Dr. Sullivan’s office is actually located in Brentwood in 37027 zip code… …But, anyhow, I have been an on again and off again(left town for school, and then again for work, etc…) patient of Dr. Sullivan since I was but a wee lad — no, literally since I first had teeth. While over the last 29 years I have gone from hygienist to hygienist, Dr. Sullivan has been the constant. Sure, he’s got older but he continues to stay on top of the latest trends(from what I can tell) and the latest techniques(again, I’m not a dentist but it’s my best guess). The office staff at the front seems nice enough and the waiting area has the pre-requisite fish and magazines for while you wait. They run fairly close to on time, every time, and I don’t have any complaints. I know some people prefer a dentist that will give them laughing gas just for a teeth cleaning because they have a fear of the dentist. I am not one of those people, so I don’t know if he offers laughing gas to those with a fear of dentistry just for a regular cleaning. All and all, I’d recommend to others.
