We've been to Dr Zee's office twice and both my 5-yr old and I had great experience there.
Office environment - The office is very clean and very well decorated for kids. A movie from the flat screen TV mounted in the ceiling of examination room can come in handy when your kid is being examined. Kids are also promised to get a special coin if they do a good job during the visit and they can use that special coin to get a small prize at "lottery" prize machine at the exit. If your kids love dogs, they also have a black lab there to make kids/parents who may be nervous about the dental treatment feel more comfortable.
Staff - Staff are very friendly and patient with kids. They know how to talk to kids and make them feel comfortable during the visit.
Dr Zee - She's the most energetic Dr that I've ever met. I can tell she's very passionate about what she does and she's proud of her practice.
