Dr. Killian is a great doctor. We came to him for a second opinion when another doctor told us something that didn’t seem right. Fortunately, Dr. Killian disagreed with the other doctor and saved us quite a bit of trouble. In the long run, our old doctor was wrong and Dr. Killian was proven right. We switched to Dr. Killian’s practice immediately. Our sons both really like him, which isn’t something we can say about most people. I wish I could give him 6 stars.
