“My recipe for excellence in cardiology is simple: Combine extensive expertise with simple and effective communication, putting the patient at the centre of all discussions. The focus of all my consultations is not only to offer Mayo Clinic Healthcare's state-of-the-art cardiac diagnosis and treatment options but also to provide clear explanations throughout the whole patient's journey.”
