I couldn't have asked for better treatment and thorough investigation.. He explained everything to me and put my mind at ease Absolutely brilliant doctor .
I was very happy with my appointment which was on time. Dr Behar explained every thing in great detail and set out the way forward.
I enjoy the visits because time is taken to explain what is happening and genuinely feel notice is being taken
Pleasant experience, straight talking and recommended some diagnostic tests. Will see doctor again to discuss results.
I switched consultants to Dr Behar and it proved to be a great decision. He gave great care and attention to my case and left no stone unturned. Sometimes consultants can be too rigid in their approach however Dr Behar struck the perfect balance and listening to why I think is right alongside his professional opinion. Would highly recommend.
First rate medical experience. Booking and organisation could use some improvements. Patient having to deal with doctor and venue somewhat separately is a bit odd, e.g. provide BUPA details to Dr, then have to give them over again to clinic. You get 2, sometimes 3 confirmations of an appointment. After a scan the clinic usually says the results will be through in a couple of days. Then usually nothing happens for 1-2 weeks. Then Sarah asks if i'd like a follow up appointment. As the patient i've no idea if I need a follow up - only you know that! I would sharpen up the organisation to match the clinical experience.
Dr Behar was friendly and straightaway made me feel relaxed and comfortable. He was very thorough with his questions and most helpful in trying to get two scans done before my pre-op assessment. I would happily recommend him to friends/family who need cardiac appointments.
Jonathan is knowledgeable, experienced, and professional, and he cares for his patients. I surely recommend him to anyone with cardiac issues.
It was fruitful. Explanations were given and I was assured appropriate tests needed to be carried out before deciding on procedure. I felt comfortable and listened to. There was no delay in informing thr next steps and ensuring they were carried out
