet overall it was a very good experience.
