Dr. Carlson is a superior Periodonist. He is the best! He is very kind and extremely friendly. No pain at all. He explained everything in great detail. His staff is equally good. My general dentist Dr. Larry Allen recommended him highly. Now, I know why. We even saw Dr. Carlson at Costco. He was as pleasant as can be. This is the way it should be. I am very grateful to Dr. Carlson.
