  • 5 star review  My 5 year old went from disliking her old dentist to loving her new one. I can't say enough good things about the cleanliness and professionalism of this place. They manage everything well from top to bottom and truly CARE about making your experience a good one!

    thumb Mark Chyz
  • 5 star review  One of the best experiences I've had at a dentist. Don't let the building exterior fool you, once you step inside the clinic you'll feel like you are in a high end, professional office. Very sophisticated set up, elegant waiting area, the actual dentist working area in the back is much larger than you'd expect. The team is very knowledgeable and professional, Marissa did an exceptional job doing my cleaning and examination. Would highly recommend them.

    thumb Shannon Burns
  • 5 star review  I love coming to see Dr. Bis and her staff for all my dental work. She really takes the time to go over your treatment in detail. She even uses photos to show you what’s going on in your mouth! I have always had a positive experience and everyone is very knowledgeable and experienced. I don’t know why anyone would rate this office a 1 star. This is the best dental office I have ever been to!

Why Remove Mercury Fillings

Dentistry used mercury fillings, also known as dental amalgam fillings before we identified its harmful effects. Now that we see the danger that mercury fillings pose to overall health, we know not to use them.

If you have mercury fillings, there is plenty of research available to support the decision to have them safely removed.

We are committed to providing patients with the resources and education about mercury fillings so that you can make the right decision for you.
