Welcome To Our Practice

From the moment you walk through our doors, you'll notice that we’re different from most dental offices.

For one thing, instead of asking you to take a seat in our waiting room, we invite you to relax in our living room.

Every aspect of your visit is carefully designed to provide comfort and confidence whether you’re here for a regular check-up or asleep for more complex treatment.

We specialize in family dentistry, intravenous sedation, helping people overcome their dental fears and orthodontics.
