I've been going to Dr. Gaudio for most of my life. I have always trusted and believed in his excellent work, and his wonderful staff. I've lived in different parts of the country and have gone to different dentists, but I have always came back to Dr. Gaudio for his work. And even though today I live in Utah, I still return to Texas when I need any dental work.
