Long time patient here, I've been a fan since 2000.
The office staff is fantastic. You will be received like they LIKE you. They're true professionals and have regular training to keep their skills at their best. True professionals, they're why I travel from Avondale to Gilbert.
Dr. Sullivan is an excellent and well-skilled cosmetic dentist. He's also reasonably conservative and a good read of his patients' concerns. He suggests treatments to keep your smile looking great, though he's also done a good job of avoiding anything over the top that would make me uncomfortable.
He's good at pain management, a huge plus.
They appreciate and respect your time. The office has - don't know what it's called - the machine that makes crowns. If you have to have one, there are not 3 appointments. 20 minutes later, it's done.
Best: if you're in pain, you can get hold of the doctor. True patient care all the way round.
