Dr. Johnson is excellent. I used another endodonist for a proceedure previous to my last and it two are redo. The other dentist had a fancy office with flat pannel TV and when I left after 2 hours during which the other dentist saw 4 patients my bill was 900 and that was for 40% of the bill. With Dr. Johnson the experience is totally different. He is extremely patient and explains everything in detail.
Most importantly his prices are not excessive and within insurance guidelines. He is excellent.
