Dr. Persson is great. He walks you through every step as he treats you. There is no digging and scraping with the pick and axe during cleanings like you get at most dentists.
I have always had a tremendous fear of dentists based on experiences from my childhood. Dr. Persson has done quite a few procedures on my teeth (cleaning, filling, crowns) and I NEVER go in there nervous or anxious. He's very calming and has never caused me any pain regardless of the procedure. To top it off, he's just a really great guy.
I highly recommend Dr. Persson.
