If you have to have periodontal surgery, this is the place to get it. They use "conscious sedation," but , believe me, you have no idea what's going on. Pain is moderate afterward, but prescription drugs are VERY helpful. Follow-up is EXCELLENT. Great staff of hygienists and assistants. This was more expensive than other periodontists I checked with, but well worth it. ( Dr. Johnson was referred to me by another patient who already had the perio surgery. In my opinion, that's who you want to follow, as opposed to another dentist.)
