I saw Dr Rosser as I was concerned about a heart murmur he explained things well and reassured me
The quality of care I received from Dr Rosser is something I feel compelled to share. As a cardiologist, he possesses a remarkable ability to make patients feel truly heard and respected. He has a very calm demeanour and took the time to explain everything clearly, which made a stressful situation significantly easier to navigate. It is rare to find a specialist who combine such a high level of skill with genuine compassionate care. Dr Rosser is a great asset to circle health group and medical association . I feel fortunate to have been under his care, and I would not hesitate to recommend him to others seeking a cardiologist.
My experience with Gareth Rosser has been first class. Kind, thoughtful and extremely knowledgeable which is exactly what you need when you are experiencing heart related issues. His responsiveness after my procedure is also superb and I would highly recommend him
Dr Gareth Rosser was caring, attentive and reassuring at a time of considerable concern. His expertise and clear assessment of the situation led to a swift and thorough diagnosis, resulting in a successful, life-preserving outcome. My family and I are deeply grateful for everything he did at the time and for the continued care and reassurance he provides through my annual reviews.
Dr Rosser was my cardiologist consultant from 2022 and under his care and guidance I ended up having a quadruple heart bypass not long afterwards. His expertise and treatment was outstanding, empathetic and supportive. I have no hesitation in recommending him to others
From my introduction to Dr Rosser through to my discharge and return to full health, I have had only the very best care and treatment. My coronary artery desease was diagnosed in 2019 and we attempted an urgent angiplasty to stent the arteries. It was not a success so bypass surgery was undertaken in January 2020. After 12 months I had some failure in the minor grafts, for which Dr Rosser rassured me we would fix by stents. In September 2021 I underwent a very successful angioplasty with 3 stents inserted and full blood flow returned. Since then my health has returned to full strength, with hiking and cycling forming a huge part of my life. In 2025 I trekked to Everest Base Camp at 5640meters, with Dr Rosser's encouragement. He encourages all patients to live full lives. Dr Rosser, didn't just safe my life, he restored it! He is the best!
I have just had my first year check up after my surgery with Dr Rosser and as always he was great with everything including his reassuring manner and his professional approach.
Dr Rosser was professional and friendly, providing clear information and the opportunity to ask questions.
Excellent Cardiologist with a very friendly nature in addition
