Was great.

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

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.

I have an old patient of this clinic under Dr. Abraham and have always been satisfied and very happy with my visit experience.

The clinic was clean and modern, with friendly approachable staff. I highly recommend the London Heart Centre!

Great experience, felt very well looked after. Great team!

I had a lot of pain and trouble for a long time now with my kidneys. These guys were the first clinic to finally come to an actual diagnosis and recommended treatment that actually works and I am so thankful to them for this. It makes me so happy that I’m finally getting better and after so long of running around everywhere else the team at London ultrasound were able to help me. I now go back for some yearly check up’s.

The facilities and the organisation of the day were excellent
