Yeah, Dr. Riley makes you feel comfortable and he's knowledgeable and he's just a real nice guy. Talk about tennis and fishing, makes you feel relaxed. He's a good human being and he knows what he's doing. I recommend him highly. I was going to do the surgery five years ago, it was COVID. So I actually came back home.
