Dr. O'Reilly is a wonderful doctor. I've been to him before. I've never had a problem. He's very understanding, very informative, and he'll actually talk and listen to you. And that's a rare commodity with most doctors. His staff is superb. They're caring, they're efficient, and they'll answer any of your questions that you have. I think he's wonderful. Please don't let him retire until I'm dead. I love Dr. O'Reilly and his staff. It's why I drive him from North Carolina to Georgia, because he's wonderful. Thank you.
