My name is Juan Carlos Leoni, I'm a transplant cardiologist at Mayo Clinic, Florida. I've been at the institution since 2011. I'm very passionate about what I do. I've been doing this for quite some time and I think it's a fantastic area within cardiology. I work with an excellent group of physicians and nurses and extenders who provide the best care to our patients. I've been always been very passionate about medicine since I was a kid. I used to read the, when we had the encyclopedias, I used to kind of read them from cover to cover. And I was always also excited and passionate about science and art, I think medicine really encompasses all of these areas, so be able to provide hope, be able to provide care for our patients and change their life and change ours.
