If you want the top periodontist in LA, visit Dr Handelsman. He is the kindest, calmest, and most skilled doctor I have kown. I had an implant by another periodontist which resulted in much pain and inflammation under the gum afterwards. Dr Handelsman explained the options and exactly what he was going to do to tackle the chronic issue (it had been going on for months and the other doctor kept saying it will go away on its own!). The very first treatment by Dr Handelsman (completely painless) was successful, and my problem went away within days. My only wish was that he practiced general dentistry as well...I wish I could clone him! I still drive to Santa Monica for my appointments from Valencia. Dr Handelsman is the best!
