Dr. Terry (I have never used Dr. Carl, but I'm sure he's good, too) is a world class dentist. He did crown work in my mouth many years ago. I moved away and my new dentist (whom I consider to be equally as talented) always commented on what a nice job Dr. Terry had done. He takes great care in his work. He is a super nice guy, too. The hygienist are very good, too. The rooms face huge floor to ceiling windows that over look a beautiful yard and bird feeders.
