I am devastated to hear the news of Dr. Frank Ryan’s death. He was the most amazing person I have ever known. He was an angel and changed my life and the lives of everyone he met. He was the most brilliant talented surgeon who will ever exist. Dr. Frank Ryan changed the world. My thoughts and prayers go out to his mother, family, friends, and anyone who was ever blessed enough to meet him. He is in a better place. FYI Dr. Ryan never drank, never smoked, he’s never done drugs this was something everyone knows about him. He was always on call 24/7.
