Dr. Zola's office is by far the friendliest dentist office I've ever been. If it wasn't for the difficulty of finding parking in Westwood Village, I'd give his office 5 stars. Sometimes, my insurance bill does not get filed the first time, but eventually it does. And I have had a pain in my molar that never seems to get addressed even though I bring it up at all my routine cleaning appointments. Got a prescription bleaching a few years back and it was very effective, although a bit expensive, as was my night guard. Overall, it's never a chore to go to the dentist, just wish it was more accessible.
