Very clear and helpful explanations given.

thank you
Dr Felekos was extremely well mannered and very clear when explaining my mums condition and instructions on the next step of her treatment. What I liked very much is that he spoke to both of us not just my mum. That means a lot as I care for my mum and she does struggle to retain information especially when it is a lot. Eye contact was fantastic. Great care was taken when Dr Felekos examined my mum. We both walked away from the appointment understanding everything Dr Felekos explained to us. Overall I would definitely say he is one of best physicians we have seen. Thank you so much.

thank you for your feedback
It was very helpful and informative given lots of time to talk and felt really listened too … He is a wonderful man

I think it is important to allow my patients to voice their concerns and give them the information they need - glad you found this helpful
I very useful visit. Dr Felekos was friendly, concerned and caring. He immediately changed 2 of my tablets and prescribed a third to try to help me, as well as arranging a scan and an angiogram. I felt very confident in his knowledge and was very grateful to him for helping me do much.

happy to help
Experience was good doctors explained it could be hereditary so need my children to be tested . Good that he sends me for scan so I know how bad it is and if I am having surgery. He asks if I have any questions but I need to write them down before so I am prepared.

Thanks for your review
2 years ago I had a heart attack at home. I was rushed to BHI where Dr Felekos and his team performed an emergency Stent operation. This was a Sunday evening. Within 48 hours I was back home with no complications. I can't thank him and his team enough. The discharge from his care was quite emotional for me but Dr Felekos was excellent.

It is always fulfilling to see that an intervention makes a great impact on people’s lives
Very welcoming and explained everything clearly. Allowed me to ask questions. Felt reassured and happy when I left.

Glad you found the consultation useful
Was sent to cardiology to clarify whether I was fit for surgery as an anaesthetist had told me I was suffering from heart failure. Dr Felekos checked all of my recent cardiology reports, blood results etc and was very thorough in his questioning of my symptoms.. He was very reassuring and explained his findings in a way that i easily understood. I also had an opportunity to raise any questions or concerns that I might have. Dr Felekos was very welcoming and friendly and managed to provide a relaxed atmosphere during a consultation that I’d been extremely anxious about.

Happy to help
Meeting Dr. Felekos was easily a 10/10 experience. I was able to communicate my concerns in detail and was never rushed or interrupted. The consultation was clear, thorough, and delivered with genuine care. Dr. Felekos made sure to check multiple times that all of my questions had been answered. I’m very pleased with the experience and the professionalism shown throughout.

thank you for your review
Following a failure of one of my heart bypasses Sept '25, subsequent heart attack Dec '25 and months of anxiety and uncertainty, finally I have hope of a satisfactory outcome Following the meeting with Dr Felekos who is reviewing my imaging results and has promised a follow up in 2-3 weeks.

Happy to help - I will be following up very soon with a final treatment plan
Dr Felekos is a brilliant colleague.Highly recommended
