Dr. Mignone was kind enough to visit with me within a week of my first call to his office. He was well versed in my case and had reviewed my medical records prior to our visit. His advice and counsel, as well as outline of my options helped me to make a decision on major heart surgery at the University of Washington.

Dr Mignone talked to me like I was a person rather than a chronological number which Is the usual way doctors focus on my liabilities rather than my abilities. Despite my age I can still do many things and I think he took that Into account. He Is an excellent teacher who seems to love his profession and working with people. He took time to fully explain my condition
