Jon Byrne listened, discussed everything thoroughly and was very kind. I don't think he can do anything to improve his manner or treatment technique.

Dr Byrne has been my guide through diagnosing, treating and after care during the last seven years or so for my mitral valve repair. Thanks to him I am in as good health as I ever could have expected at my age.
